Default mail stopped working

Hi,

I've a Squeeze Perfect Server installation with Bind Dovecot and Apache2.
After the above installation I installed Roundcube and everything was working fine.

I installed a secure certificate recently with StartSSL using that how-to.

It seems my own mail is no longer working, nor is anyone elses.

I've noticed that under Monitor I do have several requests in the mail queue for the last several days only.

There is nothing in mail.err log.

Every hour root gets mail from cron saying ispconfig/server/server.sh with a warning: "There is no public key available for the following key id: xxxxx"

I actual have a directory that's gone missing, where I keep my individual daily database backups. Not sure how that happened. I'm the only one with root password, but I haven't changed the password for a while.

I would like to get mail working again but not sure where to look.

Any help would be greatly appreciated.

Thank you.

Please take a look into the mail.log file in /var/log/ folder and post the errors that you get there. Most likely a wrong or no key file is installed for the ssl cert in postfix and /or dovecot.

Default mail.log errors

Till, thank you for your help.

I created a mail account for a site that had none. Then sent from my Outlook account an email to it. Also I signed into the new account in Roundcube an saw my welcome message. I sent an email to my outlook account from Roundcube. That was at 10:55 and 10:56 respectively.

Since then the mail.log has been ablaze with activity about my email attempts.
So far the mail has not been delivered in either direction.

Also under /var/mail/ the expected new user record was not created, webnn.

Also I did a netstat -tapn and dovecot is listed but not postfix.

Here is the output from mail.log, but I don't see "errors".

The welcome message indicates that the local mailsystem is working correctly. To test if its a local issue or a remote issue, please login to roundcube, then send a email to the same address that you used for the roundcube login. It should be visible in the inbox within 1-2 minutes.

Till, thank you again for your response and help.

Yes, you are right the mail was delivered to the same account that sent it in less than 1 minute.

I'm quite sure that my system has been hacked and I'm wondering if fail2ban is working properly. I remember, it may have been when I was running Fedora not sure, but I used to get messages to root mail all day long about IP addresses being banned. I don't get them anymore. I'm wondering if fail2ban is working properly? I've copied the log from Monitor and pasted it below.

Ok, thats good.

So the eror might be one of the following problems:

- Your server blocks external mail connections:

Please post the output of:

iptables -L

and

netstat -tap

- Your internet access provider which provides the internet connection to yourserver blocks port 25 or there is a router between the server and the internet whcih blocks port 25.
- There is a dns problem, e.g. the MX record does not point to the server. Test the dns record(s) of the domain with e.g. intodns:

http://www.intodns.com/

The Ban / Unban messages indicate that fail2ban is working correctly, at least for SSH.

If you wnat to test it for other services you will have to use e.g. a mail client (not webmail) or a external FTP client and enter a wrong password more then 5 times.

If you think that the system has been hacked, then you should check it with rkhunter:

rkhunter --update

and then

rkhunter -c

The most important part is if there are any rootkits found. In the first part which checks the binaries you will most likely see some false positives.

Code:
Category 	Status 	Test name 	Information send feedback
Parent 	Info 	Domain NS records 	Nameserver records returned by the parent servers are:

ns01.delcowebhosting.com.   ['71.225.4.213']   [TTL=172800]
ns02.delcowebhosting.com.   ['71.225.4.213']   [TTL=172800]

g.gtld-servers.net was kind enough to give us that information.
Pass 	TLD Parent Check 	Good. g.gtld-servers.net, the parent server I interrogated, has information for your TLD. This is a good thing as there are some other domain extensions like "co.us" for example that are missing a direct check.
Pass 	Your nameservers are listed 	Good. The parent server g.gtld-servers.net has your nameservers listed. This is a must if you want to be found as anyone that does not know your DNS servers will first ask the parent nameservers.
Pass 	DNS Parent sent Glue 	Good. The parent nameserver sent GLUE, meaning he sent your nameservers as well as the IPs of your nameservers. Glue records are A records that are associated with NS records to provide "bootstrapping" information to the nameserver.(see RFC 1912 section 2.3)
Pass 	Nameservers A records 	Good. Every nameserver listed has A records. This is a must if you want to be found.
NS 	Info 	NS records from your nameservers	NS records got from your nameservers listed at the parent NS are:

ns02.delcowebhosting.com  ['71.225.4.213']   [TTL=86400]
ns01.delcowebhosting.com  ['71.225.4.213']   [TTL=86400]

Pass 	Recursive Queries 	Good. Your nameservers (the ones reported by the parent server) do not report that they allow recursive queries for anyone.
Pass 	Same Glue 	The A records (the GLUE) got from the parent zone check are the same as the ones got from your nameservers. You have to make sure your parent server has the same NS records for your zone as you do according to the RFC. This tests only nameservers that are common at the parent and at your nameservers. If there are any missing or stealth nameservers you should see them below!
Pass 	Glue for NS records 	OK. When I asked your nameservers for your NS records they also returned the A records for the NS records. This is a good thing as it will spare an extra A lookup needed to find those A records.
Pass 	Mismatched NS records 	OK. The NS records at all your nameservers are identical.
Pass 	DNS servers responded 	Good. All nameservers listed at the parent server responded.
Pass 	Name of nameservers are valid 	OK. All of the NS records that your nameservers report seem valid.
Pass 	Multiple Nameservers 	Good. You have multiple nameservers. According to RFC2182 section 5 you must have at least 3 nameservers, and no more than 7. Having 2 nameservers is also ok by me.
Pass 	Nameservers are lame 	OK. All the nameservers listed at the parent servers answer authoritatively for your domain.
Pass 	Missing nameservers reported by parent 	OK. All NS records are the same at the parent and at your nameservers.
Pass 	Missing nameservers reported by your nameservers 	OK. All nameservers returned by the parent server g.gtld-servers.net are the same as the ones reported by your nameservers.
Pass 	Domain CNAMEs 	OK. RFC1912 2.4 and RFC2181 10.3 state that there should be no CNAMEs if an NS (or any other) record is present.
Pass 	NSs CNAME check 	OK. RFC1912 2.4 and RFC2181 10.3 state that there should be no CNAMEs if an NS (or any other) record is present.
Warn 	Different subnets 	WARNING: Not all of your nameservers are in different subnets
Pass 	IPs of nameservers are public 	Ok. Looks like the IP addresses of your nameservers are public. This is a good thing because it will prevent DNS delays and other problems like
Pass 	DNS servers allow TCP connection 	OK. Seems all your DNS servers allow TCP connections. This is a good thing and useful even if UDP connections are used by default.
Warn 	Different autonomous systems 	WARNING: Single point of failure
Pass 	Stealth NS records sent 	Ok. No stealth ns records are sent
SOA 	Info 	SOA record	The SOA record is:
Primary nameserver: ns01.delcowebhosting.com
Hostmaster E-mail address: webmaster.delcowebhosting.com
Serial #: 2013021901
Refresh: 28800
Retry: 7200
Expire: 604800   1 weeks
Default TTL: 86400
Pass 	NSs have same SOA serial 	OK. All your nameservers agree that your SOA serial number is 2013021901.
Pass 	SOA MNAME entry 	OK. ns01.delcowebhosting.com That server is listed at the parent servers.
Pass 	SOA Serial 	Your SOA serial number is: 2013021901. This appears to be in the recommended format of YYYYMMDDnn.
Pass 	SOA REFRESH 	OK. Your SOA REFRESH interval is: 28800. That is OK
Pass 	SOA RETRY 	Your SOA RETRY value is: 7200. Looks ok
Pass 	SOA EXPIRE 	Your SOA EXPIRE number is: 604800.Looks ok
Pass 	SOA MINIMUM TTL 	Your SOA MINIMUM TTL is: 86400. This value was used to serve as a default TTL for records without a given TTL value and now is used for negative caching (indicates how long a resolver may cache the negative answer). RFC2308 recommends a value of 1-3 hours. Your value of 86400 is OK.
MX 	Info 	MX Records	Your MX records that were reported by your nameservers are:

10   mail.lightningflatscreenmounting.com   71.225.4.213

[These are all the MX records that I found. If there are some non common MX records at your nameservers you should see them below. ]
Pass 	Different MX records at nameservers 	Good. Looks like all your nameservers have the same set of MX records. This tests to see if there are any MX records not reported by all your nameservers and also MX records that have the same hostname but different IPs
Pass 	MX name validity 	Good. I did not detect any invalid hostnames for your MX records.
Pass 	MX IPs are public 	OK. All of your MX records appear to use public IPs.
Pass 	MX CNAME Check 	OK. No problems here.
Pass 	MX A request returns CNAME 	OK. No CNAMEs returned for A records lookups.
Pass 	MX is not IP 	OK. All of your MX records are host names.
Info 	Number of MX records 	OK. Looks like you only have one MX record at your nameservers. You should be careful about what you are doing since you have a single point of failure that can lead to mail being lost if the server is down for a long time.
Pass 	Mismatched MX A 	OK. I did not detect differing IPs for your MX records.
Pass 	Duplicate MX A records 	OK. I have not found duplicate IP(s) for your MX records. This is a good thing.
Pass 	Reverse MX A records (PTR) 	Your reverse (PTR) record:
213.4.225.71.in-addr.arpa ->  c-71-225-4-213.hsd1.nj.comcast.net
You have reverse (PTR) records for all your IPs, that is a good thing.
WWW 	Info 	WWW A Record 	Your www.lightningflatscreenmounting.com A record is:
www.lightningflatscreenmounting.com  [71.225.4.213] 
Pass 	IPs are public 	OK. All of your WWW IPs appear to be public IPs.
Pass 	WWW CNAME 	OK. No CNAME

Default router

Linksys wireless router:

Block Anonymous Internet Requests: ON
Filter Multicast: ON
Filter IDENT(Port 113): ON

Access Restrictions:
No blocked services
No website blocking

Applications:
Along with everything Apache and DNS, SMTP, and POP3 all are sent to the local address of my server.

Default

iptables and netstat output are fine, postfix is listening on all network interfaces on port 25 and 587 and it is not blocked by a local firewall.

The dns record seems to be fine as well.

I then tested if I'am able to connect to your server on port 25 or 587 from outside but that not possible. I then tested the same for port 80 (apache) and this works.

So it seems that somehow the email ports are blocked between the internet and the server.

As you mentioned that this setup worked before, do you remember anything that happened right before the problems started that might be realted to the issue, e.g. did you configure something in the router or did youraccess provider announced any changes in ther service?

Till, thanks again for your response and help.
Two months ago, I installed a StartSSL class2 certificate. Following that I set up 2 sites in Joomla. Before that I know mail was working because I did a site for a guy and tested that his mail was working.

When I got a complaint about mail not working, first I checked root mail, which I should check more frequently. That's when I noticed that my daily MySQL backups had stopped working. Reason: the backup directory was missing. That's why I thought I was hacked.

I don't remember any notice from my ISP about changes. Perhaps the next step is to contact them and ask what's going on.
