HELP! mail problems still!!

[Griff]

Hi,

Whenever a client tries to send an email they keep getting an auth error i have remoted there machines and set it up for authorisation but it's saying incorrect username/password i have checked through the forums but could not see a fix for this in any of the posts.

I am running Debian from Perfect Setup Guide.

they can recieve there POP emails perfectly fine and i am able to send mails using my master domain account but it's the other domains that cannot send i even setup a domain as a test to see if it was something in there config and i copied the settings from my domain to the test domain but it's still coming up with the same error.... I have tried username "web<num>_<name>@domain" and "web<num>_<name>@masterdomain" aswell as "web<num>_<name>" but to no avail.

All help greatly appreciated.

Thanks in advance.

Griff

What's the exact error message? What's in your mail log?

[Griff]

Sending of message failed:

The message could not be sent because connecting to SMTP server zcubed.co.uk failed. the server may be unavailable or refusing smtp connections. Please verify that your SMTP server setting is correct and try again, or else contact your network administrator.

which logs would you like to see? postfix or user mail logs?

Make sure your firewall doesn't block port 25. What's the output of netstat -tap?

which logs would you like to see? postfix or user mail logs?It's the same log file, usually in the /var/log directory.

lol the mail log hasn't been touched since december apparently .. above is the outcome of iptables -L

Thanks Again for all your help

[Griff]

Sorry that wasn't very helpful.

the mail.log file is totally empty the only mail.* file with anything at all in is mail.log.ispconfig ... Hope this helps to clear that up a bit.

according to the mail.log.ispconfig the last time the log was touched was december last year and then it died ... more info is on the actual log.

[falko]

Is 70.147.153.67 your public IP address?
You don't have a DNS record for server1.zcubed.co.uk...

[Griff]

Yes that's the servers ip address... i tried to remove server1.zcubed.co.uk before but FTPD kept sending server errors so i ended up putting it back... so should i create a co-domain or how will this work? sorry for this but my Tech used to do all of this but he's recently passed away so i'm having to learn V quickly.

[Griff]

sorry for late reply have been working all day and night... i'm always trying to find a way to get access to my sites but the work's server don't allow internet access just Intranet

[falko]

You can add server1.zcubed.co.uk to /etc/hosts for now. That replaces the missing DNS record.

[Griff]

That's whats in there currently? but it's still not letting me send the emails

[falko]

What's in your mail log now when you try to send an email?

[Griff]

The mail log is still empty...

that seems wrong to me... all of the other mail logs are empty even mail.err and mail.info and mail.warn.

Still the same error occuring when trying to send an email.

[till]

I guess the log is a bit old "Dec 13 01:21:45", or is the date set wrong on your server?

The ISPConfig log is always a backup copy of your mail log, if the maillog save option in ISPConfig is enabled.

[Griff]

just done a quick check in the server settings and mail logs should be saved in /var/log/mail.log and Save Log is ticked so yep it should be logged but it's not... now i'm really baffled...?

[Griff]

also just checked some of the other files Mail.warn.0 and that's also got a repeat of the mail.log.ispconfigsave in there... does that error above not mean that postfix isn't running?


Dec 13 01:21:45 localhost postfix/postfix-script: stopping the Postfix mail system
Dec 13 01:21:45 localhost postfix/master[6797]: terminating on signal 15


i've done ./etc/init.d/postfix start and got


Starting mail transport agent: Postfix.

[falko]

The restart shoud have got logged in /var/log/mail.log. Do you see it there?

[Griff]

nope still don't see anything in the mail.log it's still empty... shall i try to do the restart using ispconfig?

[falko]

nope still don't see anything in the mail.log it's still empty...
Then your system seems to be really messed up. Does Postfix log to any other file?
Maybe you have a rootkit on your server. Check it like here: http://www.howtoforge.com/faq/1_38_en.html

[Griff]

just ran CHKROOTKIT and only got the following outcome


server1:/# chkrootkit -q
eth0: PACKET SNIFFER(/sbin/dhclient[1004])
server1:/#


where possible i don't want to format and start again.

Thanks

[falko]

I suggest you redo the Postfix configuration from the appropriate "Perfect Setup" on HowtoForge.

[Griff]

ok i've re-done the postfix configuration and now i'm getting a totally different error... the error i'm getting now is


An error occured while sending mail. The mail server responded: <djgriff[NOSPAM]gmail.com: relay access denied. Please verify that your email address is correct in your Mail Preferences and try again

[falko]

Please enable "Server requires authentication." in your email client.

[Griff]

have already got that enabled but stil that error

[falko]

have already got that enabled but stil that error
Can you post a screenshot of that setting in your email client here?

[Griff]

http://www.zcubed.co.uk/mail.jpg

[falko]

You must fill in the user name under "Use name and password". Then when you send the first email Thunderbird will ask you for the password.

[Griff]

tried that am still getting a password error...
i've tried web1_NAME, name@domain, web1_name@domain
no joy :(

[falko]

web1_NAME is correct.
Does zcubed.co.uk point to the correct server? You can check with
dig zcubed.co.uk

And there's still nothing in your mail log?
Is 70.147.153.67 your public IP address? Is your server in a local network? If so, do you forward port 25 from your router to your server?

[Griff]

it's on it's own line and Port 25 has been opened unless it's the ISP that's blocking it but i don't see why they're gonna do that when it's a T3 Line, Port 25 is forwarded i've even done a portscan to check from an outside source and all signs are pointing to open. 70.147.153.67 is the Public Static IP yes.

[falko]

What's the output of iptables -L?
Please also ask your ISP to go sure they don't block port 25.

[Griff]

Rite have finally managed to get through to tech support and they've said port 25 isn't blocked as many of our clients run there own mail servers. that's that option gone..


server1:~# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination
server1:~#

[falko]

Then it could be a problem with your router not supporting loopbacks into your local network. Does email authentication work outside your network?

[Griff]

sorry i'm a n00b to this can you please explain that a little more... how would i check that? i can send emails from another server which is running from the same center but i can't send emails from this server.... we have a fixed IP dedicated to that machine... i dunno if that's what you mean.

[falko]

Well, I was thinking that your server is in a local network, behind a router. But if it has its own public IP address, then forget my previous post...

[Griff]

ok i've just found out my server IS on a router but it's got it's own static ip ... i've just changed the IP to one of the others and updated everything but it's still not working... any more ideas? i've got a suggestion but i don't know how you'd feel about it ... drop me an email to griff <NOSPAM> zcubed.co.uk and i'll email you the server details so you can login as root and have a look incase i've messed up somewhere... just an idea...

Regards

[falko]

ok i've just found out my server IS on a router but it's got it's own static ip ...
Is it a public IP address, or a local one? What's the output of ifconfig?

Yes i know that the IP has changed but i've updated it on the router we've got 20 dedicated IP's to our router and i was given 10 at purchase i tried to change incase the IP was causing a problem

I get this when I try to connect to your server:

[Griff]

one other thing that i find strange is that i can emails perfectly fine from the webmail client??? i don't know what smtp server the webmail uses or if i'm perhaps trying to use an incorrect smtp server ... the smtp i'm trying to use is zcubed.co.uk is there anyway to check the CONF for the webmail system as the preferences don't give any information what so ever... is it user error or a relay error??

Thanks

[till]

The webmail uses lawyas your local smtp server trough the "sendmail" command (which is provided by postfix and sendmail).

[falko]

[falko]

This means that the mails don't even arrive or go through your server, most likely because of wrong DNS records, a misconfigured firewall, etc.
Please check your DNS records again with dig.

And you don't see anything in your mail log when you send a mail? :confused: Then you should check the settings in your email client. What do you use as SMTP server in your email client? Did you try the IP address (70.147.153.69) to go sure it's not a DNS issue?

[Griff]

When trying with the IP i'm getting the following error message:

The message could not be sent because connecting to SMTP server 70.147.153.69 failed. The server may be unavailable or is refusing SMTP connections. Please verify that your SMTP server setting is correct and try again, or else contact your network administrator.

When trying with the IP i'm getting the following error message:

Do you have a desktop firewall? That might also be the problem. Try to switch it off for testing purposes.

I get this:

telnet 70.147.153.69 25
Trying 70.147.153.69...
Connected to 70.147.153.69.
Escape character is '^]'.and then it hangs. So Postfix is running, but I guess myhostname is wrong. What's in /etc/postfix/main.cf and in /etc/resolv.conf?

Edit: Forget the above, it just took a little bit longer (10 seconds or so) until the server responded. This is the output:

mh1:~# telnet 70.147.153.69 25

As far as I can see this is ok. Please check your desktop firewall.
