postfix doesn't work correctly

[LeoLinux]

Hi there,

My email workst just the half way as it should ;-) I didi anything wrong or forget something but I couldn't find it by myself.
I can connect to the mailserver with outlook and thunderbird etc.. even the webinterface (roudcube and squirrelMail works fine. recieving mails works correctly, but sending mails doesen't work.... in outlook express it says ... mail server not found ... in thunderbird the same .. that sounds as if I forgot something .... ;-/ but what ?


here my postfix main.cf:

# See /usr/share/postfix/main.cf.dist for a commented, more complete version

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

myhostname = server1.pc1service.gotdns.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
#mydestination = server1.pc1service.gotdns.com, localhost.pc1service.gotdns.com, localhost
relayhost =
mynetworks = 127.0.0.0/8
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all

smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom
home_mailbox = Maildir/

virtual_maps = hash:/etc/postfix/virtusertable

mydestination = /etc/postfix/local-host-names


I'm using POP...


thanks for helping ;-)

best regards Leander

Do you use an FQDN or an IP address in your email client as SMTP/POP server? If you use an FQDN, I guess it's a DNS problem.
What's the output of netstat -tap and iptables -L?

[falko]

I'm having two problems with postfix:
- can't login or send using Apple Mail with either POP or IMAP, server responds but then rejects my password
- Roundcube won't work, can't log in
- when I send mail via ISPConfig webmail, gmail thinks it's spam and hotmail doesn't deliver it (presumably for the same reason)!
- I've created one main domain with several Co-Domains in ISP Config, will I be able to create e-mail addresses info@domain1.com info@domain2.com with separate mailboxes for each one?

I'd like to be able to log into my mail accounts with IMAP and POP, as well as use Roundcube for webmail.

I have a dynamic IP - so I use DynDNS...what do I have to change?

Thanks!

This looks fine so far. Is your workstation inside your private network? What did you use as SMTP server in outlook? Your dyndns domain or your internal IP address?

[LeoLinux]

The Server is inside a Privat Network (192.168.1.101) The Ports are successfully forwarded.


WAN TCP 25 (SMTP) 192.168.1.101 25 (SMTP) SMTP-Server1
WAN TCP 110 (POP3) 192.168.1.101 110 (POP3) POP3-Server1
WAN TCP 143 (IMAP) 192.168.1.101 143 (IMAP) IMAP-Server1
WAN TCP 993 192.168.1.101 993 IMAPs-Server1
WAN TCP 995 192.168.1.101 995 POP3s-Server1



my Outlook entries:

POP-Server: pc1service.gotdns.com and as SMTP-Server the same. POP works, SMTP not ;-/

for what is the optipn Backup MX in DynDNS.org? Is it necessarry to tick this option?

Your modifications have been completed. Details of the new settings are below.
Hostname: pc1service.gotdns.com
IP Address: 84.164.159.69
Wildcard: Y
Mail Exchanger: none
Backup MX: N


root@server1:~# hostname
server1.pc1service.gotdns.com
root@server1:~# hostname -f
server1.pc1service.gotdns.com

[falko]

You don't need the Backup MX.

Is your client PC in the same network than your mail server? If so, please try your mail server's internal IP address in your email client.

I guess your ISP is blocking port 25. I'd contact them and ask.

Hi Till,

you guessed right ;-) - now it's able to communicate with the server. But if I try to send an email it says that the mail is to big to send but there is only the word test in it no attachments and stuff like that. The mailbox should be big enough - so what's the matter?
and how to fix that the server is able to communticate without beeing in the localnetwork?

Thank you and Falko very much ;-)

[edit]
SquirrelMail suddenly shows me this error when I'm trying to send an email via the webinterface .. ?!

Requested action not taken: insufficient system storage
Server replied: 452 Insufficient system storage

^^ I think my harddrive is full - only 13MB left ... have to check (& renew) this out first ...

You can try to remove some of the old logfiles in /var/log

[LeoLinux]

Ok I did. So now it's working if I enter the IP adress instead of the domain. but only in the local network ant not from outside ;-)

any idea? ports in the router are forwarded and tested with nmap ... :-?


thx! Leander

[till]

Does it work when you use your external IP?

[LeoLinux]

I don't really know what I did wrong - but I reinstalled _everything_ the OS and ISP and now it seems to work except .....
