ISPConfig 3 & Ubuntu 8.04 - pop connection error

[Mali]

Hi Till, Falko !

i'v a small problem, i can't connect to pop3
i try with Thunderbird, Evolution and i'v install roundcube (same problem)

for sure, iv' create a mailbox olivier@domain.tld with a simple password ...
The domain.tld work for website, ftp, mail
i see some mail enter in mailbox and i can send mail with the shell.

sry for my bad english :/

[Mali]

all right !

sry i miss the package courier-authlib-mysql

[astewart]

Alright, I'm going to keep this topic going here.

Setup:
ISPCONFIG 3 Setup (Latest SVN) on Ubuntu 8.04
I have not been able to successfully telnet into my MailServer from outside my network.

I have all the proper ports forwarded in my router (IMAP 143, 993, POP 110, 995) which are pointing to my Servers Internal IP.

I am not using IPTABLES but I executed this anyways just to be sure:
iptables -I INPUT -p tcp --dport 110 -j ACCEPT
iptables -I INPUT -p tcp --dport 143 -j ACCEPT

I have no problems accessing Squirrelmail and logging in with the user accounts. I just can't setup the accounts in any Mail Client or get them working. (Or telnet)

I have no problems telnetting into POP3 and IMAP from within my Network.
When I do telnet from an external source it doesn't even get logged in the mail.log or the sys.log. I figured that there would be some sort of indication why I can't login but there is nothing in any log.

[Mali]

try to open port 25 no ?...

[astewart]

Sorry, Port 25 is also open on the router. I didn't mention it seeing that I have no problems sending E-mails via Squirrelmail.

Also no problems telnetting into port 25 internally:
user@server:~# telnet 192.168.2.60 25
Trying 192.168.2.60...
Connected to 192.168.2.60.
Escape character is '^]'.
220 domain.tld ESMTP Postfix (Ubuntu)

I'm all out of options guys :(
Any other ideas?

[till]

If you can send emails with squirrelmail, and local telnetting works, then its a problem on your router or your internet service provider blocks port 25.

[astewart]

I basically ruled out that its my ISP blocking ports because I have a VM image running Ubuntu 6.10 and ISPCONFIG 2.2.29 (Used Perfect Setup) and I have no problems telnetting in externally when I have it up and running.

I can't seem to figure it out though... :(

[falko]

And is your router forwarding port 25 still to that Ubuntu 6.10 vm, or to the Ubuntu 8.04 server?

[astewart]

Nope, I have all the necessary ports forwarded to the my current 8.04 Ubuntu Server. I've tested this a few times trying to figure out what is different between the two but no luck. I recently switched back to 6.10 vm for testing purposes and I have no problems.

This is crazy, its driving me nuts, lol

[till]

As you posted above that your ISP blocks port 25, in this case you can not run a mail server on this connection.

[astewart]

I never actually mentioned in any posts that 'My ISP Blocks port 25'.

This wouldn't be the case anyways seeing that my 6.10 Ubuntu Server has no problems at all when telnetting in via the mail server.
