Trouble sending mail

I have just completed my first ISPConfig installation (after a 'perfect Debian setup'). Most things seem to work fine, except I had trouble logging into the webmail first, but after switching to Courier imap (as suggested on this forum) that worked too.

No the only issue is that I cannot seem to send mail for external delivery. If I try so send to some gmail receipient, I get logs showing:

Code:

Feb 18 12:32:15 montblanc postfix/smtp[10637]: connect to gmail.com[216.239.57.107]: Connection timed out (port 25)

Feb 18 12:32:45 montblanc postfix/smtp[10637]: connect to gmail.com[64.233.161.107]: Connection timed out (port 25)

Feb 18 12:33:15 montblanc postfix/smtp[10637]: connect to gmail.com[64.233.171.107]: Connection timed out (port 25)

I have tried some of the suggestions testing for fire wall issues, but 'telnet mx2.hotmail.com 25' fron the system gives:

Code:

Trying 65.54.244.168...

Connected to bay0-oim-f.bay0.hotmail.com.

Escape character is '^]'.

Violations will result in use of equipment located in California and other states. Sat, 18 Feb 2006 05:33:44 -0800

That seems okay to me to. Further 'netstat -tap' gives:

And that leaves me pretty much clue-less...

Any suggestions much appreciated, thanks a lot!

Is your server hosted on your DSL line? Many providers block email connections from IP addresses that are from Dialup accounts, this includes modem and dsl accounts.

Thanks for the suggestion. My server is hosted on a DSL line. Is there some way to test if this is the problem here? And if so, are there ways around this issue? Would I need to find an external smtp for outgoing mail?

Thanks again!

Can you send to other (non-hotmail) accounts?
You could contact Hotmail and ask if the block dynamic IP addresses.

You could use an SMTP server for relaying. You do it like this:

Thanks, this made me think; I do have a fixed IP. I have a router which does some NAT functions, so my server resides effecitvely on 192.168.1.X.

Further, I have not been able to send to different accounts either.
I include the bounce message which was generated on such occasion:
(replaced sender domain with XXX ande receiver with YYY)

The error message is saying that the mailbox does not exist on the receiving server.
Is e.van.der.meulen@YYY.com an email address on a remote server, or is it on the same server that you use for sending?
