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)

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.

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!

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)

Code:

Hope this helps a little.

Thanks all!

 

The error message is saying that the mailbox does not exist on the receiving server.
Is [email protected] an email address on a remote server, or is it on the same server that you use for sending?
