I am having problem sending an email Please see following error and advice what could be wrong with mail servers? Is there any problem with remote mail server (whopak.org) or local mail server (isb.comsats.net.pk)?

The problem is what it says. It timed out. That could be them, it could be you, or it could just be the internet in a lousy mood.

It's transient, which means it will retry.


You can do a manual telnet to port 25 on the remote system and try to see what its problem is:

$ telnet mail.somewhere.com 25
