I'm having trouble sending email to a specific domain (@gic.com.sg).  We are receiving emails from them, but if we try to reply or send a new message it is first delayed and then it fails.

I tried to telnet from the server and I got the following error "could not open connection to the host on port 25: connect failed"

All other email seems to be working fine.

Please check your server configuration, reverse DNS record and IP address on Blacklist sites.  The details of which and how to make sure you ar RFC compliant can be found in my article:

duh.  I don't know why it didn't occur to me to check if WE are on a blacklist.  Ug.  Thanks a ton.  It's always the simplest solutions that seem to go right over my head.

Sometimes it's the simple stuff that can be overlooked.

Glad you are sorted - now you just have to work our why you are blacklisted.

Thanks for the points.
