I' ve a problem on my mail server (Redhat Linux 5.2, MTA:sendmail) that
outgoing mails are not going to domains like Yahoo.com, Rediffmail.com and
Hotmail.com only. Other mail services are OK. The mail server is behind a
firewall and I checked that there is no reule governing this problem. What
could be the problem? Is there any way to check this?
One more thing, is there any way to activate the mails in the queue to send
again without shutdown the server?
Thanks in advance
