Hi, I am running RedHat Linux 7.1 (all patches applied), and I can only send out emails, but cannot receive emails.
ps x tells me that sendmail (is) accepting connection.
I tried to restart several times, but no fix. (I am a newbie in Linux).
My connection to the Internet is T1, and my httpd and sshd and others are working just fine. If anyone could help me on this, I would be grateful!
