Hi, I searched around but didn't see anyone else having this problem.. I have a newly installed server running CentOS 3.3 and using the provided RPM for Squirrelmail (ver 1.4.3a-7.EL3.centos.1).. When I try to send an email I get the following error.. "The connection to www.mydomain.com:80 has terminated unexpectedly. Some data may have been transferred" I am using a Firefox browser so the error may be worded differently in IE.. Anyone have a fix for this or any idea whats causing it?
