I'm using Fedora 7,postfix,apache 2.2 for my mail server and its behind a cisco fix firewall. I'm running openwebmail and I can access it without any problem from everywhere except from one location. When somebody login to webmail from that location and try to send a mail it just hangs and httpd log gives this error..

request failed: error reading the headers, referer: http://my.domain.com/cgi-bin/openweb...se_caller=main

So I installed squirrel mail which uses php. There also same problem occures..

Hmm.. Do you have access to the pix firewall? Can you vheck the ACL-s ?

I can get access .. But what should I check as this location uses dynamic ips as my location. And also as I can access it from my place .. can it be a ACL cofig ?

nothing to do with programming. moved to Linux - Newbie.
