I encountered a problem with a host provider that they were unable to fix. I'm not new to system administration, however this system was not under my control so I thought I ask if anyone had experience with this issue. However my question was put on hold and I'm not sure why: Sending email via php generates exim error after cPanel upgrade
After consulting with the cPanel group I found the solution and would normally post it as an answer but my question is on hold. Is this type of question not on topic for serverfault? Should I have asked somewhere else?
