[rt-users] Postfix sendmail returning status code 75

Thanks for your reply, Kevin, and here are my answers to your questions.

We are monitoring the box with Icinga. I will talk with my colleagues
to see if we can tweak the Icinga configuration so it complains
earlier when memory starts to get low. The box has 8Gb installed, but
it runs more stuff than just RT.

Well, I'm certainly not. And it didn't make the problem go away, so I
assume this is a dead end and I will remove that option.

postfix/sendmail[26576]: fatal: wwwrun(30): No recipient addresses
found in message header

My "sendmail wrapper" is now in place and I will be watching closely
tomorrow. Today from what I managed to capture it looked like nothing
(or only one byte?) was being piped from RT to "sendmailpipe". This is
consistent with what was written to the log (No recipient addresses
found).

Thanks!
