Re: Error after restart

In this case with a stale PID-file, do as you're prompted. Stop all Zimbra services (confirm w/zmcontrol status) and see if /opt/zimbra/log/httpd.pid exists. If so cat the PID-file and see if there is a process with that number (I think there shouldn't be). Remove the file manually. Try restarting Z...

Re: Subject editing based on email headers...

Hi Jim, Thanks for sharing your thoughts on this. I wasn't clear on this statement? Given you probably digitally sign your domains, it would be harder to spoof and an additional clause could strengthen against FN/FP's? I like that there are some possibilities with Amavis/SA but was hoping (ha!) not ...

Subject editing based on email headers...

Hi All, I've got a client who is pretty interested in pre-pending "(External Sender)" to the subject of any email they receive that does not come from their own domain. I've poked around with postfix header_checks and got a POC going (on an 8.8.15 deployment) on plain old subject-editing b...
