The setup has been running well with vpopmail 5.4.9 for past few years.
Due to very heavy load on qmail-scanner we decided to implement John
Simpson's validrcptto.cdb to filter out invalid recipients before
messages hit qmail-scanner. As part of this we upgraded vpopmail to
5.4.27 in order to get the onchange functionality. The validrcptto
mechanism now works perfectly.
After re-reading this, it may not be vpopmail's vdelivermail process
rejecting the message. It may be a qmail process. Just something
to think about.
No, because just reverting back to vpopmail 5.4.9 solves the issue without touching qmail in any
way. Its the combination of maildirsmtp and vpopmail 5.4.27 thats causing the trouble. Everything
else is working fine.
