I rebuilt the OS, rebuilt the kernel, rebuilt vpopmail (same version)
-- to no affect. I was able to get it working again with a relatively
minor fix. I'm documenting it here in case it helps anyone else.
In /usr/local/vpopmail/etc/ there are files: open-smtp,
open-smtp.lock, and tcp.smtp. I removed the lock file and renamed the
other two to get them out of the way:
-rw-r--r-- 1 root vchkpw 1874 Sep 17 08:11 open-smtp
-rw-r--r-- 1 root vchkpw 302746 Sep 13 10:00 open-smtp.HIDE
-rw-r--r-- 1 root vchkpw 0 Sep 17 07:55 open-smtp.lock
-rw-r--r-- 1 vpopmail vchkpw 4015 Sep 17 08:11 tcp.smtp.cdb
-rw-r--r-- 1 vpopmail vchkpw 2112 Sep 17 07:59 tcp.smtp.cdb.HIDE
I was then able to POP in sucessfully.
Is there some way I should have been able to detect this problem?
Perhaps cranking up a debug flag and examining logs?
I don't know the code enough to know which binaries use these, but it
looks like they all use open-smtp. Any clues for future similar
problems would be appreciated. If crash-related damage caused this,
is it something that's worked-around in modern versions of vpopmail?
