Can you attach the last 50 lines of an strace of the commands
that cause the hangup? Just do something like:
strace vadddomain abc.com abcThanks,Michael.<snip>
This hangup doesnt happen with the latest version anymore:
Breached# cd /usr/local/vpopmail/bin
Breached# ./vadddomain test.domain.com test
It would seem he is still using vpopmail 5.3.29 as that is the only version where that "hangup" message gets produced.
