I'm not positive that this is a vpopmail issue, but am leaning more
towards vpopmail than qmail. Perhaps it is a known issue, but I haven't
been able to get any decent search results for it.
When the .qmail-default file is set to bounce, mail for accounts with or
without a .qmail-user file works fine.
But when I set a catchall account in the .qmail-default file, if an
account doesn't have a .qmail-user file, messages destined for that
account are sent to the catchall account.
And when I delete the .qmail-default file outright, accounts that don't
have a .qmail file bounce mail destined for them, and work if the
.qmail- file routes mail to their Maildir/
So overall, if the .qmail-defaul file is set to anything other than
bounce or delete, accounts need a .qmail-user file to be able to receive
mail.
I upgraded to the latest 5.4.13 version and observed the same behavior.
Has anyone seen this before?
