Have recently re-installed the Qmailadmin program, and now users added to a domain through either vpopmail or qmailadmin show up in the qmail-send logs as no_mailbox_by_that_name. Telnet to port 110 with the username and password works, but email to those users bounces. Anyone have any ideas? This could also be a Qmail configuration issue, but I don't know enough about vpopmail to troubleshoot this.
Thanks in advance for any help. Dave
