vpopmail does not affect outgoing mail.  It controls whether or not certain
IP's are allowed to relay mail when connecting to qmail-smtpd.

tcp.smtp (compiled into tcp.smtpd.cdb) controls which IP's are allowed to
connect to tcpserver.  It defaults to allow (which would be a single
":allow" line).  Setting RELAYCLIENT for an IP tells qmail-smtpd to allow it
to relay mail.

Normally, this file contains all IP's on your network, assuming you want
them to relay through qmail.  The following is an example.  RBLSMTPD is only
needed if you are using rblsmtpd.  Leaving it blank tells rblsmtpd to not
perform lookups against that address (you don't want it looking up your own

If your domains directory is on /var, then make sure you have enough space
for all the mail.

As a tip, you can get rid of QMAILDUID and NOFILESGID by adding -U to the
tcpserver command line and using "envuidgid qmaild" as the first thing after

Does your tcp.smtp file set RELAYCLIENT for the IP that you are sending

vpopmail will create vpopmail/etc/open-smtp that it merges with tcp.smtp
when building tcp.smtp.cdb.  It does this automatically for any IP that
successfully authenticates via POP3 (or anything using vchkpw, such as
Courier IMAP).  tcp.smtp.cdb is automatically rebuilt when this happens.

You need to make sure vpopmail/bin/clearopensmtp is being run from cron
every 30-60 minutes, otherwise these IP's will never expire.
