When I want 2 upgrade from 5.2.2, I meet this problem.
POP b4 SMTP works with 5.2.2, but fails with 5.4.X
The roaming IP is logged into MYSQL relay table,
but not logged into ~vpopmail/etc/tcp.smtp.cdb as 5.2.2.
My configure line:
./configure --enable-auth-module=mysql \
--enable-roaming-users --enable-logging=v \
--enable-tcprules-prog=/usr/local/bin/tcprules \
--enable-tcpserver-file=/home/vpopmail/etc/tcp.smtp \
--enable-learn-passwords \
--enable-relay-clear-minutes=240 \
--enable-ip-alias-domains=y
