Hi, > What did you have to change to get qmail-smtpd to auth through vchkpw?
Make the end of your qmail-smtpd run script look like: ..... \ /var/qmail/bin/qmail-smtpd example.com \ /home/vpopmail/bin/vchkpw /bin/true 2>&1 This will allow any valid vpopmail user to use their email address and password as an SMTP login. Cheers, Jonathan
