We are a small ISP and currently having a mail server (InterMail) serving POP3/SMTP access to our subscribers. Let's say mail system A= serverA.domain.com.my and user e-mail address like [EMAIL PROTECTED] We planning to migate from this mail system to qmail. And we already setup FreeBSD+qmail+vpopmail+sqwebmail+qmailadmin to provide the same service POP3/SMTP Let's say mail system B = serverBdomain.com.my and user e-mail address like [EMAIL PROTECTED] For co-existant purpose (migration) , Is there a POP3 and SMTP proxy solution such that userA POP3 and SMTP access will still poiting to serverA and qmail user (userB) will poiting to serverB ? Note : Both server having the same e-mail domain name. Thanks,
