Sun Messaging Server 7.0 MTA config
Hi
I have a cu with below email setup :
Sun Frontend Server running MTA ,UWC/IWC,POSTIFIX & IMSS. ! Backend Message Store Server running Sun Java Messaging Server 7.x & Directory Server 5.x .
All mails are delivered to Mail store over lmtp on port 225.
On FE MTA config Channels configured are tcp_local,tcp_intranet,tcp_auth,tcp_submit & tcp_avas.
TCP AVAS channel is for routing emails to IMSS via POSTFIX (on Port 2025) for Anti-Spam & Anti-Virus scanning.
TCP_AVAS delivers mail to MTA on port 20025.
Customer has purchased new Server & installed New IMSS s/w called IMSVA on this Server. Now the requirement is to make this IMSVA host as Primary MTA & route all Incoming/Outgoing emails via IMSVA server. But all the email within Cu domain (i.e Intranet channel) should first go to Sun MTA (As Sun MTA will do authentication) & get routed to IMSVA server on port 2025 via tcp_avas channel & tcp_avas will re-route the emails after scanning to Sun MTA on port 20025 for mail delivery to Mail Store.
