Messaging Server Front End / Back End Configuration
I have the following setup:
Front End
-
MMP, MTA, Webmail, UWC
Back End
-
MTA, Message Store
I checked MMP, MTA and Webmail during initial runtime configuration.
1. When the user logins to UWC, the mail tab is missing. It is available only when I set the user's mail host to the backend mail store and not the webmail host. Is this normal?
2. MMP does not seem to work. When Outlook Express connects to the MMP, there is an error in PopProxyAService.cfg
20070702 173828 PopProxyAService.cfg (id 81) server socket IO error: Connection reset by peer (131).
I did not configure anything extra apart from running the initial runtime configuration. What do I need to do to correct the error?
3. I have configure the MTAs between the frontend and backend to use LMTP. However, the message is queued on the tcp_lmtpcs. There is an error in the mail log file.
TCP active open: Failed connect() <client ip> Error: Connection refused
Do I have to explicitly configure the PORT_ACCESS mapping to allow the connection from the front end? The LMTP channel seems to attempt connecting to local LMTP service which does not exisit. Any idea?
Thank you.

The mailhost: is the hostname of where the email is stored a.k.a. the backend. So not only is it normal it is required.

Try turning up the debug logging to 7 in config/PopProxyAService.cfg, restart the MMP (./stop-msg mmp; ./start-msg mmp) and see whether this reveals anything. Also try the following and see how far it gets:
telnet <frontend> 110
user <username>
pass <password>

Was this before or after you changed the users mailhost: setting. Remember that these values will be cached for 15 minutes or so so try restarting the MTA on the frontend & backend and try again (./imsimta restart).
What does the mail.log_current say exactly and does the client_ip you list refer to the IP of the frontend or backend (you say local but local to what?)?
