Find MMP Version

From MsgServerDocWiki

How can I find out the version of the MMP that I am running?

For Messaging Server 6.0 and later, the MMP version will match the MTA version (imsimta version), and will be recorded in the MMP's service log file at "notice" log level. For versions prior to 6.0, the following advice applies:

In non-SSL environments, use telnet to view the banner message containing the MMP version number:

# telnet 0 110
Trying 0.0.0.0...
Connected to 0.
Escape character is '^]'.
+OK Messaging Multiplexor (iPlanet Messaging Server 5.2 HotFix 2.05 (built Mar 3 2005))

In SSL environments, you have to use openssl instead of telnet. For example:

openssl s_client -connect host.domain:993
