Oddly enough, jogging my memory with postconf was exactly enough! I noticed that 'permit_sasl_authenticated' was there for 'smtpd_recipient_restrictions', but not for 'smtpd_client_restrictions'. So the blacklist was kicking the connection to port 25, but doesn't care about port 587. I didn't manually edit this during the migration, and don't recall having to add this on the old server. I notice that main.cf is rather sparse for an untouched install, so I suspect Server Admin may have changed in Leopard and does not write it properly when it creates 'smtpd_recipient_restrictions' for the blacklists.
Thanks for the poke!

Since migrating a mail service over to Leopard, I have found that
some users, who are properly using SMTP authentication, are getting

The authentication service is working fine, as many users are
authenticating to port 587. The server is immediately rejecting the
address before there's an opportunity to authenticate. Does anyone
have any pointers as to how that might be fixed?
Can you post the log entries or at least any proof you have that this
is in fact happening. Also post the output of the command 'postconf -
n' so we can see the configuration settings of the mail server.
Without this info it's difficult to help.
