Just wondered if there was a way of making the PLAIN an authentication method for POP3S transactions only without making this an option for IMAP? I am attempting to connect to a POP3S server through the GMail interface available through "Accounts and Import". The issue is that there does not seem to be an option to specify the type of mechanism within their interface so I think I have to offer PLAIN along with SSL. Has anyone else had any experience of using the GMail import settings?

why not simply allow PLAIN at all?

nearly all modern clients are using CRAM-MD5 as default if offered as also SSL/TLS if offered - let your users decide which mech they are using, really, some of them my use whatever sync-tools like imapsync or whatever which should not bother you at all
