Thanks for keeping at this.

One comment:

This is a workaround for a nominal defect.

As such, I think the code should be commented
to note why it exists.

How about adding a comment like:

 		if (defined $smtp_authuser) {
			# Workaround AUTH PLAIN/LOGIN interaction defect
			# with Authen::SASL::Cyrus
			eval {
				require Authen::SASL;
