Bug 2255.

Apparently not. We thought that disabling the sessions cache on the
IMAP service might help (the supposition is that OE is trying to
re-use the IMAP TLS connection for the SMTP connection, as it only
seems to happen when IMAP is served by the same system) but that
was tried and didn't help.

Being discussed; see Phil's message an hour before yours.

The upcoming 4.91 will revert to leaving the cache uselessly
enabled; any knob will not appear before 4.92.
