EDIT: Okay I'm stupid, I was testing SMTP (submission), for IMAP it seems ok.
However it would be good to also have PLAIN auth for SMTP as it is available for other protocols (pop3/imap).
Hello,
In build 7314 changelog there is this nice new addition:
ADDED: PLAIN SASL support in IMAP.
However we're on build 7342 at the moment and SmarterMail doesn't announce this capability for IMAP:
Here is the test showing it:
$ swaks --to whatever@swisscenter.com --from "sriccio@whatever.com" --header "Subject: Test mail" --body "This is a test mail" --server smbeta.swisscenter.com --port 587 --timeout 40s --auth PLAIN --auth-user "sricciok@whatever.com" --auth-password <redacted> -tls
=== Trying smbeta.swisscenter.com:587...
=== Connected to smbeta.swisscenter.com.

It should announce "AUTH PLAIN LOGIN CRAM-MD5 NTLM"
Kind regards
