Axigen Mail Server - Users cannot use secure authentication

When connecting to the server using the IMAP or SMTP protocols, users can only connect using plain authentication.

Issue cause

In the AXIGEN configuration file, only "plain" authentication is allowed.

Solution

Edit your AXIGEN configuration file (default: /etc/opt/axigen/axigen.cfg) to allow other types of authentication:


imap = {
  ...
  plainConnAuthTypes = ( plain login cram-md5 )
  # Or you can use the keyword "all" for all of them:
  # plainConnAuthTypes = ( all )
  ...
}

Now reload the AXIGEN server and users will be able to use the secure authentication over IMAP.
The same settings can be applied to the smtpIncoming module.
