PLAIN Auth

[Matthias Döring]

Hi,

Ich hab da ein kleines Problem.

Alle meine User holen Ihre E-Mails via CRAM-MD5 oder Digest-MD5 ab.

Allerdings muss Ich so eine tolle Software supporten die kann nur PLAIN.
Ach ja TLS kann Sie auch inzwischen :D

Ist es möglich ein Connector zu konfigurieren der PLAIN zulässt,
allerdings sollte nur eine IP-Adresse die Möglichkeit haben so E-Mail
abzuholen. Die Software ist natürlich via VPN angebunden.
