Hello,

I've been trying to get the imap AUTH PLAIN login method enabled using the "Enable clear text login" in the admin panel; but failed to use the PLAIN method over an Imap connection port 143 and even using an SSL conection to port 993.

A friend suggested to confirm the capabilities of the imap server using telnet to por 143 but no PLAIN option is listed:

$ telnet <myserver> 143
1 OK [CAPABILITY IMAP4rev1 ACL BINARY CATENATE CHILDREN CONDSTORE ENABLE ESEARCH ESORT I18NLEVEL=1 ID IDLE LIST-EXTENDED LIST-STATUS LITERAL+ LOGIN-REFERRALS MULTIAPPEND NAMESPACE QRESYNC QUOTA RIGHTS=ektx SASL-IR SEARCHRES SORT THREAD=ORDEREDSUBJECT UIDPLUS UNSELECT WITHIN XLIST] LOGIN completed


Does anyone have a clue what am I doing wrong?

Regards,
Ivan Teran

Here I post the zmprov config:
