New 12.5 server refuses pop/imap connections without SSL/TLS

[Xav2c]

Hi,

I just changed my server's provider,and used the migration manager to retreive all my objects to my new server from plesk 12.0 to plesk 12.5

When a mail client tries to connect to any domain name without ssl/tls, i get a popup (in outlook 2016) asking for the username/password.
Even if i enter the correct login info, it keeps asking until i activate SSL auth.
I managed to disable for SMTP commenting this line in /etc/postfix/main.cf : #smtpd_tls_auth_only = yes
So now i can connect using port 25 and plain text auth.

But where can i enable plain text auth for courrier/imap?

Thanks in advance for any help

Hi Trollface,

But where can i enable plain text auth for courrier/imap?

Please have a look at:

Odin / Parallels Plesk Panel for Linux services logs and configuration files ( KB - article: 111 283 )​

You will find there all locations for configuration files, which depend on Plesk related services.

Hey UFHH01! Thank you for your answer

I copied my courrier/imap conf files from the old server :
/etc/courier-imap/imapd
/etc/courier-imap/pop3d

Now it works fine again.
