  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.

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

Xav2c

Basic Pleskian
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
 
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.
