- Plesk Onyx for Linux
When trying to set up an IMAP account in Outlook or Samsung Email android app, IMAP option is not available in the "Account type" field:
One of the following errors can be found in
/var/log/maillogon Plesk server:
CONFIG_TEXT: server dovecot: imap-login: Disconnected: Inactivity during authentication (client didn't finish SASL auth, waited 179 secs): user=<>, method=DIGEST-MD5, rip=127.0.0.1, lip=127.0.0.1, TLS, session=<Uzcj+sRVW+J/AAAB></>
CONFIG_TEXT: imap-login: Disconnected (auth failed... The issue is not reproduced in other mail clients, like Thunderbird.
CONFIG_TEXT: SASL DIGEST-MD5 authentication failed: authentication failure
Current implementation of a DIGEST-MD5 authentication in libsasl2-2 package is incompatible with Microsoft Outlook. Additional details can be found here.
Note: if you don't have root access to Plesk server via SSH, contact your hosting provider regarding the issue
Login to Plesk server over SSH
Create a custom configuration file and place the
auth_mechanismsparameter without digest-md5:
# vi /etc/dovecot/conf.d/00-auth_mechs.conf
CONFIG_TEXT: auth_mechanisms = plain login cram-md5 apop
Restart Dovecot to apply the configuration changes:
# service dovecot restart
