Errors relating to Roundcube email filters

Recently, one of our customers was trying to create a Roundcube email filter and got an error message. Here, is the error message:

Unable to connect to Sieve server

Our Support Engineers started troubleshooting the error by checking the logs from the path /var/log/plesk-roundcube/errors. Since he was using plesk installed server We could find the below error there

ERROR: Connection refused (111)

In Plesk >> Tools & Settings >> Mail Server Settings, Courier-IMAP was shown as installed as the IMAP/POP3 server.

The reason for this error to occur was Courier-IMAP doesn’t support Sieve.

So, we installed dovecot as IMAP/POP3 server.

Log in to Plesk >> Access the Tools & Settings >> Updates and Upgrades >> Add and Remove Product Components >> Mail Hosting and install Dovecot.

Note: Dovecot configuration used by Plesk is compatible with Courier and acts as a drop-in replacement.

Finally, this fixed the error.
