Unable to open file /etc/dovecot/ssl/dovecot.crt

Dovecot is an open-source IMAP and POP3 server for Unix-like operating systems, written primarily with security in mind.

Dovecot is among the best performing IMAP servers while still supporting the standard mbox and Maildir formats.

It can work with standard mbox, Maildir, and its own native high-performance dbox formats.

It is fully compatible with UW IMAP and Courier IMAP servers’ implementation of them, as well as mail clients accessing the mailboxes directly.

Dovecot also includes a mail delivery agent (called Local delivery agent in Dovecot’s documentation) and an LMTP server, with optional Sieve filtering support.

Dovecot supports a variety of authentication schemas for IMAP, POP and message submission agent (MSA) access, including CRAM-MD5 and the more secure DIGEST-MD5.

Today, let us discuss about the simple workaround given by our Support Techs to resolve it.

The following will allow those emails to be visible in webmail.

[%- IF protocol_imap.imap_capability.defined %]
imap_capability = [% protocol_imap.imap_capability %]
