Re: Dovecot v.2.2.26

IMAP (Dovecot) seems fine. Any error/warn/fatal message in Postfix log file (/var/log/maillog)?

Re: Dovecot v.2.2.26

Maybe problem with /etc/dovecot/conf.d/10-ssl.conf ?

##
## SSL settings
##

# SSL/TLS support: yes, no, required. <doc/wiki/SSL.txt>
# disable plain pop3 and imap, allowed are only pop3+TLS, pop3s, imap+TLS and imaps
# plain imap and pop3 are still allowed for local connections
ssl = required

# PEM encoded X.509 SSL/TLS certificate and private key. They're opened before
# dropping root privileges, so keep the key file unreadable by anyone but
# root. Included doc/mkcert.sh can be used to easily generate self-signed
# certificate, just make sure to update the domains in dovecot-openssl.cnf
ssl_cert = </etc/pki/dovecot/certs/dovecot.pem
ssl_key = </etc/pki/dovecot/private/dovecot.pem

Re: Dovecot v.2.2.26

With default iRedMail setting, it just uses /etc/dovecot/dovecot.conf, not /etc/dovecot/conf.d/*.
