Postfix+Cyrusでメールサーバを運用しておりましたが、新メールサーバのDevecotを使っての

構築テストです。Version 2.0.21

Dovecotをsslを使用しない設定で起動させると以下のエラーを吐く

doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:93: protocol { ssl_listen } has been replaced by service { inet_listener { address } }

/etc/dovecot/dovecot.conf

”ssl_listen = *”をコメントアウトすると起動しました。特に他の設定いじらなくても良いようです。

/etc/dovecot/conf.d/10-mail.conf

mail_location = maildir:~/Maildir

これでpop3受信の確認が出来ました

しかし・・・saslauthデーモンを起動させたとたん
