Has anyone been able to get squirrelmail to work since updating to Fedora 21? We have the following roaming configuration: outside web server -> dovecot port 993 -> inside mail server This worked for years before updating to Fedora 21 and we are now running Fedora 22. It fails with the following errors: Jun 14 14:34:34 douglas dovecot[1653]: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=10.2.2.2, lip=10.2.2.7, TLS handshaking: SSL_accept() failed: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca: SSL alert number 48, session=<EkGAG4EY+QAKAgIC> Jun 14 14:40:25 douglas dovecot[1653]: imap-login: Disconnected (no auth attempts in 6 secs): user=<>, rip=10.2.2.2, lip=10.2.2.7, TLS, session=<bdZmMIEY/AAKAgIC> Jun 14 14:44:24 douglas dovecot[1653]: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=10.2.2.2, lip=10.2.2.7, TLS handshaking: SSL_accept() failed: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca: SSL alert number 48, session=<rRCuPoEY/QAKAgIC> It works when testing from the outside web server using Thunderbird: Jun 14 10:06:49 douglas dovecot[1615]: master: Dovecot v2.2.18 starting up for imap, pop3, lmtp (core dumps disabled) Jun 14 14:32:15 douglas dovecot[1653]: imap-login: Login: user=<dhighley>, method=PLAIN, rip=10.2.2.2, lip=10.2.2.7, mpid=5413, TLS, session=<bQY4E4EY5gAKAgIC> Jun 14 14:32:26 douglas dovecot[1653]: imap-login: Login: user=<dhighley>, method=PLAIN, rip=10.2.2.2, lip=10.2.2.7, mpid=5418, TLS, session=<ZcfaE4EY6QAKAgIC> Jun 14 14:32:50 douglas dovecot[1653]: imap-login: Login: user=<dhighley>, method=PLAIN, rip=10.2.2.2, lip=10.2.2.7, mpid=5423, TLS, session=<vWROFYEY7wAKAgIC> Jun 14 14:33:26 douglas dovecot[1653]: imap-login: Login: user=<dhighley>, method=PLAIN, rip=10.2.2.2, lip=10.2.2.7, mpid=5432, TLS, session=<HyxoF4EY8gAKAgIC> Jun 14 14:33:26 douglas dovecot[1653]: imap-login: Login: user=<dhighley>, method=PLAIN, rip=10.2.2.2, lip=10.2.2.7, mpid=5437, TLS, session=<ozt1F4EY8wAKAgIC> The squirrelmail config_local.php file: $org_name = "Highley Recommended, Inc."; $org_logo = SM_PATH .
