How can I verify if TLS is working for SMTP? I can see when I connect to Dovecot via IMAP4, a TLS session is present but I don't know to configure TLS for SMTP (sending messages). Below is me sending an email from my server outbound to an external email address. Obviously the IMAP4 session is TLS but what about SMTP? Code: Apr 5 13:49:29 mail postfix/smtpd[5606]: connect from tuna.iamghost.com[10.1.1.204] Apr 5 13:49:29 mail postfix/smtpd[5606]: [COLOR="Red"][B]setting up TLS connection from tuna.iamghost.com[10.1.1.204][/B][/COLOR] Apr 5 13:49:29 mail postfix/smtpd[5606]: [B][COLOR="Red"]Anonymous TLS connection established from tuna.iamghost.com[10.1.1.204]: SSLv3 with cipher DHE-RSA-AES256-SHA (256/256 bits)[/COLOR][/B] Apr 5 13:49:29 mail postfix/smtpd[5606]: AA96DA53: client=tuna.iamghost.com[10.1.1.204],[COLOR="Red"][B] sasl_method=PLAIN, sasl_username=carlos[/B][/COLOR] Apr 5 13:49:29 mail postfix/cleanup[5608]: AA96DA53: message-id=<[email protected]> Apr 5 13:49:29 mail postfix/qmgr[1132]: AA96DA53: from=<[email protected]>, size=596, nrcpt=1 (queue active) Apr 5 13:49:29 mail postfix/smtpd[5606]: disconnect from tuna.iamghost.com.org[10.1.1.204] Apr 5 13:49:30 mail postfix/pickup[5443]: 1A67FA6C: uid=5001 from=<[email protected]> Apr 5 13:49:30 mail postfix/cleanup[5608]: 1A67FA6C: message-id=<[email protected]> Apr 5 13:49:30 mail postfix/qmgr[1132]: AA96DA53: removed Apr 5 13:49:30 mail postfix/pipe[5609]: AA96DA53: to=<[email protected]>, relay=spamassassin, delay=0.42, delays=0.08/0.01/0/0.34, dsn=2.0.0, status=sent (delivered via spamassassin service) Apr 5 13:49:30 mail postfix/qmgr[1132]: 1A67FA6C: from=<[email protected]>, size=893, nrcpt=1 (queue active) Apr 5 13:49:30 mail postfix/smtp[5613]: 1A67FA6C: to=<[email protected]>, relay=smtp.google.com[209.85.210.99]:25, delay=0.84, delays=0.08/0.01/0.2/0.55, dsn=2.0.0, status=sent (250 2.0.0 OK 127048) Apr 5 13:49:30 mail postfix/qmgr[1132]: 1A67FA6C: removed Apr 5 13:51:28 mail dovecot: IMAP(carlos): Disconnected: Logged out bytes=71/848
