--- Comment #24 from zless <k...@dmesg.site> --- Strange, this might indicate some configuration error on my side. However, I tested the same postfix server with 3 email clients: KMail, Sylpheed and K9-Mail on Android. KMail is the only one that has these postfix logs: postfix/submission/smtpd[18455]: Anonymous TLS connection [...]: TLSv1 with cipher ECDHE-RSA-AES128-SHA (128/128 bits) The other clients show this: postfix/submission/smtpd[18455]: Anonymous TLS connection [...]: TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits) This is for SMTP with STARTTLS. The IMAP connections are using TLSv1.2 as expected. -- You are receiving this mail because: You are the assignee for the bug.
