Sender relay rule SMTPs wrapper mode regression

[DavidePrincipi]

After Mail 1.7.2 update relay rules by sender address cannot send messages with port 465 (SMTPs).

Steps to reproduce

• Configure a relay rule by sender address with port 465 and TLS required
• Send a message with matching sender

Expected behavior

Message is sent out through the expected relay host, with TLS encryption.

Actual behavior

The message stays in the queue, and the following error is written in the log:

Sep 11 10:01:34 ns8 postfix/smtp[74936]: SMTPS wrappermode (TCP port 465) requires setting "smtp_tls_wrappermode = yes", and "smtp_tls_security_level = encrypt" (or stronger)

Components

Mail 1.7.2

Test case

• Check the bug is reproducible with the stable version
• Check the bug is not reproducible with the testing version

Test case verified

• The bug is reproducible with the stable version
• The bug isn't reproducible with the testing version and also sending via port 587 works
