I am running postfix in Debian Wheezy as my MTA. I currently have it configured to require secure connections for SMTP.
In main.cf I have:
smtpd_tls_auth_only = yes smtpd_tls_security_level = encrypt
And then in master.cf, I have:
smtp inet n - - - - smtpd -o smtpd_enforce_tls=yes
This works fine. However, I have a scenario where I need to allow a single email account access to connect without SSL/TLS due to hardware incompatibility. Is there an easy way to make this requirement selective based on the authenticated user? I haven't been able to come across any easy or elegant solutions to accomplish this.
Any thoughts/feedback welcome!
