STARTTLS 500 Unrecognized command

Issue #761 new
Alex created an issue

Hi,

I am getting the 500 Unrecognized command error every other time when I try to send a message on port 587 with version 2.2.19.

[->] STARTTLS
[<-] 500 Unrecognized command

I reverted to 2.1.11 and it seems to be working fine. I haven’t tried any other version. I am having this issue with ssmtp and also the PHPMailer library.

Thanks.

    What is strange is that I have had another instance of version 2.2.19 running elsewhere for a while and it doesn’t seem to have this issue.

    Do you have custom TLS certificate? Haraka usualy don’t advertise STARTTLS when there is problem with certs
