SMTP 502 5.5.2 Error: command not recognized

Hi,
I am seeing an SMTP error when sending mail via telnet to the mailsac installation:

[vagrant@vagrant-centos ~]$ telnet 127.0.0.1 25

Is this still an issue @adamlazz ?

[adamlazz]

Yes, because mailsac is still using version 0.3.35 of simplesmtp. The error is related to the way simplesmtp handles blank lines. There are missing cases for \n and \r\n. This module is deprecated, so I don't suppose we will see a fix for this any time soon.

⭐-ed, looking forward to see a solution.

Perhaps updating dependency helps?
