Hi,
Due to the popularity of OpenSMTPd here, I thought the group might
appreciate that MTA is not affected by the "SMTP smuggling" attack [1]
like the other mail servers. [2]
According to #opensmtpd, our MTA does not support pipelining and is
therefore not vulnerable.
Some additional patches for hardening are being tested but they do not
currently play nice with all others.[3]
Kind regards
Felix
