Hi all,
I imagine it's more of an implementation robustness issue to support multiline
greetings given the current text of RFC 5321. However, Postfix's new
postscreen daemon, docs http://www.postfix.org/postscreen.8.html , seems to be
relying on it to do its job. Also does something else disturbing (in typical
Postfix experimental fashion) which is to disconnect clients just for not
liking the initial "Teaser" banner. According to the STANDARDS section, this
is RFC 5321-stipulated stuff. According to my experience, yeah, probably works
for short enough timeouts, and I've seen plenty multiline greetings in the wild
...
I don't like spam either, but does this not strike others as being really quite
dangerous thinking and uncertain games to be playing?
Cheers,
Sabahattin
