Mail best practices?

["Deepak Jain" <deepak () ai net>]

Without going to a dedicated list for something like this, I'm looking for a
common sense approach.

outmail016.ash2.facebook.com [66.220.155.150] due to pre-greeting traffic

 

Sep  3 17:55:22 XXX sendmail[156]: r83Lsg6N000156: rejecting commands from
outmail015.ash2.facebook.com [66.220.155.149] due to pre-greeting traffic

 

Isn't this sort of thing supposed to be frowned upon still? I am not trying
to name & shame here, but I figured this is a pretty big/respectable email
sender.

 

Thoughts for balancing sensible network spam management with sensible best
practices that affect lots of users?

 

Thanks in advance,
