I'm seeing a lot of spam with this in the headers:
PowerMTA(TM) v3.0c2
Is powerMTA mainly a spam tool or do legitimate mailers use it too? Just
trying to decide if I can add some weight if that header exists.
Also of late I'm seeing a lot of spam containing ssl in part of the domain
name:
Dave,
A lot of the largest static spammer organizations use this software, but
unfortunately a good number of fully legitimate companies use it also.
PowerMTA also allows for full customization of the header formating and
many spammers edit this to be nondescript as well. I would guess that
