I personally think many, many mail servers will block any mail with
X-Mailer containing PHP. Purely because there are an insane number
of chances that its going to be spam.
This is purely based on my opinion though, I'd expect others on the
list to share it or be similar in viewpoint though.
I'd personally not use that header. That is of course just my two
cents though!
Scott.
Speaking as someone who runs a mail server, I don't specifically look
for that kind of stuff... I have RBL lists, greylisting/delaying,
Penalty Boxes, and a content scanner which I don't have active right
now.
I look more for forged helo's, and rbl failures to block my spam...
Surprisingly, about 80 percent of my spam is simply blocked by
greylisting... Easy and simple :) All you have to do to beat it, is
try and resend the mail which mail servers do automatically anyway if
they are setup right :)
But that's just me... If you want some real info on it, I'd suggest
the postfix mailing list. Lots of people on there, and lots of people
at big companies there looking for stuff.
