At 14:02 2003-04-19 +0100, Obantec Support did say:
i guess what i am saying is i only want mark(_at_)obantec(_dot_)co(_dot_)uk in
the To: to be
valid and not work with @mail.obantec.co.uk
I'm going to assume you mean (any address)@mail.obantec.co.uk would be invalid.
Return-Path: <8bmotv(_at_)yahoo(_dot_)com>
FTR, you can increase the spammishness of messages which have a freemail
return address but NOT a freemail From:
Received: from mail.obantec.co.uk ([212.22.95.2])
by relay.obantec.net (8.12.6/8.12.6) with SMTP id h3JBcO2m004829
There's exists the possibility for a spammishness test with the above
header - an IP address within parens without a hostname means that the
submitting host had no rDNS. Checking forward resolution (manually), I see
that this IP address is NOT what mail.obantec.co.uk resolves to.
* ^Received:.*\(\[[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+\]\)\>+by\>+\
relay\.obantec\.net
A run of this recipe on my own mail reveals a couple of sources of legit
mail which trips up on it: Microsoft developer newsletters, and a firm
which produces security dongles. However, beyond that it's all, spam spam
spam spam spam.
I wouldn't flag this as surefire spam, but it certainly has a "spammish"
quality. Anyway, nothing to do with your request, but there it is.
From: "8bmotv(_at_)mail(_dot_)obantec(_dot_)co(_dot_)uk"
<8bmotv(_at_)mail(_dot_)obantec(_dot_)co(_dot_)uk>
To: Insomn <insomnia(_at_)mail(_dot_)obantec(_dot_)co(_dot_)uk>
Well, if you simply want to trash messages which are have a recipient
identified at mail.obantec.co.uk, then:
:0:
* ^TO(_at_)mail\(_dot_)obantec\(_dot_)co\(_dot_)uk
spamfile.mbx
If you just want the To and Cc headers checked, then:
:0:
* ^(To|Cc):(_dot_)*(_at_)mail\(_dot_)obantec\(_dot_)co\(_dot_)uk
spamfile.mbx
From your earlier post, it sounded as if you wanted some dynamix method to
check for valid versus invalid addressees.
The above is basically the method I described at the foot of a post a few
days ago - use a mail server hostname which isn't itself the hostname which
is used for mail addresses.

I dunno if you care about certain foreign character sets, but a few months
ago, I posted a rather extensive character set recipe, with character sets
grouped by language classification. You can find it at:
