Actually, no. The sender-blacklist-* and recipient-blacklist-* filters
operate on different data from the header-blacklist-* filters. The
reason is because the sender and recipient addresses are given during
the SMTP protocol and aren't part of the message itself -- the
addresses you see in your mail client are the From and To entries from
the message header. The first paragraph here explains in a little more
detail:

Yes, sorry, I should have realised that . .
Put another way, the sender address doesn't have to match the "From"
address visible in the mail client -- well-behaved mail clients make
them the same, but that's a courtesy and not a requirement. The
Reply-To address is part of the message header and, again, is only a
convention used by well-behaved clients. If you've ever been Bcc'd on
a message, you've seen this in action -- the sender's mail client gave
your address as a recipient but didn't put your address on the "To"
line in the message header.
Right, so, some follow up questions: I moved the following from the
sender-blacklist to the header-blacklist:
@iskysoft.com
- first in the conf file then later into a separate
header-blacklist-file with all the massaged addresses from my old setup
- but the sender above still seems to be getting through. I thought the
"@" was supposed to act like a wild card? Am I still doing something
wrong?
When I add addresses etc to blacklists etc, is there any way of doing a
test myself to see that the block is working? Using a telnet to port 25
on my qmail server and manually pasting header lines is not a real test
is it?
Thanks,
Phil.

I'm not entirely sure I understand your question... if the

address is always the same, you should be able to block it using
the
header blacklist filter.
Ah . . OK - I will try that but doesn't that mean that:
sender-blacklist-entry
is redundant - ie:
header-blacklist-entry
should cover everything?
Thanks,
Phil.
If you're wanting to compare the Reply-To
address to the From address or the sender address, spamdyke
doesn't
have that ability.

People,
One variety of spam that is successfully delivered to me has a
different "From:" addresses but the same "Reply-To:" address - I
can't see a way of blocking these mails in the conf file via the
"Reply-To:" address - is it possible?
Thanks,
Phil.
