Gary and Sam,

Thanks for the useful info! I have SpamDyke running now with the simple conf and will start looking at the options. I have some white & black lists to import to . .


BTW, it appears top-posting is OK here?

Regards,

Phil.

I'm not familiar with GreyLite at all, but "connection-time" means

This is as opposed to filtering messages in the mail queue, after the
remote server is no longer connected (and believes the message has
been delivered). The advantage of a connection-time filter is the
remote server sees the rejection and the spam is never stored on your
server at all. Rejecting messages after they've been queued requires
either sending a bounce message or delivering it to a user's "Junk"
folder.

This distinction comes up a lot around qmail regarding recipient
validation. By itself, qmail does not validate recipients when
messages are accepted. Any username at a valid domain is accepted,
then bounced later if the address turns out to be invalid. This leads
to the problem of "backscatter spam" -- spammers deliberately send
messages to invalid addresses and set the "from" address to their
intended target. A qmail server will bounce the message (complete with
spam or virus) to the victim. For qmail to validate recipients at
connection time requires a patch or a filter like spamdyke.

People,

I have been using GreyLite for many years but it hasn't been
supported for quite a while - I think it is time to update to
SpamDyke . . but I have some questions - first one:

I looked at the SpamDyke web site and it is still not clear to me -
it says '"connection-time" means spamdyke evaluates and rejects spam
while the remote server is still delivering it' - does this mean it
does it at the TCP / mail envelope level? ie so it would be the same
as GreyLite? GL blocks and forces possibly bad mails to be resent
some time later which many spammers don't attempt . .

Thanks,

Phil.
