Hi!
Who's using spam traps in DSPAM?
And how are you doing it with the SMTP?!!
I want to do it but I don't know how :(
spam traps are not a simple thing. if spammers can guess your spam
traps, they can poison them directly, or they can use them as a forged
sender address to other people (think of subscribing them to
lists/groups/...). if they are not protected, honest usrs may send
mail to. ... etc.
That will depend on your action after mail is sent to the spamtrap
addresses...
If you choose to perform sender blacklisting, then i'm positive you'll
have trouble, since sender forgery is a) easy to do and b) one of
spammers approaches to get spam to the recipients.
In other hand, if you choose to blacklist the ip address of the sending
party, you won't have to worry about about a) or b). Still there's a
chance that a spammer uses the same smtp server to send messages as a
legitimate correspondent of some of your users. But even if that's the
case, i'd be willing to take the chance, and put that responsability on
the system administrator of that same server. For those cases that
you're sure that you will just have to accept mail from, like gmail,
yahoo and the like, you will always have whitelisting possibilities.
