hello. currently, part of my spam strategy is to take advantage of the blacklist feature of sendmail*. however, i read somewhere recently (and it made a lot of sense to me) to accept email only sent to valid email addresses and reject the rest. lately i've notied a lot more random usernames being prepended to @swatgear.com. my setup is the following: internet => sendmail w/ spamassassin => exchange 2k can someone tell me what this is called and where i can read a document(s) on how to get it working? thanks, chris. -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
