Data format error This is one of 3 or 4 different broken MAIL FROM:<> rejections I see commonly. Interestingly enough, that host claims to be running Sendmail 8.9.1, which indicates that this one was intentionally self-inflicted (as opposed to sites running packages that inflict this by vendor choice). What I did was: 1) Coded up a standard form letter, explaining what they were doing wrong, why it was wrong, and what problems it caused. 2) If I see one, I send the form letter for the first 2-3 times around. 3) If they keep doing it, they get added to one of my procmail filters so further bounces get dropped on the floor. I've been averaging some 600+ mail/day the last few weeks, so automation is of the essence.. ;) Valdis Kletnieks Operating Systems Analyst Virginia Tech
