Hi, There was a mini-flamewar a while back about this. (I would agree that the current rmail is largely bogus, by the way...) It is possible to cause much grief with modes other than -odq with rmail, particularly if one is unfortunate enough to get several uuxqt sessions going and you suddenly have a dozen sendmails concurrently trying to hog system resources. Even -odq suffers from this a little bit. HOWEVER, if you have a reasonably fast machine, and have your UUCP set up in a Sendmail-cooperative manner (max-uuxqts 1 or 2), you're probably gonna be okay even if you increase the stress levels by using -odi or whatever. You can still blow the living honkers out of a slow machine, or a machine without much in terms of VM resources, but it appears that this is harder to do on the average than it was five years ago. I played for a while on a 386DX/40 with 16MB RAM and generous amounts of swap and had a tough time getting it to kill the system. I think the conclusion I drew from all of it was that it is probably wise to assume the least common denominator - -odq - but it would be REAL nice for many people to be able to specify something else. Perhaps /etc/rmail.config? :-) *I'D* like an rmail which can deal with an RFC822 formatted message, without all the From line crud. I've been hacking around this myself. ...
