Peter, Please read the RFC822 standard description before starting to criticize what I have done and stating that "RFC822 states that addresses must be case insensitive". This statement is --> WRONG <--. The DOMAIN part, ie everything after the '@' sign must be case insensitive, ok. But the "local-part" of the address, ie what is BEFORE the '@' sign, IS case sensitive. See page 14 of RFC822 STANDARD. I fully agree with the fact that UNIX is shit and is responsible about its stupidity and should manage to get the mail through. I just made the change to LISTSERV because of too many complaints from UNIX people. Jeff: your problem is funny. I don't recall using the LOAD command in LISTSERV, so how the heck can you get a LOADER TABLE OVERFLOW? You might solve it with a SET LDRTBLS 5 in the PROFILE EXEC but the point is I see no reason why you should need that... Oh well.. :-) Eric
