This appears to be some bad interaction between Listserv and some Listserv-like software on the Internet. The potential for mailing loops is high... Anyone seen this before? I suppose I'm lucky that the "From:" line caused the file to be rejected. Otherwise there could have been a lot of wasted mail traffic. I haven't completely figured out how this happened, since Info-Vax isn't a list we peer at JHUVM, and there is no such e-mail address <E@JHUVM>. Any ideas? -jj ----------------------------Original message---------------------------- Error occured while processing file 3766 from MAILER@JHUVM: "Command mailfile contains invalid RFC822 fields and could not be parsed".
