You're jumping to conclusions... LISTSERV doesn't really care about the trailing period. I'm sure that if you send an ADD command for [log in to unmask] again, you will find that your password is still there afterwards (at least if it's *literally* 'user3'). Anyway, I haven't been able to reproduce your problem. If you can reproduce it on your machine, please send me the job and I'll try with the exact same data. The question about NTFS was because, as you know, FAT is not a reliable file system. It is not uncommon for NT customers who use FAT to have strange problems that turn out to go away after a CHKDSK.
