Yes, I'm still using 1.6.x. ;-) However, I'm encountering a weird problem. I seem to be getting duplicate messages, despite the fact that I'm using duplicate delivery supression. I'm using postfix for smtp, and I'm sure I have the duplicate delivery supression on because my Sieve scripts are working. I've also checked /var/imap/deliverdb and the files are definitely updating (although some haven't updated since I last did an install). Heck, one of the files has grown to over 5MB is size! The simple case where I've been getting duplicates has been a small mailing list I setup by simply adding some entries to /etc/aliases. Some people send to both the list and my personal address, and when that happens I get two copies of the message, despite the fact that they both have the same message ID. Does anyone have any ideas as to what I've done wrong? --Chris
