I thought I should add some other information in this subject. I'm working as a IT-Consultant, lots of NT and Mail.
Several of our small customers has also had the problem with duplicate messages. The common factor was that they used POP3 to fetch mail from a mailbox at their ISP The mail just kept comming at a regular interval (every 15 minutes or so, when the server fetched the mail) This occured on several different mailsystems (Exchange, MDeamon, AMOS Mail) The standard procedure was to telnet to their mailbox at the ISP, check if the top mail in the list was important and the delete it. Once these customers got their direct connection and moved over to standard SMTP received mail the problem disapered. If you want to check out, POP3 commands is listed in RFC1945 (I'think it was). I usualy use: list -> top 1 30 (display the top 30 rows of the first mail) -> del 1 Best regards Hans Birgander ----- Original Message ----- From: "Davide Libenzi" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Saturday, May 25, 2002 12:01 AM Subject: [xmail] Re: duplicate messages (again) > > On Fri, 24 May 2002, Steve Jacobs wrote: > > > > > I've seen this same behavior three times during the last month or so, with the number of dup messages varying from 26 to 84. However, this can't be a bug in XMail 1.8, as I'm still running 1.2 on this machine (RH Linux). Xmail ran for months (since whenever 1.2 was the current version) without spewing duplicates. > > > > Here's what little I know about this: > > > > 1. We're a tiny country ISP with about a hundred users. No reports of duplicate messages from any of them. Some of them are the kind who gleefully report _every_ anomaly, so if this was happening very much I'd hear about it. > > > > 2. There is no record in any Xmail log of these messages being processed more than once, either arriving or departing. Maybe it's my mail client (Sylpheed on RH 7.2 Linux) choking on something? When Sylpheed displays the dups, they are always preceeded by a an empty (completely empty, 0 length, no headers, no nothing) message. > > > > 3.
