[vchkpw] multiple mails
I use vpopmail on qmail. I have many customer domains on that mail server. One of these customer domains tells me that, they rarely receive the same mail a few times. That problem becomes nearly once a week for this customer. I haven't any complain from my other customers. They use outlook or o.express for their mails. What may the problem be ? Do I have to change my configuration ? !DSPAM:4aaa2ee432719078915881!
Re: [vchkpw] multiple mails
Ask them to check for any incoming e-mail scanner running on their local machine. If so, ask them disable the same. Also check the .qmail file in the user's folder for any duplicate entries.

Sometimes a long scan time will cause the sending server to time out before the scan is complete and your server acknowledges receipt. The sending server then obligingly resends. Check the smtp logs for the corresponding duplicate email. You'll see 2 receipts for it if this is what's happening. -- -Eric 'shubes' !DSPAM:4aaa575832712042125807!

Oh, and if this is the problem, I would install spamdyke to lighten the load on your server. It works great. You'll be scanning a lot less email, and filtering more spam at the same time. http://spamdyke.org/. Personally, I'd install spamdyke in any case. You'll be glad you did. -- -Eric 'shubes' !DSPAM:4aaa5a3d32711198235893!
Re: [vchkpw] Re: multiple mails
I checked smtp logs for these mails. But I couldn't see any duplicated mail. What else may the problem be ? - Original Message - From: "Eric Shubert" To: Sent: Friday, September 11, 2009 4:57 PM Subject: [vchkpw] Re: multiple mails Bulend Kolay wrote: I use vpopmail on qmail.

[vchkpw] Re: multiple mails
If the server isn't receiving them twice, then I'd look at the possibility of them being pop'd twice somehow. I don't know how that might happen (all of my Outlook clients are using IMAP). I presume your customers are using pop3. Bulend Kolay wrote: I checked smtp logs for these mails. But I couldn't see any duplicated mail.
