Hey Hans, Need a little more info to tell for sure what's happening, like whether the messages was coming from an outside server, or from a local client. I'll go with your local client presumption, and also assume they're using Outlook. When Outlook submits a message, it must wait for the server to scan the message before the submission completes. If your server is under a heavy load when a user submits a particularly large email, this might take a couple minutes. The user doesn't notice this, as Outlook is sending from its Outbox in the background. Outlook times out after 1 minute by default, and if the server takes longer than that, Outlook obligingly sends the message again a little later. To fix this problem, increase Outlook's timeout setting. I do this on all Outlook clients. FWIW I also configure them to use port 587, so spamdyke doesn't come into play. ;) If this doesn't fix your problem, then I would guess that your server is under heavy load at times and is taking a long time to scan messages. If that's the case, you can remedy the situation by increasing the timeout setting to 300 or so. A better solution though would be to speed up scanning by putting the simscan working directory on a tmpfs (ram drive). Jake has a howto video on this at http://videos.qmailtoaster.com. I think that one's free, but I'm not sure. I expect that one or both of these solutions will solve your problem. P.S. If you're so inclined, please consider writing a FAQ about this on the qmailtoaster wiki. ;) -- -Eric 'shubes' _______________________________________________ spamdyke-users mailing list spamdyke-users@spamdyke.org http://www.spamdyke.org/mailman/listinfo/spamdyke-users
