Accepting mail in a catch-all is going to take more resources than refusing the messages with a "User unknown" error. By "DoS", I'm guessing that your server is reaching its maximum number of SMTP sessions? If so, take a look at actual resource utilization. Check the amount of memory and CPU time that the processes are taking, and look at the number of open files. If you still have available resources, then the best thing to do is probably to simply increase the maximum number of connections you'll accept. The defaults are extremely conservative. Most servers can handle considerably more. ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ courier-users mailing list [email protected] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
