I wanted to ask: Does this server also store local mail, or is it a gateway? If it also acts as your LDA, there may be some benefit to a separate server for amavisd. I'm thinking in terms of disk activity (with 4GB RAM, using tmpfs may provide some benefit) http://www.stahl.bau.tu-bs.de/~hildeb/postfix/amavisd_tmpfs.shtml I would spend some time insuring SpamAssassin is optomized, stuff like using SQL for Bayes (and AWL), setting up a cron job for expiry rather that letting Bayes auto expire during busy periods, possibly disabling AWL (the database can get huge) or at least create a cron job to trim it down every so often, keep custom rule sets to a minimum etc. Familiarize yourself with: bayes_journal_max_size bayes_expiry_max_db_size bayes_auto_expire bayes_learn_to_journal lock_method (and all the other configuration settings for that matter) Search for or post SA optimization questions on the SA Talk mailing list. I believe with this volume of mail, it would be polite (and more efficient) to run your own local DCC server, and I think that in a commercial environment the license would require you to flood your data to the main DCC servers. I'm not familiar enough with DCC to expound further on that subject, but I think that's generally how it works. If you have money, you could set up 2 remote machines (the only difference could be hostname and IP address), then if one crashes, you could simply change the content_filter IP address in Postfix, and requeue the mail. This would isolate the spam/virus filter and would make the system as a whole less stressful to maintain (and would add redundancy and increased performance). But this is for those with some change in their pockets. If you are trying to save some cash by getting it all on one machine, there is nothing wrong with that approach. This would be called optimizing your wallet. Gary V ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
