Any ideas? > One thing you need to check on when choosing between mysql and postresql is the licensing. postgresql is freely usable. mysql had changed their licensing a while back such that any commercial use of it required a license fee. Not sure if that is still the case but it was earlier this year. Both will most likely do the job. You should really use which ever you are most comfortable with or use in other projects. I have used both but currently use postgresql for my projects. As to your original question, any of the MTAs listed will do the job. Just do the homework and make sure you do not create an open relay. Others have mentioned most of the items you want to use including spamassassin. Another item you will want to add to your setup once you have the basics working is greylisting. greylisting will keep your system from having to process thousands of spam messages since most spammers will not resend messages. The combination of greylisting and spamassassin has reduced spam to virtually zero where we used to get anywhere from 3000 to 6000 spam messages a day. And there were some days where the shear volume of messages was causing the email server load average to spike to over 20 at times as spamassassin tried to handle the load. With greylisting in place this has not happened, I have not seen the load average on the email server go over 2 since that has been implemented. -- Scot L.
