Hi, I followed this How-to: Virtual Users And Domains With Postfix, Courier And MySQL (+ SMTP-AUTH, Quota, SpamAssassin, ClamAV) a while ago and got it working (thanks to some helpful advice ), but now I have noticed that mysql is taking up a lot of memory on our over taxed server and I want to change to using postgres instead. I'd like to keep postfix as it stands and just change the config files so they point to postgres instead of mysql, but I'm not sure if the postfix that I compiled will support this. There seems to be no postgres file in /usr/lib/postfix - how do I enable postgres support? Running Debian sarge BTW Thanks in advance, Matt
