My ram dos not get full, i do not have so many process, i limit it in postfix.
It reduces the chances of losing emails if i do not have many process of spamassassin runing. So is safe or not to use tmpfs for tempdir in spamassassin. ? This way, everything that spamassassin have to do with the message it does on tmpfs. --- Outside smtp -> postfix -> postfix after queue -> spamassassin -> postfix -> destination Even if SA is going slow, no email will be lost. If it is, something else is broken. If postfix and SA are on the same VM, it's the postfix queue that could be slowing things down. In this case there isn't much you can do as you need postfix to be on persistent media. Also, my understanding is that SA only uses temp files for Razor and DCC checks. Otherwise it should be in ram anyway. Are you doing Razor or DCC?
