SpamAssassin 2.55 problem

One of the important things to do on small systems is to reduce the
Max Children
setting in MailScanner.conf. This will greatly reduce the memory required.
On a lightly loaded system you probably need only 1 or maybe 2 child
processes. The default of 5 is for systems which have plenty of RAM.
I suggest you give that a try, it may well help.
