As Chris S already said, there's no hard-fast rule here. However, here's a rule of thumb to start with: 1) Use ps aux or top to find the RSS of your largest spamd instance. This will likely be somewhere around 30M, unless you're using some really large add-on sets. If your answer here is over 60M, see my footnotes on reducing memory use. 2) Add an extra 4M to this, to cover extra storage for data. If you're passing -s to spamc, use 16 times the parameter (default is 250k, *16 = 4M). I'm going to pretend my total is 34M. (Yes, I know 16* is generous, but this is a rule-of thumb here) 3) Find out how much free memory you have without spamd running. If you use linux I'd suggest running "free" and look at the free column next to "-/+ buffers/cache:". I'll pretend we have 512M here. 4) Divide the free memory by your answer from 2. That should give you a good rough-estimate number to work with. Footnote on memory usage: If your spamd instances are huge, review the add-on rulesets you're using. Be warry of any add-on rule file that is over 128k in size. In particular, do NOT use sa-blacklist unless you have tons of ram to spare. This ruleset is nearly 2m in .cf file format and will massively expand your SA's memory usage.
