I'm new to PMG, been using it for only 3 days now. Quite satisfied too! But the past days I always manually went to Spam Dector > Status > Update Now in order to update the spamassassin rules. Today I didn't do it manually and it still didn't update automatically. For clamav there's a freshclam service in administration > services but for sa-update there is none? So is pmg supposed to update automatically or should I crontab the sa-update process myself?
