That's a bit drastic.  In my case I'm still looking for the reason MS+SA
are slower than normal, but if I turn off SA I may as well turn off MS
too -- without SA, MS catches almost nothing.

I added SBL+XBL at the MTA level and my queue size is now dropping
again.  Shockingly (to me) SBL+XBL is blocking a *very* large percentage
of the inbound connections -- >99% each time I've checked this
afternoon.  No reported false positives yet though (only been running a
few hours) and no one's loaded the web page I put into the SMTP
rejection response -- I'm pleasantly surprised.  Didn't expect it to
catch so much.
