Steve is fine.

"Why" is sort of my original issue. As I don't generally get timeouts, I was
wondering if something wasn't causing this by these particular emails,
especially since everyone of them receives a timeout.

I have considered it, but have not implemented or really needed it. I guess
that's kind of selfish, using unnecessary bandwidth all the time.

I am using the default SA RBLs + surbl.org. I could consider turning some of
these off if this persists. It seems like there are so many that contribute
such a small amount to the score, that a few less wouldn't make that much
impact on the spam/not spam total.

A luxury we here can't afford, I'm sure.

Again, thank you for the time and efforts.
