So that won't work. Exim gives up and won't retry ever -- so 450 becomes
essentially an immediate permanent error.
I have been speaking with a qualified person at Bellsouth who has
informed me that certain IP blocks that ATT has identified as sources of
spam are "throttled". The blocks of course are DSL/DHCP addresses, plus
others lumped in there because it makes their lives easier at ATT.
Unfortunately, I'm in one of the other blocks that is static, so I get
the 450 treatment. I have no choice but to resend. It's sort like a
greylist, I guess.
