What I'd like to see in is an expansion variable that contains the text
of the error message returned from the remote system.
I find that many sites (although not all of course) issue an error message
that could be used to detect rejections due to the null sender.
For example, I'd like to do something like this:
deny !verify = sender/callout=20s,defer_ok,random
condition = ${if eq {$sender_verify_failure} {recipient}}
condition = ${if match {$SENDER_VERIFY_RESULT} {\N(<>|null|bogus from)\N} {0} {1}}
So that callouts that fail with an error message that refers to "<>" or
to "null", etc. are ignored.
Or does such a variable exist?
