I'm quite happy with quotes etc in the local_part. However, where the
domain is being handled by a DNS lookup they are bad news.....
I am currently stripping paired quotes (right round the whole address),
and using my dns patch to kill odd ones left in domains.
I think the DNS problem is actually that the dns.c file converts a number
of various DNS errors into what exim thinks of as a temporary error. In
particular our DNS gives back REFUSED for broken domains:-
pearl{nigel}101> dig "theplanet.net'" mx
; <<>> DiG 2.2 <<>> theplanet.net' mx
;; res options: init recurs defnam dnsrch
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 6
This should maybe be treated as a permanent error rather than a temporary
one.
