I've noticed recently some messages I haven't seen before in the logs:
qualify/rewrite: address is ridiculously long
I do agree with the sentiment (looking at one, the Reply-To address was an
absurd 331 characters long), but slightly unclear if it's indicating that
Exim's behaviour is changed as a consequence, or is this it intended merely as
a general observation?
The code has been there since 4.95 (released Sept 2021), with a limit of 256
chars.
The limit derives from RFC 5321, according to the comment in the code.
Before then the same test and message was there, testing against 512 and
referrring
to an older standard.
