Hello,
I have a pretty stock exim configuration with acl_smtp_rcpt acl that
looks like:
acl_check_rcpt:
accept hosts = :
deny local_parts = ^.*[@%!/|]
accept local_parts = postmaster
require verify = sender/callout
[...]
Now if I understand this correctly, the verify sender should check
that the sender is valid, at least from a delivery standpoint. So I'd
imagine that if a message delivery attempt was made from a
non-existant user at a fake domain that the message would get
rejected, but this doesn't appear to be the case for me:
