There are valid addresses with ! and %
(though only in relayed mail, not for local mailboxes). So:
deny message = Restricted characters in address
domains = +local_domains
local_parts = ^[.] : ^.*[@%!/|]
deny message = Restricted characters in address
domains = !+local_domains
local_parts = ^[./|] : ^.*[@] : ^.*/\\.\\./
But "local_parts" is for testing recipient address (in rcpt ACL).
I don't test localpart of sender address at all.
