Imo sub addressing are properties of
[email protected][email protected] [email protected] all
3 distinct mail addresses diverging from their sub addresses. We can normalize
them to [email protected] I think the most straightforward is to add the
following methods to MailAddress:```record class SubAddress(String
value)Optional<SubAddress> subAddress();MailAddress normalize();```This should
enable to implement all expected behaviours... A first version of this parsing
could be naïve and ignore comments inside email address, escape sequences,
etc... Also we may have to forbid '+' usage in user names, which should likely
be documented in upgrade instructions as a breaking change.Regards,Envoyé

James Hi Benoit,thank you for confirming my observation. Indeed, it seems quite
extensive.I was wondering if we shouldn't adjust org.apache.james.core.Username
API and make a distinction between localpart (so username+subaddress) and
actuall username (i.e. `username` without subaddress part. Or have another way
to distinguish username in the system from email address?WojtekOn 06/10/2023
