[rt-users] CanonicalizeUserInfo in Email.pm - "Name in use"

[Lars Kristian Klykken]

Hi!

RT 3.8.1 with RT::Authen::ExternalAuth 0.05

We are having an issue where users can have several mailaliases defined,
and where they have different mailaliases depending on what MUA they are
currently using (like webmail).

Users are properly authenticated on the web interface, and they also
have no problem sending mail to RT, as long as they're using the email
address defined in RT at createtime (or modified manually in the
preferences), but as soon as they try to send an email to RT with one of
the LDAP defined aliases (specified as 'mail' objects) it will be
bounced with the reason 'Name in use'.

Any suggestions? It looks to be a bit like this problem:
