Not owned by user

[y***@gmail.com]

I think I'm missing a setting somewhere, I've got several domains aliased, and listed in mydestinations, but still get the following error when submitting emails:

The server response was: ***@domain.com: Sender address rejected: not owned by user bob

I'm wondering if I need to run a postmap command rather than postfix reload, or whether I just need an additional param somewhere?

(Debian Wheezy / Dovecot / Postfix / local system passwd authentication)

Dovecot working fine with sasl for imap btw.

reject_sender_login_mismatch - which is nowhere to be found in your config.

smtpd_sender_login_maps is a map, not a list of domains
and the map should look like this:

***@domain.com bob
