lmtp rejecting mails for valid mailboxes

[Daniel Eckl]

Hi!

I don't seem to see lmtp here at all.
Your MTA seems to reject these mails on SMTP layer.

Most probably your MTA can not know which mailboxes cyrus has and that's
why it rejects all mails, because local users are no system user, but by
using cyrus, they are pure virtual. So the mails don't hit lmtp delivery
to cyrus at all.

You should use local_recipient_maps for all users which are in cyrus.
These maps can reside in a file or in a mysql or in an ldap server and
the program which creates new accounts could update this table
automatically. In my case, this is webcyradm who does this for me in mysql.

Best,
Daniel
