Topic: email sent from sme server not recognized as duplicate

[penguin_bb]

I have a strange problem with the mail server.

I have server A which runs sendmail, server B runs SME server. On server A, I have email aliases setup so a user will not receive duplicate emails. e.g. X's email is forwarded to Y, if I send one email to both X and Y, Y will only receive one single email. It works fine before and even now.

The problem is when I send from server B, Y receives 2 copies instead one 1 now. I tried sending from other server and it is fine, only when I send from B, the duplicated emails are not recognized.

Is there anywhere to config qpsmtpd to amend this problem? Thanks for any input.
