Recipient Verification with Aliases

We have users with extra email aliases attached to their Microsoft Exchange accounts. I had LDAP authentication profile selected with Recipient Verification enabled  and discovered due to a user complaint that all of the emails destined to one of these attached aliases were automatically rejected. I changed the authentication method to SMTP and now it seems that any email to our @domain.com is accepted and everything else is rejected. I am pretty sure that this is not the work of the recipient verification feature but actually the recipient policy I have in place.

 

Will recipient verification work correctly with attached aliases? How do I get recipient verification working via SMTP/ESMTP?

Hmm

 

You have the fortimail as a server or gateway?

 

suggestion

 

Could you place a recipient rule with the alias b4  the  LDAP profile rule ( not ideal ) for temp and review the following;

Set the above query , and when you conduct the recipient lookup  does it fail with the alias ?

Thanks for your reply. Yes my fortimail is setup in gateway mode in a DMZ. I setup another LDAP profile using the suggested instructions. The LDAP lookup passed using the alias but the recipient verification fails and an NDR is sent.

After trying several query filters I still get the same 550 error when sending an email to an alias.

 

I have tried:

mail

proxyAddresses=smtp:$m

member

(&(objectClass=Group)(proxyAddresses=smtp:$m))

subtree

never
