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?
Solved! Go to Solution.

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:
proxyAddresses=smtp:$m
member
(&(objectClass=Group)(proxyAddresses=smtp:$m))
subtree
never
