additional Mail Addresses

Patrick Ebert

Hello, everyone,

I’m having now  a Sophos SG230 in operation. However, I’m having still few questions:

Some users have several e-mail addresses with us.

givenname.surname@domain.com
surname.givenname@domain.com
Dr.surname.givenname@domain.com

I have noticed that from time to time a mail from Dr.surname.givenname@domain.com ends up in the quarantine report.
For additional email addresses, all email addresses are entered (comes through AD authentication) However, as soon as the user logs in, the optional email address dr.surname.givenname@domain.com disappears from the Webadmin Portal Additional Emailaddress. 
After a prefetch, the e-mail address can be found again under Additional Mail Address.
Is anyone aware of this problem?

 

to better understand what I'm mean, I'll put in some more pictures.

 

Additional Mail Adresse in Exchange

After Prefetch in UTM Admin Portal

 

Mail in Mailmanager

Login in User Portal, I and the User cannot see this Mail

now I looked in the user portal and could determine that dr.surname.givenname is no longer deposited under User/Groups.

 

after a manual prefetch I can see the additional mail address again

 

Where is the Problem?

    Looks to me like you have found a bug.    Suggest you open a case with Sophos Support. 

    Unfortunately, bug fixes take a long time.   To avoid the problem while you are waiting, I suggest disabling any recipient verification.

    With recipient verification disabled, UTM will apply all of its filtering first, before trying to deliver the message.   Known spammers should be blocked with a generic reject message instead of an invalid-recipient message.   This is good because it hinders directory harvesting.   

    When your UTM gets an invalid-recipient result from your mail server, I think that result will still be passed back to the originator, so legitimate senders should still get the information they need for cleaning up mailing lists.   

    I am currently running with verification on, but have wondered if I should turn it off, on the basis of this logic.   As a result, I have no certainty about how UTM handles recipient errors during delivery to the mail server.
