additional Mail addresses/ Old, but noch exist User/ Blacklist Button

Patrick Ebert

Hello, everyone,

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

 

  1. 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?

     

  2. old employees appear in the Mail Manager who no longer exist in the AD.
    They are still receiving emails from Sophos, although these mail addresses are no longer present in Exchange.
    Verified by the following Powershell script: 

    get-recipient -results unlimited | where {$_.emailaddresses -match "user@domain.com"} | select name,emailaddresses,recipienttype  

    Sophos will then try to deliver the mail to the old employee and Exchange will send a mail to do-not-reply@fw-notify.net

    The error Message is  "Remote Server returned '550 5.1.1 RESOLVER.ADR.RecipNotFound; not found'"

    Telnet : 

    MAIL FROM: existuser@***x.com

    250 sender ok

    RCPT TO: notexistuser@***.com

    550 5.1.1 user unknown

    I have also encountered the following link: 

    https://community.sophos.com/products/unified-threat-management/f/general-discussion/21138/quarantine-report-to-old-non-existent-email-users 

    Unfortunately I cannot find a solution here.
    Can anyone help me with that?

 

 

       3. my users also want a button for blacklist and a button to delete in the quarantine report.

           Is there a function that I overlooked in the meantime?

    I don't know UTM internals, but the cause seems pretty evident.

    • You have UTM local user accounts that are linked to backend Active Directory accounts
    • You manually add the alias information into UTM.
    • The user login causes UTM to resync with Active Directory, which does not contain the secondary addresses.
    • UTM overwrites the local user record with the information obtained from Active Directory.

    Based on this scenario, the solution is to add the additional names into Exchange as additional SMTP addresses.

    No, that's not quite right.
    I have the users synchronized via the Active Directory.
    I have opened a new post with pictures for this question.
