When users are deleted from workgroup manager, emails to their email account still go through instead of bouncing back.

 

The same occurs when simply setting the mail setting to "None" instead of "Enabled".

 

I have also deleted the same accounts from Server Admin -> Mail -> Accounts, but problem persists.

 

I have restarted the server - issue persists.

 

Where else could their user record still be stored?

 

I think it's postfix's job to reject these emails..?

 

When I send an email to a jibberish account that has never existed in the past, it is successfully rejected with /var/log/mail.log showing:

<asdfjasdf@mycompany.com>: Recipient address rejected: User unknown in local recipient table;

 

When I email an ex-employee whose account was deleted, email goes through with /var/log/mail.log showing:

Jun 24 08:26:42 ods1 postfix/smtp[28886]: B37F5658CDD: to=<exuser@mycompany.com>, relay=127.0.0.1[127.0.0.1]:10024, delay=0.19, delays=0/0/0/0.18, dsn=2.0.0, status=sent (250 2.0.0 Ok, id=29894-02, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as DE236658CE4)

Any advice greatly appreciated!

    A month later and this issue is still plaguing us.  Anyone out there who has experienced the same or who has any advice as to how to go about troubleshooting this?

    For all those that face a similar issue: it was resolved after demoting Open Directory server to standalone, promoting it back to master, reimporting all users and reentering all passwords - a major pain in the butt, but nothing else would fix it.

     

     

    About a month later, I thought I had the same issue, but luckily this time it came good after a few hours.  I think a postfix reload may have contributed towards getting it successfully rejecting this time:

     

    sudo postfix reload

     

     

     

     

    I'm trying to understand how the Apple Open Directory <> Postfix setup works so that I have a thorough understanding when next faced with this issue.

     

    I believe the relevant line in    /etc/postfix/main.cf   /   postconf -n    is:

     

    local_recipient_maps = proxy:unix:passwd.byname $alias_maps

     

    (http://www.postfix.org/LOCAL_RECIPIENT_README.html)

     

     

     

    I'm not sure what the proxy:unix:password.byname part means, but $alias_maps is defined below:

     

    alias_maps = hash:/etc/aliases,hash:/var/mailman/data/aliases

     

    /etc/aliases has all the postmaster, abuse, etc. entries - none of the actual users' accounts.

    /var/mailman/data/aliases has all the entries for the mailing lists - none of the actual users' accounts.

     

     

     

    This leaves me with either:

    local_recipient_maps not being the correct setting

       or

    The part I don't understand: proxy:unix:passwd.byname being the list of actual mail users

     

     

    Does anyone know the answer?
