Odd: same client, different domains sharing accounts?

[h0t1ce]

Hi,

I have a client that has 2 domains. example: comp1.com and comp2.com

only one account employee@comp1.com was created. But for some reason sending an email to employee@comp2.com (doesn't exist) will send the email to employee@comp1.com.

Is there a setting to prevent this from happening?

thanks for your time

Is the second domain a separate website or is it a co-domain?

[h0t1ce]

Both domains are individual entries in the "sites" folder.

Looking at the 'co-domain' tab for each doesn't show an entry of the other domain either.

Ok, then the domain names are not connected. Have you disblaed username prefixes? If employee is a linux username, then it will catch emails from all domains where the email address starts with employee@.... To prevent that, edit the file /home/admispconfig/ispconfig/lib/config.inc.php and cahnge the line:

$go_info["server"]["postfix_config"] = 1;

to:

$go_info["server"]["postfix_config"] = 2;

then edit the mailbox settings of a user in ispconfig, e.g. change quota and click on save so that the configuration file gets rewritten.

Thanks for the fast reply. Didn't notice your second reply since I didnt get an email alert.

I tried changing the setting then changing the quota of one user in the web frontend to have it regenerate the file.

Now users are getting this email sent to them in large quantities.

See attachment for an example email being received.


thank you

Is localhost.localdomain listed in /etc/hosts?

[h0t1ce]

localhost.localdomain is actually mentioned twice in /etc/hosts. But it's because there's two lines for 127.0.0.1. Which I find a little odd, hopefully that doesn't cause conflict.


127.0.0.1 www.company123.com www localhost.localdomain localhost
10.20.40.122 www.company123.com www
127.0.0.1 localhost.localdomain localhost

I did notice that localhost.localdomain wasn't in /etc/local-host-names
Could that be the problem?

I'm a little worried to bombard my mailboxes with hundreds of the error email again. Is there a way to avoid that message temporarily from being delivered?

thank you so much for your time.

Should be no problem, but nevertheless I'd remove the last line.

Do you mean /etc/postfix/local-host-names? If so, add localhost.localdomain to it (at the end where you are allowed to make modifications) and restart Postfix.
