It seems like some IPs from Yahoo and Google Groups are listed in ZEN

I hope it won´t block email messages sent by my customers using Outlook and their ADSL connections

It shouldn't block any emails from users who use SMTP Auth. I've never had an authenticated user complain that they were rejected by any blacklist I use. I'm pretty sure authenticated senders are exempt from RBL tests. Don't quote me on that though.

What really happened is that the emails sent to my customers (by their own customers) started to bounce,
because they were detected as spam.

Are you using an alternative port for exim you can give those users?
Home » Service Configuration » Service Manager

I seem to recall this being helpful.

I rarely ever get that problem. If I do, I advise the client that there is a reason why the sending mailserver is on a blacklist and that if that company/person really wants reliable email delivery they would need to contact their mail provider and sort out the reasons for the mailserver being listed.

Admittedly, depending upon where you are in the world, and depending upon the countries that your clientele operate, Zen may be blocking some mail that you consider legitimate. In the states I find it to be pretty darned useful. You may not. You can always look in your mail logs to determine the IP address of the mailserver being blocked and then you can add that IP address into the proper area in the Exim Configuration Manager to exempt that host from RBL checking so that their mail goes through.
