Open Relay Crap


Well, my ISP has shut me down, saying I have an open relay. My tests through www.abuse.net says I am not relaying. My ISP says I am. They are closed today because of the holiday. Great.

I'm using Postfix, and since I enabled the default IMAP that comes with Red Hat 8 a couple of days ago, it seems I have an open relay. Not sure why enabling IMAP would do that. I swear I didn't make any other changes.

I've tried using the mynetworks parameter in posfix, putting in my IP number only. Still my ISP says I have an open relay. So I'm trying this tactic now:

Quote:
/etc/postfix/main.cf:
smtpd_recipient_restrictions =
permit_mynetworks
check_client_access hash:/etc/postfix/client_access
reject_unauth_destination

/etc/postfix/client_access:
4.3.2.1 OK
5.4.3.2 987654321
But... my mail log says /etc/postfix/client_access.db No such file or directory.
I just created a flat file in that subdir called client_access and put the my IP in it, as sugessed above. How come postfix is not finding that file? Is it supposed to be a different sort of file.. a database file? Not just a flat file? If so, how do I create one? Am I supposed to create it with the .db extension?

Gah this is pissing me off. My friggin ISP...

I am in desparate need of help.

I'm not sure why enabling IMAP would do that. But I'll make a suggestion. Install Webmin it will make the postfix configuration ALOT easier.
Sorry I couldn't be of more help.

However, now I"m getting a lot of rejects. Hrmm... this shouldnt be this difficult.
