hello SIMS-folks, long time since I've been *here*.
So what brings my here? From looking at the �Queue� it does seem as my server has (attemtedly) been misused by someone for some time. I should have acted more resolute earlier, but now I need to take steps in order to not get blacklisted here and there. Currently I quite often get messages like this:
Failed to deliver your message to [EMAIL PROTECTED]: SMTP: Address rejected by host Host 'mailgw.ntnu.no' says: 554 Service unavailable; Client host [80.111.38.139] blocked using rbl-plus.mail-abuse.org
Gradually --before getting these messages-- I have tried to increase security a little. But after having turned on �Require APOP� in all accounts, �Relay for Clients only� in SMTP-settings (a setting I've almost always have used) as well as �Verify Return Paths� I have reached my level of competense. The only thing I understand is that I need to do take further steps.
First, make sure you're using one of the 1.8 versions. The latest that I know of is 1.8b9d14.
I have three questions therefore:
How do I use �RBL Server List�
Enter one or more RBLs in the list, like this:
cbl.abuseat.org dul.dnsbl.sorbs.net sbl.spamhaus.org relays.ordb.org opm.blitzed.org
these are the ones I use. They currently reject around 80-85% of the attempts to deliver mail to our server. Your milage may vary.
Actually, in the event that anyone actually will ever read the bounce message, I make my entries like this:
cbl.abuseat.org "See: <http://cbl.abuseat.org/> Your mail to greenbuilder.com or one of its hosted domains was sent through a mail server that has been blacklisted for mail abuse."
How does one with ease and efficency use �Black listed�?
If you find that a particular IP address (or range of addresses) is still delivering spam around your RBLs, you can enter the IP address(es) in the blacklist manually:
xxx.yyy.zzz.23
or
xxx.yyy.zzz.1-255
and not least important: how do I stop being blocked from rbl-plus.mail-abuse.org?
Go to mail-abuse.org and re-test your server. See what they have to say about why you were blocked and how to get off their list. Each RBL is a little different. -- Bill Christensen http://greenbuilder.com/contact/
