Use the following: mail.rollernet.us 67.118.43.92 mail2.rollernet.us 69.111.250.84 The reason I don't recommend doing this is sometime this year I may have to change IP addresses if the office I'm looking at to build a new operations center works out. It just so happens that the office is in a diffe...

Yes, the sender would get a bounce. I usually check the openrbl.org lookups on the mail servers at least once a day to make sure nothing bad is happening. Although there's nothing I can do about what happened, I do have a few ideas to make the mail servers hold messages instead of rejecting them if ...

The retry interval is a sliding scale to prevent the entire queue from being deliverd in large bursts. The inital delay is 15 minutes. If it fails, that time is increased. On each successive retry the time between retries is increated to a maximum of 24 hours. So if a server has been down for a whil...

I'm curious whether the spammer chooses to send mail to the backup mx (is that possible - even if the primary mx is running?), because it may be less likely to filter from ORDB, spamhaus, etc. (i have not set up this filtering yet on rollernet, but i have on the primary mx - this is my fault). That...

Everything looks normal right now - are you still having a problem? One of the servers (mail2/ns2) is somewhat overloaded and keeps running out of memory; replacements are on order and should be here next week or the week after. Although that shouldn't have affected the rest of the system, I'll take...

Historically, BIND has had security issues which prompt installations as a non-root user. The BIND 9 series is a rewrite which much better security than its predecessors, but its reputation remains. That said, it's never a bad idea to run major services like DNS in a sandbox or jail to limit impact ...

DomainKeys
I'm going to look into implementing a DomainKeys filter option. This will be low priority for now, as I have a lot of work to finish on the current track of new features and various updates. You can find more information on DomainKeys at: http://antispam.yahoo.com/domainkeys

If you are using blacklists on your mail server, but don't have them set up in the account manager, a common tactic of spammers is to try the other MX hosts if any of them reject the connection. Right now there's support for DNSBL (i.e. spamcop, SORBS, Spamhaus, etc.) and SPF. Coming soon is Greylis...
