Re: But...

If you're hosting that mail server on a residential connection with no RDNS, chances are that a goodly portion of your mail is going right into spam folders. Many RBLs treat any mail coming from known DSL or cable IP ranges as being sent by known spammers by default.

We are on a business DSL connection, but the ranges are different from residential. I was merely pointing out that reverse DNS wasn't necessary.

I get a good mix of sent to spam and not. I don't do any high volume, so once I send a message if a friend doesn't get it I tell them to check the spam, they hit allow once and I'm good.

Most times however I don't have an issue using it.

Most mail servers will check for forward/reverse DNS pairings. I would highly recommend that you run your mail server with them, doing so is irresponsible:

To receive mail, no. To send mail, almost certainly YES. And depending on how restrictive (read: paranoid) the receiver is, your "in a dialup dynamic residential pool" address may be banned.

More to the point, AOL and my domain mail servers categorically reject email from addresses which have no PTR record. I don't even care if the forward and reverse lookups don't match; virtually any respectable operation will put at least SOMETHING there for a PTR record. Too much spam eminates from addresses where this isn't the case that I rarely make an exception for this. (Although there are around 30 in an exception table I had to create.) I 4xx any such attempts, and only add an exception if I can verifiably determine whether I want email from you.

English is a difficult enough language to interpret correctly when its rules are followed, let alone when a writer chooses not to follow those rules.

Jeopardy! replies and randomcaps REALLY suck!
