Sendmail acting up

Postby peterg » Mon Apr 30, 2007 4:36 pm

Hello all,

I've installed sendmail on a dedicated server running OpenBSD. I thought it was running ok, but on closer examination that isn't so. I always receive any e-mails that are sent to me, but if I send an e-mail to a hotmail account, for example, it never arrives, even in the spam directory. If, on the other hand, I send an e-mail to my dedicated server e-mail account from hotmail, it arrives, and if I respond to that e-mail my response will arrive at the hotmail account.

What I suspect is happening here is, based on some criteria hotmail is so certain I'm a spammer it doesn't even let my e-mail into the spam folder. If, however, I'm sending an e-mail in response to a message hotmail knows was sent, it'll let the e-mail through.

This is obviously undisarable. Can anyone offer an explanation as to what might be going on here, and the solution?

Hi Peter,

Firstly I checked our name servers and there is no duplicate entires, (we spoke about this offline) But I think I know the problem, Hotmail block messages with no reverse DNS, if you want to tell me the domain you used to configure your mail server I'll set this up.
