You have to use a real domain to set your reverse DNS.

My postfix sends to yahoo fine :/

My postfix sends fine to Yahoo, Hotmail, Gmail, you name it.

I think mileage varies...

From various forum posts over time, it seems like it's a bit hit or miss. Some people have no problems and others have tons of problems, even with correct mail server DNS information, setting up SPF or specific processes for the target service. Yahoo and Hotmail seem to be the most likely to bounce or declare mail as spam.

I've certainly seen posts by folks who appear to have done everything right and still have problems that if I were trying to set it up, I might well be cautious enough to try to use some other service before running my own.

You guys are lucky. do you have a secret to your sucess? It might be that your IPs somehow got whitelisted (maybe by the former IP holder?).

Back when I was trying to get the kinks worked out, I had a conversation with a yahoo rep. He confirmed that my email was properly configured, and that I was not blacklisted, but that the problem was they use a "whitelist" which my IP was not on. I asked how I could get on there, and he basically told me I couldn't.

I have no problems with gmail, hotmail or live. Most small providers accept my emails. I have never gotten them to work with yahoo though. Directly to spam every. single. time. I have both domainkeys and dkim running, reverse DNS, SPF, you name it. I finally gave up.

Also, regarding Yahoo using a "whitelist" to deliver email. WTF kind of a backasswards policy is that?? Did someone throw their hands up and say, "This spam problem is hard -- let's give up?" (And yes, in case it is not apparent, Yahoo's process left me a bit jaded with them.)

I did have some issue with hotmail and yahoo wayyyyy back when, my emails are normally account verification emails, I found that by stripping the http:// part from a link it stopped emails going to spam, why? No idea and does it matter, not really since most if not all email clients will make the address a link without the http://

run

and it'll show what else is listening on port 25.

Alright postfix should say "master" instead of "sendmail" so it looks like you have two email servers, try running

apt-get remove exim4-daemon-light exim4-daemon-heavy citadel-suite

that will remove the common ones people use and leave postfix, then try restarting postfix.

what does

ps -fp 27120

output
