Howdy,

If you restart Postfix, do you see any errors in the mail logs? You can restart Postfix with this command:

/etc/init.d/postfix restart

Hmm, the error “warning: connect to transport private/scan: No such file or directory” is a curious one. Could you paste in the contents of your /etc/postfix/master.cf file? I’m wondering if there’s something in there that’s causing the problem.

That said, it wouldn’t hurt to make sure your server’s IP or network shows up in the “mynetworks” line.

Any chance of some good forum software? I recommend woltlab burning board 4+ Post above looks like a dogs dinner.

Eric · March 17, 2015, 2:09pm

I wrapped the config file above in “code” tags, which makes it look nicer. Joe is working on a migration to Drupal 7 though, which will come with an improved Forum.

Eric · March 17, 2015, 2:13pm

It took me a few looks to notice this, but I think I see what might be causing the problem you’re experiencing… I think it’s related to this line that was added to the Postfix config:

content_filter = scan:127.0.0.1:10025

Try commenting that out, restart Postfix, and see if that resolve the issue for you.

But the emails come to junk mail … Any idea to solce this Problem

Thanks again Eric
I apreciate ur help

Eric · March 17, 2015, 2:59pm

Howdy,

What do you mean by the emails come to junk mail – is it emails being sent to users on your server end up in the spam folder? Or is that emails originating from your server end up in the junk folder on remote systems?

-Eric

szer0p · March 17, 2015, 3:05pm

My vps now can send emails to hotmail but i must go to junk mail to see the email also the hotmail mark this as spam

Can i solve this Problem ?
Thanks

Eric · March 17, 2015, 4:03pm

Howdy,

You may want to verify at a site such as this one that your IP address isn’t listed on an RBL:

http://www.anti-abuse.org/multi-rbl-check/

You’d also want to make sure that you have a reverse DNS record setup for your IP address – that’s something that your ISP would setup for you.

You could also look into setting up SPF or DKIM, both of which can help prevent that.

-Eric

Diabolico · March 18, 2015, 10:06pm

Hotmail, Gmail and many others will automatically mark your email as junk or spam if you miss any of this three options DKIM, SPF and rDNS. This site https://www.unlocktheinbox.com/resources/emailauthentication/ is great if you want to check your email and see if everything is in order. Last but not lease, like Eric suggested check if your domain or IP are on the black list.
