Afternoon, im a bit of a newbie to this, Ive im the process of setting up my own mails server, running on Ubuntu Server. with Postfix and Dovecot. I have set up a couple of users accounts and can send emails round my domain (internal), but im unable to send to an external account, although emails from an external account are getting delivered to my test user account. the error message im receiving upon looking at /var/log/mail.log is as follows Apr 1 15:13:30 galleon34 postfix/smtp[11323]: 3F24D2235: to=<[email protected]>, relay=mail.dns21.co.uk[194.154.164.60]:25, delay=11, delays=0.2/0.06/0.27/10, dsn=5.0.0, status=bounced (host mail.dns21.co.uk[194.154.164.60] said: 550-ATLAS(2504): 90.204.127.47 is blacklisted and not authenticated.

As a bit of a newbie to Linux, if anybody has come across this error / or knows how i can sort this out. That would be much appreciated. Many Thanks Chris
I did a quick check at this site: http://www.blacklistalert.org./ You are blacklisted on several different lists.

It will still show up from you though. It is not a big deal really.
You can also set up your email server to relay through a non-blacklisted outside server. http://www.howtoforge.com/how-to-relay-email-on-a-postfix-server I did this from my at home server through my shared hosting server and it worked great. Now I do it through my own not-at-home servers.
Thanks so far thanks dclardy & BorderAmigos for the advice given so far, I've managed to set up postfix to relay though my ISP, but it might seem a silly question. Since ive not re-configured my main.cf to relay though my ISP, the emails are getting received as being sent from my ISP's email account and not my Linux mail server im trying to get up and running. how can i stop this, thus still keeping the email as being sent from my mailserver rather that its being relayed of my ISP SMTP servers. Many Thanks, in advance again Chris
