    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]>,[]:25, delay=11, delays=0.2/0.06/0.27/10, dsn=5.0.0, status=bounced (host[] said: 550-ATLAS(2504): is blacklisted and not authenticated. Please 550-request delisting via the following link: 550 (in reply to MAIL FROM command))

    Apr 1 15:13:31 galleon34 postfix/qmgr[11312]: 3F24D2235: removed

    the main jist of the error what i can gather is that spamhaus is bouncing my mail, but ive been on the spamhaus site and my IP is not list on any blacklists.

    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

    I did a quick check at this site:

    You are blacklisted on several different lists.

    Result for in LHSBL Blocklists (Alphabetic order):

    You are going to have to use the SMTP servers of your provider to route the mail. It will still show up from you though. It is not a big deal really.

    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 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
