skeight Posted May 3, 2011 Share Posted May 3, 2011 Hi All, I recently started receiving some bounce backs from my web server that sends out emails for multiple domains (shared across multiple clients) due to having a poor reputation. I have gone through the following checklist to make sure that everything was good. 1. Check that it's not an open relay - no problem, don't accept connections on port 25, it's outgoing from webapps only 2. Check for inclusion on any blacklists - no problem, not on any blacklists 3. Ensured that hostname is correct and RDNS is setup - no problem, this was already done 4. Found out about SPF records and added my server as a valid server to send email for the domains in question - *fixed* 5. Checked logs to ensure that none of the webapps were being used to send out bulk spam - fine, no issues that I can see. I should also note that I have two scripts that run that send out emails. 1 is to a small list of about 200 people which includes a weekly report and the second is a monthly newsletter that goes to about 2000 people. There are occasional (1-3 times a month) other press releases and whatnot that get sent out through a newsletter system as well and that can range from 500-5000 people depending on the group that is to receive it. So on to my questions... 1. Would invalid SPF entries cause me to have a poor reputation or am I potentially missing something else? 2. If that was all that was required, how can my reputation be improved when emails are still being blocked because my server has a bad reputation? Any help would be appreciated. I could just route all the email through another server but I would much rather see the reputation of this server go up. Link to comment Share on other sites More sharing options...
