I doubt the problem is the lack of a PTR record. If you tried the reverse, "mail from xxx@xxxxxxxxx" to someone@xxxxxxxxxxxxxxxxxx chances are it would work. The error message you are getting is "Relay access denied". This is normally a good thing since if the mail server is facing the Internet you'd have what is known as an "open relay" which spammers use and would get you blacklisted. I've not worked with postfix or sendmail for quite some time. Most recently I worked with another MTA which had a concept of "Trusted Domains". One could define a domain or a range of IP addresses where relaying would be allowed. I don't know if postfix has that sort of configuration option. The other option, and the best one if you plan to use the server as your SMTP host when traveling or outside the local network, is to configure your system for SMTP AUTH. With SMTP AUTH a user authenticates to the server and then is allow to send mail anywhere. -- In reality, some people should stick to running Windows and others should stay away from computers altogether. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
