don't get me wrong but that's the same weak excuse as "i do not spam my customers do" so why blacklist me in fact a sane PTR is a prerequisite for relieable mailservices and if you are at planning a public MTA normally you make sure the matching PTR and other things before send the first message if you are at checking the prerequisites and realize you can't get a PTR as needed you can't setup the mailserver on that ISP or need to rent a relay-server - that's part of organize things and at the end competence of a sysadmin
