## Mail Server
Todo: Resolve the issue with the Three / 3 about the IP PTR Record mismatch where the mail.prg-radio.org off the IP
record is XXX.XXX.XXX.XXX.mobile.3.dk and not XXX.XXX.XXX.XXX, which hecks up the secure reverse DNS lookup.
Current solution uses SMPT2Go, which has limited outbound mail limits.
