Simply reducing the notifications will certainly help. 2.7 is in Beta and it's looking good. So unless something show stopping is found I would anticipate 'weeks'. Hard to be more accurate than that. Steve

@dragoangel Maybe https://forum.netgate.com/category/30/bounties If you really need it and are willing to pay for it. Else the best you can do is hope that it will come some time...

I'm also wondering about this behavior. I've three DynDNS host names which are to be updated on WAN IP change and I get two notification mails on every IP change. Is it possible to prevent the double notification or is there an explanation for that?
