  1. IP whitelist from SPF record

    IP whitelists for big providers a kept in DNS SPF records.
    In case of big providers they are really long lists of CIDR, and it would be best if Mailgun could automate their lookup and update.

    Example:

    1. Instead of CIDR, use SPF: google.com. To do that we need to perform multiple DNS lookups, since any SPF record may contain "include: $DNS_DOMAIN".
    $ host -t TXT _spf.google.com
    _spf.google.com descriptive text "v=spf1 include:_netblocks.google.com include:_netblocks2.google.com include:_netblocks3.google.com ~all"
    
    $ host -t TXT _netblocks2.google.com
    _netblocks2.google.com descriptive text "v=spf1 ip6:2001:4860:4000::/36 ip6:2404:6800:4000::/36 ip6:2607:f8b0:4000::/36 ip6:2800:3f0:4000::/36 ip6:2a00:1450:4000::/36 ip6:2c0f:fb50:4000::/36 ~all"
    
    

    The same for all other _netblocksX.google.com

  2. IPv6 support

    We are running out of IPv4 addresses, and while the world is (slowly) working on supporting IPv6 (which is also an internet standard since 2017) Mailgun remains behind.

  3. Track open events also if images are blocking

    Part of my recipients are blocking images by purpose, it's a principle.
    They won't change it.
    As a result, the open event is not fired for those recipients.
    I expect Mailgun to enable me track ALL OPEN EVENTS, regardless to the recipients settings.
    Thanks!!!
