Re: Email with dynamic IP blocks
Internal networks bypass most of the tests, however, when user use their phones with either 3G/LTE/WiFi/etc, the connection is seen as an external network (certainly since it is not a 192.168.) and because of that it triggers all tests.

But you said they authenticate...
I'm not an e-mail expert, but I can see no reason why an authenticated user to the mail server is getting run through all those spam tests on the outbound direction. I would strongly consider changing your configuration if at all possible.
Do your users get spam-tested between internal mailboxes too?

You should be able to bypass certain tests (or all) for authenticated users.
For example when my users are authenticated on postfix I don't send them to regular spam filtering queue, but to alternative filtering queue that is less strict on many items.
