Mac 10.14.4 & Apple Mail 12.4 SMTP failure
Mac 10.14.4 with apple mail 12.4 and user can no longer send e-mail with DMARC failure response. Client has Yahoo, Gmail, Centurytel, and iCloud e-mail accounts. No account can send e-mail due to every account was trying to use GMAIL for SMTP. Tried adding a iCloud SMTP server as Apple recommended, but once I select iCloud for SMTP on any account it quickly defaults back to None. I have scanned to computer for viruses with Avast Free, as the computer had no protection and she had fallen victim to a tech support scam on this computer.

I have tried all of the accounts, reset the passwords, verified all of the settings. I have tried auto settings and manual. I will have access to the laptop again on Friday, and will try the SWAKS. I am very used to Gmail settings in Windows programs, but the Apple Mail latest version is very different. We rarely see any Macs in this area. 98% Windows users.
Mail debugging is always an adventure.
Give SWAKS a try + post (text not image) SWAKS output.
Likely SWAKS will show the exact problem + you can fix this instantly.

One other thing to check.
Make sure port 587 is open on the Mac with the problem.
Port 587 is usually open by default + if it's closed mail submission will fail.
If this is the case, SWAKS will show it's unable to even start a transaction with Gmail, in the form of a connection failure.

In Mail.app, go to account preferences (Command , [comma] - select accounts) Select Server Settings and make sure each account has an appropriate outgoing account server set.
You're supposed to be able to choose the outgoing account. If it's always trying to contact the gmail servers, DKIM and SPIF tends to block you from connecting directly and sending spoofed content.

The outgoing server is where it changes back to none.
Post output of running SWAKS, as many times looking at the entire SMTP conversation answers this type of question instantly.

It is on the schedule for Friday still. No access until then.

SWAKS answer was blacklisted. I have checked the client IP (Since all work has to currently be done at their site) and it was listed on a couple. I will next be asking for removal of mac book to another location for further testing.

Also today I can choose the Centurylink SMTP server (They are on Centurylink DSL). All other SMTP options fail.
Sending on Centurylink SMTP is blocked (Blacklisted) IP according to Apple Mail.
