George Noory?  But I preferred Art Bell

Hey, that large company I worked for, well, one of the employees who 
also got a lot of email, was injured and was out for like 3 months.  Her 
inbox got too full with unread mail and brought down the entire email 
system.

I know one guy that would purposely jam another’s outgoing email.
Once he detected who it was from he would just turn on transmit.  
This was on a CSMA/CD coaxial network.

Internet email isn't anonymous,  never was.  Even in the early 
days.   There has always been a multitude of ways to track email back 
to the origin server.  And there has been a multitude of ways to 
obfuscate but not hide that origin.
Any anonymity you may have is based on the origin server either not 
knowing or not being willing to disclose that information. Every 
email received generally will be able to be tracked back to the 
origin server,  with the caveat that sometimes the owner of the 
origin server will be unable to be determined since any random person 
can spin up a server, send mail,  and drop off the planet.
Note that spf and dmarc don't validate the user.   They only validate 
that the email originated from servers known to send mail for a given 
domain and provide some cryptographic assurance of that fact. It's a 
way for legitimate companies to ensure that email that appears to 
come from them actually comes from them and for companies like google 
to be able to reject what appear to be emails with spoofed sender 
information.

    is most of the free email servers won't allow users to send
    more than 10 emails at a time and you have to wait up to an
    hour before you can send 10 more.  That's why I tried to build

Technically, AGM batteries are lead acid batteries. But not all lead acid
batteries are AGM, obviously.

Not 100% the same but the charger will probably work.  I think the
chemistry is different enough it justifies an AGM charger (you'll see
chargers with a button/dip switch for sla/agm/etc).
