Re: [AFMUG] mail servers

 A host is a host from coast to coast.  And nobody talks to a host 
that's close, unless the host that isn't close is busy, hung, or dead...


UUCP email days...

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.

Hmmm, Windows or Linux? 
Sounds like a client is slamming the server locally. 
Have seen this with fairly large mailboxes and IMAP
