I use the Chebucto Community Net for most emails not related to public
lists, where I use gmail.  My mother also used a small local email
provider.  That provider was purchased by a larger company, and my chebucto
emails were being put in a spam folder that she could not see with her mail
user agent, only by using a web interface.  I investigated the spam filter
and found it was from a company that had been purchased by Google.

created accounts used for spam.  These are usually temporary.
