Though I live in SW Missouri, I've followed this list for years.
My current provider is terminating email service soon.
I run SeaMonkey on Debian.
Wishing to avoid ads, I specified "paid" in the subject line.
I've found services that seem generally suitable, *BUT*
-- one requires existence of a mobile phone account
I don't have a smartphone due to vision problems
-- another { catering to small businesses} needs a custom domain
I don't under the ramifications of creating a domain
In one sense, privacy/security is not a major issue as >90% of my usage
is "public" mailing lists such as this or tech oriented Usenet groups.
Suggestions/guidance please.
TIA
