I would absolutely settle for a forwarding service, but that's all I use my Fastmail address for anyway.
I would encourage everyone to contact
support@fastmail.com and let them know their thoughts on this matter. (Ironically I had to login to the Fastmail front end in order to send a mail from my Fastmail account, the first time I've done so in yonks). They did reply to me but seem to be holding their line about terms and conditions. They seem to have conveniently forgotten about this page on the original site
https://web.archive.org/web/20021016...ricingtbl.html where it says "US$14.95 one-time fee, gives you a lifetime member-level account."
This situation is outrageous and we have to put pressure on them.
