Hi guys -
I originally assumed only POP3, because of this FAQ from your site:
https://www.totalchoicehosting.com/faq/thunderbird.html
which I got to from this site:
https://support.totalchoicehosting.com/index.php?/Knowledgebase/Article/View/5/1/how-to-set-up-your-e-mail-client
then clicked on Email on the next page.
Thanks, I seem to be using IMAP now. I was surprised I shouldn't be using mail.mydomain.org.
Thanks,
Valerie
