smtp server problems with Mail
I've been unable to send emails from my iMac in Apple Mail for 2 weeks, but I've no problems receiving.
Initially, i stopped receiving images from my network video recorder (nvr) sent via my providers mail server, but then nothing was being sent. I've tried every configuration, and those suggested by my provider, but nothing works. My SMTP server still shows as offline in the SMTP server list. I also cannot send mail via Windows 8.1 bootcamp partition, but everything works correctly from my iPhone.
I have backed up my emails, deleted my mail folder in Users/Library, then rebooted and restarted Mail. At this point, all the same Mail accounts return with all the same problems. Is there another folder I should be deleting? I have also re-installed the Catalina supplemental update 10.15.6 via the Apple web site, all to no avail.
Does this sound like an Apple Mail problem or a mail server problem? It all started after my provider migrated to a different Mail Server. I'm at my wits end with my Mail and my Mail host
