Smtp errors for Outbound mail

Support
1

I use Porkbun as a mail host. My Inbound imap settings are fine and I can receive emails just fine.

However, my outbound smtp traffic stopped working sometime after 8/11.

Porkbun support found a very old post about postfix issues with K-9 but I definitely was able to send something out OK on 8/11.

Any suggestions for fixing? I’ve tried the other option (ssl/tls, port 465) besides starttls and port 587 to no avail.

What release of K9 are you using? When did you install it, i.e., did you update your installed K-9 after 8/11?

What error and/or symptoms are you getting when you try to send mail?

Has your provider acknowledged making any system/configuration changes since 8/11?
