I have the following environment: Europe, Austria, A1 Provider, sending with Thunderbird 78.7.1(64-bit) on GNU/Linux Ubuntu 20.04 LTS the outgoing configuration is SMTP port 587 with STARTTLS
everything works fine, but sometimes the Provider SMTP Server is BUSY. I get in thunderbird client a pop up "load too high (#4.3.0)" and then the email is in 'sent' folder. as I always put myself a CC in every email, I can guarantee that the email was not processed by the SMTP server. this matches the pop up message. this is a transient SMTP server error. thunderbird client knows this and shall not put this failed output into folder 'sent' , but into folder 'draft' for later retry. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1215882 Title: Emails are silently discarded on 554 reply to STARTTLS To manage notifications about this bug go to: https://bugs.launchpad.net/thunderbird/+bug/1215882/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
