Sending email from Thunderbird very slow
Hello,
When sending email from Thunderbird, it consistently takes 30 seconds to connect to the SMTP server. This is extremely annoying. Log excerpt: Code:
2019-02-06 17:25:10.693000 UTC - 1376[3a10140]: SMTP Connecting to: mail.messagingengine.com 2019-02-06 17:25:40.795000 UTC - 1376[3a10140]: SMTP entering state: 0 Any ideas? Edit: telnet mail.messagingengine.com 465 connects instantaneously Last edited by ao1 : 7 Feb 2019 at 01:53 AM. |

It appears that you are using the old SMTP server and have not switched to using the current smtp.fastmail.com server on port 465 with an app-specific password. See:
https://www.fastmail.com/help/techni...sandports.html With the current recommended settings I get connections in under 1/2 second. Here are logs showing the start of two message send sessions using Thunderbird 60.5.0: Code:

This could be symptomatic of your IP address having a reverse DNS problem, discussed towards the end of this thread: http://www.emaildiscussions.com/showthread.php?t=72258

I got a reply from FM's tech support. It's a reverse DNS issue, I'll have to take it up with my ISP.
