dmta2005 commented 3 years ago

We have been using Serilog email for our .Net Core 2.2 web application projects. It has been working for months. But suddenly the email stopped working. I don't know if anything changed to our environment. It does not send emails any more. It still logging the error into the log file. I have not be able to get it working again. SMTP email still working in our environment. Any suggestions to check for our environment.
Thanks

We found out the reason the email stopped working because TLS 1.2 was enabled. Anyone having the same issues with TLS?

We have the same problem since TLS 1.2 was enabled in the server.

Was you able to resolve the issue? We have problems with both .Net Core 2.2 & 3.1. We just use SmtpClient to send email for now.

Could you please advise, is there any updates? Actually I have the same issue.

Closing as stale, 3.0.0-dev-* consistently uses MailKit on all TFMs so may be the thing to try. HTH!
