failed to run on android about mailkit HOT 6 CLOSED

This is expected behavior for ANY network app because sometimes servers are down or unreachable for one reason or another.

You can work around this particular error by disabling certificate revocation checks, but I wouldn't recommend it in most cases.

client.CheckCertificateRevocation = false;

This was all explained in the FAQ, by the way, which was linked in the exception message.

How can I make the exception message clearer? I get asked this question at least once per week, sometimes daily.

Do people not read exception messages and just immediately jump to reporting "bugs"? Do they not notice the link to the FAQ?

I spent a lot of time working to make SslHandshakeException helpful instead of just letting Microsoft's SSL exceptions bubble up to users because those exceptions are extremely useless.

SslHandshakeException, on the other hand, gives you all the information you need on a silver platter.

Honestly it seems like no one reads exception messages to me and assumes all exceptions are bugs.

Why?

Thanks for your reply. I really have read the FAQ and even googled on the internent.

1. I thinks this is not the problem of mail server
   because the same code is ok on windows and linux, and they all connect the same mail server

2. I tried STARTTLS before, it just blocked, no error no response.

3. network is ok.

This maybe not a bug, as I googled, no one report such problem on android. Maybe I should set some special param to adapt the mail server. But the same code is ok on other platform. Could the library handle the calling difference on different platform?

I never said it was a problem with the mail server. It's a problem connecting to the ssl certificate authority server.

This is something that System.Security.dll's SslStream does in order to verify that the SSL certificate is authentic.

It has nothing to do with MailKit and it has nothing to do with your mail server.

Thank you for explaining the problem.
So maybe the root problem is System.Security.dll's SslStream is not very stable on android?

I doubt that's the problem. But go ahead and go to the dotnet project'a GitHub page and file a bug report.

ok, thanks
