SKSMTPMessage错误-无法完成该操作。（OSStatus错误-9807。）

Question

Can anyone please help me to understand the error- “ The operation couldn't be completed.(OSStatus error -9807.) ”.

I googled & found, except SkSMTPMessage , sometimes this error comes in AVAudioPlayer class but the number is different ie 9800 .

My questions are, A) would you please tell, what is significant of number here, B) why such error occurs in code?

I found one solution here-

It seems there are some compatability issues with iOS 5+ or later and this smtp app because iOS started using TLS 1.2.

find the source in the SKPSMTPMessage.m , and modify the source like following, it works

//CFDictionarySetValue(sslOptions, kCFStreamSSLLevel, kCFStreamSocketSecurityLevelTLSv1); 
CFDictionarySetValue(sslOptions, kCFStreamSSLLevel, kCFStreamSocketSecurityLevelSSLv3);

It didn't work in my case.

In the case, when i tried to send email with my gmail account it worked , but when I tried to send it from my companies SMTP credentials, it didn't work.

How can I solve such issue from my app?

Answer 1

It might be caused by SSL certificate. I have encountered the same issue and it turned out that my server is using self-signed SSL certificate and iOS has trouble with it.

Answer 2

Add this line:

// Only do this for self-signed certs!
emailMessage.validateSSLChain = NO;
