I saw this post where someone was having this problem, but it seems to have been closed because it’s old.
Hello, I can send and receive all emails except that I can’t receive emails from gmails. I’m getting the following error about email delivery failure from sent email to server.
The response was:
TLS Negotiation failed: FAILED_PRECONDITION: starttls error (71): 94771312888008:error:10000417:SSL routines:OPENSSL_internal:SSLV3_ALERT_ILLEGAL_PARAMETER:third_party/openssl/boringssl/src/ssl/tls_record.cc:594:SSL alert number 47
Please let me know the fix, I’m dying because of it :\
Solution:
This way i solved the problem and can now receive mails from gmail.
On cloudflare please disable proxy for the following DNS record.
- Webmail
- Your hostname subdomain, if mail.yourdomain.com is not your server host name
Try sending it this time, it will work.
