we ran into this error recently, and we don't know what is the issue, if our mailserver is having this error or the receiver mailserver having a problem:


Recipient: <ada<_at_>yyyyy.com>, Result: delayed, Status: 4.4.1 421 Cannot establish TLS with SMTP server x.x.x.x:25, SSL_connect error 1:error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

Our SSL certificate is working properly, i have checked that with COMODO SSL Analyzer.

Any info to correct this issue is appreciated, thank you.

This issue is resolved. I disabled our external Avast Antivirus server to check email.
