sendemail trough exchange server smtp ssl / starttls problem #19

rezatbaher commented 5 years ago

when i try to send 50 emails using sendemail i get this log in a random number . command im using is this : sendemail -l email.log \ -f "myemail@mailserver.com" \ -u "Automatic email" \ -t "myemail@mailserver.com" \ -s "smtp.mailserver.com:587" \ -o tls=yes \ -xu "username" \ -xp "password" \ -o message-file="tempemailbody.txt"

with gmail and postfix there is no such problem . this is not because of network , i did netcat to exchange server and even telnet to verify before sending each email but happened again . ERROR => TLS setup failed: SSL connect attempt failed error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed

sending email using ssmtp has no problem with exchange server

There are several versions of TLS and earlier ones have security flaws which means that they are deprecated. I would check to see what TLS is required / used in each of these environments.
