Mail is not sending from SMTP

SSL operation failed with code 1. OpenSSL Error messages: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

Seems mail server ssl is not there please check mail domain ssl and try then

I tried still facing same issue.

Connection could not be established with host mail.gudibali.com :stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

is this the name of your mail hostname ?
( i guess it’s not… if not… try use your mail hostname )

how if you sent from rainloop and/or snappy ?

I am sending the mail from SMTP configured from my application…
config

already try send from webmail ?
and:

I guessing this settings for laravel. If yes please refer here > php - What's the correct configuration to send emails using Sendmail in Laravel? - Stack Overflow

Port 587 should be tls.
MAIL_ENCRYPTION=tls
