Can the Mail Server in aaPanel accept external connections such as from Joomla.
I have two VPS server, one as a mail server and the other as a webserver. My site on the webserver cannot connect to the mail server to send emails.
Ive searched for days for the answer to solve this issue and end up going down rabbit hole after rabbit hole with no answer. None that I understand at least.
Any ideas how to fix this error: Presumikng the mail server can have external website connections.
SMTP Error: Could not connect to SMTP host. Connection failed. stream_socket_enable_crypto(): SSL operation failed with code 1. OpenSSL Error messages: error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure
By the way, Im using STARTTLS as I usually do with Joomla. All the usual SMTP settings, Authentication yes, port 587.
Any ideas appreciated. Thanks
