Smtp Email Settings Problem!

Hi!

I'm haveing a problem with SMTP settings.

Im useing this settings :

Method of sending emails : via SMTP server

SMTP host : dev1se.nazwa.pl

SMTP username : powiadomienia@2xgym.pl

password: emial-password

use encrypted connection : SSL

path of sendmail program is at it waas : /usr/sbin/sendmail

and i geet this error:

ErrorMessage could not be sent.
Mailer Error: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

if i hange SSL to None i get:

ErrorMessage could not be sent.
Mailer Error: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting
×ErrorMessage could not be sent.
Mailer Error: SMTP Error: The following recipients failed: arianw@o2.pl: : Sender address rejected: not owned by user powiadomienia@2xgym.pl@gmail.com>
×ErrorMessage could not be sent.
Mailer Error: SMTP Error: The following recipients failed: sfd@example.com: : Sender address rejected: not owned by user powiadomienia@2xgym.pl@gmail.com>
×ErrorMessage could not be sent.
Mailer Error: SMTP Error: The following recipients failed: adwozniak@gmail.com: : Sender address rejected: not owned by user powiadomienia@2xgym.pl@gmail.com>

So i contacted my hosting company ad they recomended adding outgoing port numer after the host name .

so i changed

dev1se.nazwa.pl:465

and it freezes ,after refreshing button for open to proceed is changed but no email sent.

if i use dev1se.nazwa.pl:465 and change encription from none to SSL i get this:

ErrorMessage could not be sent.
Mailer Error: SMTP Error: The following recipients failed: arianw@o2.pl: : Sender address rejected: not owned by user powiadomienia@2xgym.pl@gmail.com>
