Hello Slava,
sorry for the delay.
Settings are the same we use for another domain, which works well.
Here are the details of the settings:
From: a valid mail-address
Force from E-Mail: not checked
Mailer: other SMTP
Return Path: not checked
SMTP Host: (internal IP-Address of the Server (10.x.x.x)
Encryption: none
SMTP Port: 25
Auto TLS: off
Authentification: off
Sending a testmail from the WP backend was successful.
But a mail by filling in the web form (contact form 7) is only sent,
when the user has loggend in into the WP backend and keeps a valid session.
Otherwise the circle (clock) rotates endless without sending a mail.
Thanks & regards
Martin
