Thank you, I proceeded to forward the ip unlock request.
Is it possible that although each domain and hosting has its own ip, it is used for sending emails and consequently the general ip of the server where plesk is installed is compromised?
Below are the logs /var/log/maillog .
I've tried sending a mail to an address that never receives mail from the server.
I state that the sending takes place through the roundcube webmail.
Hello everyone,
I have a problem with mail and qmail.
Some mails are sent correctly through webmail while most remain in the mail queue and do not reach the recipient.
What can I fix?
