Server was not responding to administrative commands and we need to reboot the server.
Server is running fine now for last couple of min and Control Panel is responding fine now.
Actually we had firewall exception added and that need to be reload for new ip. We have also added rule for smtp.gmx.net to port 465.
As per ticket conversation now both are working for you.
Please update us if you see any issue further.
Mail Server is responding slow. We see huge mails in mail queue. It seems spammer has injected huge mails in queue.
We have stopped mail service on server. Cleaning queue and looking into it further.
Due to some user account compromised spammer has injected huge mails in mail queue. We are cleaning up queue. Mail Service is being stopped for cleaning mail queue.
Dear Cosinus,
As per communication in ticket, phpmailer is working for you. It is always good to use SMTP auth instead of mail() :)
Please feel free to ask if you face any issue further.
Re: Mail3 - mail3.g********.com IMAP Service
IMAP service creating too much load on server. We have stopped it again and it might take a bit time to resolve the root cause of this.
