Hello, I need your help guys.
All the replies that I got from providers are not acceptable for me.
Here's the thing.
Cpanel account, small company of 10 guys with a mail account for each one.
Each user only knows his mail's password.
So, as the hosting is configured, someone could send mails from another real mail account. How?
Quick and simple example: John only knows his user/pass and he did set the profile in Outlook.
Steve is mad with John and just created a profile in the mail client with john's mail, knowing only [email protected]. He left the password input in blank and he could be able to send a mail in John's names.
AFAIK, setup SPF is not helping here, cause it's not a matter of IPs. For some reason, the mail's account doesn't ask for SMTP authentication.
I hear about Exim as the unique option in Cpanel and postfix like a possible solution with other control panel.
The goal here is that each mail account which is set in any mail client without the right password, should be prompted to fill the mail's password.
Any idea how to do this?
Thanks in advance for your help/time.
Edward
