Hi,
This is an idea, but I don't know how to implement this.

Hello,
I will explain what I need to know.
I have 3 Servers:
One of them is just a Domains Server.
The other two are Mailboxes Servers. They have the email
accounts for all the Domains from the first Server.
All these mailboxes' POP and SMTP are accessed through the Server address:
mail.domainnamea.com. mail.domainnameb.com. mail.domainnamec.com.
and so on.
If someone who accesses my Roundcube, fill the Server field with any other POP Server name elsewhere, he will read those emails. How to avoid it, so that only mailboxes in one of my two Mailboxes mentioned above can be accessed?
Perhaps an outbound iptables firewall rule, so prevent the roundcube server from accessing any POP3 / IMAP server other than your servers?
Thanks a lot.
