Squirrelmail login settings
I'm running postfix as a mta and dovecot as a ms and I also set up squirrelmail. Everything works great, users can logon and send and recive mail. I even found a plugin for so that it detects the domain in the browser heder and sets the sending email to that address(webmial.something.com -> firstname.lastname@example.org and webmial.somethingelse.com -> email@example.com user is the same one). But the solution is also the problem. Curently all users can logon to any domain that is hosted and send email via that domani even if they can't recive mail on that domain. I would like to limit users so that they can logon and send emails form only specific domains and not all of them.
Is ther any way of doing that or is ther any way of seting up squirrelmail so that users have tu logon like user@domain & pass and not like now just user & pass? And also limiting the logon to some domains.
Thanks for all your help
