I've got 5 email domains with multiple email addresses on each domain. Traditional webmail clients only seem to allow you to browse a single account at a time (ie, you log into that account). With over 20 email addresses I need to monitor, this is obviously a major time sink.
Is there a (preferably OSS, unix-based) webmail client that simulates a desktop email client, ie I log in once and can access all the email addresses from a central control panel? I've considered using a ticket system but that is overkill and not really used to my needs.
AfterLogic WebMail Pro has this functionality (there will be a dropdown where you can select an account from your account list).
Available for ASP.NET and PHP. http://www.afterlogic.com/webmail-client
