Looking for webmail application to exist with already existing mailserver (POP3/IMAP/SMTP) hosting approx 1000 separate mail domains. Must run on either PHP or ASP* (*preferred) with MySQL backend on Windows IIS 6. Have already tried RoundCube and various other apps but none of them reliable enough.
Must be able to support upto 5000 concurrent connections.
Standard tools like personal address, file attachments, message filtering etc all a must. Not fussed if pre-written application, does not have to be bespoke but will need to be rebadged. If incorporates calendaring and agenda then all the better.
Will need to fully trial and test before payment made.
Application license will need to cover multiple installs across server array - this is not a single installation.

We can work out the deadlines when we get detailed requirements. I have been working on ASP and .NET since last two years and have done several projects on the same. Thank You
