Hmm, With exim you can have any number of domains or users, the only limitations will be your har disk space and OS which can be circumvented if you use mysql or some other sql database for authenticating and storing user information. You can easily integrate virus scanning into exim because it has a filter function and it is matter of inserting your favorite antivirus there.
Forget about integrated webmail, exim is an MTA not some bloated microsoft product, you can achieve this with any number of webmail products out there like sqwebmail, squirrelmail, IMP etc... The same applies to WAP support which you can get by installing and configuring kannel http://www.kannel.org Browser based admin tools are a simple matter of adding some php scripts. It has TLS/SSL support ofcourse but do not expect exim to do http or pop3 or IMAP. It is an MTA not an OS. However A friend called Brian Candler has bundled all this functionality.. i.e. web based admin, webmail, exim, courier-imap, courier-pop3, LDAP into one simgle package that installs beautifully on linux or FreeBSD. Take a look at http://www.linnet.org It should do all that you're looking for if you want a one stop shop for all your needs. Noah.
