I've been using Exim for years and wouldn't use anything else for a large-scale mail deployment.
If you've already got your accounts in LDAP (as implied) then you just need Exim, SpamAssassin and ClamAV. Exim includes the Exiscan-acl patch from version 4.5 so there's no need to mess about patching the source.
If you need any help with setting this up then this is a service Bashton Ltd can provide (link in sig).
