Hello -

 I have SmarterMail behind a reverse proxy and generally speaking, it behaves just fine in terms of detecting the relative URL prefix that I use, i.e. www.domain1.com/email, www.domain2.com/email etc. Note that I don't have a URL set server wide because I use the same instance for multiple domains, each with their own URL.

In build 8538, I noticed that certain URLs don't detect/honor the prefix, specifically those resources under /interface/app/email/ - the /email is not prepended to the URL.

Thanks,

 Elazar
