If not THE problem it certainly will be A problem. Running Debian
testing on an email server is asking for trouble, use stable for that.
If you really need bleeding edge try
www.backports.org or use unstable.
Breakage in unstable is fixed much sooner whilst it may take weeks to
propagate through to testing.
