introduce expand string modifiers, diff by Colin Didier
Introduce a mta_limits structure to replace the hardcoded limits on the mta.
Various limits and delays are configurable on a per domain basis in smtpd.conf
using the following syntaxe:

limit for domain "my.domain" <keyword> <value> ...

The values are found in limit.c. They will be documented shortly.
They are still subject to changes.
