fix build
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.
Change the syntax to 'limit mta for domain "my.domain" ...' and
and introduce 'limit mta ...' to change the default settings.
Defaults are inherted by newly specified domains.
