…urable via chatmail.ini parameters this by default limits new address creation if load average/disk usage/RAM-usage is too high
…it in chatmail.ini current max connection limits for dovecot (50K) and postfix (10K) are geared for nine.testrun.org. A small VPS would typically have a lot less resources as many operators run on a <10EUR per month budget.

Mainly, this PR rejects new address creation when system is under load, has not much RAM or disk storage left.
It also makes postfix/dovecot max connection limit available in chatmail.ini and lowers the defaults which were geared for nine.testrun.org operations.
