If you are asking for a recommendation on OS of choice, this is a highly individual matter, often religious. Use whatever you are comfortable with, and is being actively maintained.

No it doesn't. Also I never heard of a case where a master amavisd process would vanish. For a quick overview on a general amavisd-new system health I recommend running amavisd-nanny utility for a few seconds or minutes every now an then, e.g. once a day or when there is suspicion that things are busier or slower then expected.
