(or bugs) in Dovecot, that won't happen anyway. So you could just as
well set it to something like 1 gigabyte, and you'd never notice
I don't know how to properly measure how much OpenSSL takes memory.
It probably depends on a lot of things. If the memory size setting is
too low, the login process will be killed. So as long as you don't
see any "login process killed" messages in log files, the value is
