Sergii,

Bogofilter has no particular need for space.  The need depends on mail
volume and BerkeleyDB's storage efficiencies.  Postfix's default of
5120000 worked fine for me for the best part of a year.  In my example I
used 73000000 purely as a value larger than postfix's default 5120000
value.  Over time, the wordlist size will grow and likely will exceed
whatever size you set today.  You should use a size that's suitable for
your needs and is consistent with any disk quotas that may affect you.

Both will work.  Having the info in the docs provides a local source of
info while info on the mailing list using a web search to find it.
