I started on a ZX Spectrum and have always thought 48 kB was a whole lot :)

But my reason for wondering about database size is that I am also
thinking about splitten them over users, such as a separate spam filter
for aliases like [email protected] that cover an area of interest
for the mail user.  Or IMAP subfolders.

Bogofilter is likely to be useful to sort email into the right alias
and/or IMAP sub-folder (including ones for Spam and Unsure).  But that
would not allow for the light-weight alias [0] support that we're after
for our IdentityHub project [1].  That got me thinking / playing about
the database size.

I did notice that the number of cases is a #define now set to 2, so a
more practical approach to this alias sorting idea could be to simply
have larger records with counters for each alias.  [But that would make
it a -dev discussion I suppose.]


Thanks,
