True. However, I'm not completely sure how the existing mail servers do it. I 
suppose they create index files for all the different fields in order to 
speed everything up.

Whether these indexes are stored in small index-files on the filesystem or in 
an SQL database doesn't make much of a difference, so your proposal sounds 
okay to me.
