You should read this:

Particularly the section around this command:
ALTER TABLE tbl_name MAX_ROWS=1000000000 AVG_ROW_LENGTH=nnn;

This blog is also full of good info:

You can safely clear <deleted> entries as long as your mail server doesn't have the
copies in your mailbox. If it does Eventum will download them again.

Eventum should always just display seb_body and just use seb_full_email to calculate 
attachments. However, in the past I remember some sort of bug that required it.

I would just increase the size of the table for now.
