Pl. beware of indexing.
It is a double-edged sword.
Indexing too many columns would increase the data-size.
One can first run a query with explain extended clause (in MySQL

That can tell which column(s) would need an index.

That's a fair statement.
Indices not only increase the size of the data, they also slow down db
writes, because the index tables need to be written as well as the
data tables.
Still, you want to avoid a full table scan on a table with millions of

The SMTP protocol can be encrypted at a low level with either TLS or
