2. The method of claim 1 , if there is no meaningless lexical unit with a predetermined numerical control sum matching the numerical control sum of the first potential meaningless lexical unit in the lexical unit database, the method further comprises: (i) subdividing the first potential meaningless lexical unit into at least two smaller lexical units and determining at least one smaller lexical unit as the second potential meaningless lexical unit; (ii) determining, by the server, a numerical control sum of the second potential meaningless lexical unit; (iii) matching using a second parameter the first potential meaningless lexical unit with lexical units from the lexical units database, wherein matching using the second parameter comprises matching the numerical control sum of the second potential meaningless lexical unit with predetermined numerical control sums of meaningless lexical units from the lexical units database; (iv) determining, by the server, the second potential meaningless lexical unit is a meaningless lexical unit if the lexical units database includes at least one meaningless lexical unit with a predetermined numerical control sum matching the numerical control sum of the second potential meaningless lexical unit; (v) if the second potential meaningless lexical unit is determined to be the meaningless lexical unit, generating, by the server, the abstract of the electronic message, the abstract not including the at least one meaningless lexical unit.

The method of claim 2 , wherein the first potential meaningless lexical unit is a paragraph and the second potential meaningless lexical unit is a sentence from the paragraph.
