Thank you Matus,

The above set of 5 lines needs to be added in amavisd.conf anywhere as 
such, or it must be included in some particular block or otherwise?

I understand that you have not included the actual (3 or 4 digit) 
password in the rules. Shouldn't it be added somehow, to reduce risk of 
false positives?

Please clarify!

I would like to try that!

Thank you very much for your guidance!
