A thermosetting resin composition has good storage properties at room temperature and an unreacted epoxy resin etc. Groups of TCAM entries are programmed such that each of its entries differ by more than a predetermined calculated count of ones distance of k bits, where k>0. The mechanism also makes note of the line number table offset. Emails with signatures that are successfully verified can be identified as having a higher priority level than emails without the cryptographic signatures. Preferably an adjustment is selected that causes the monitored temperature to approach the set temperature.
