At least a portion of a transmission of an outgoing first email from a first email account to at least a second email account is encrypted. Second email address data is changed corresponding to the second email account to cause replies to the first email intended for the second email account to be sent to an intermediate device prior to being routed to the second email account. Replies to the first email are then sent to the intermediate device and sent over one or more encrypted channels. Replies to the first email including the changed email address data are decoded to identify the second email address data associated with the second email account. A reply to the first email is then sent to the second email account based on the identified second email address data.

A trunk connection to a stack of network switches is coupled to physical ports distributed among the switches. A switch has an internal logical port for a protocol engine. A packet received by way of the trunk at a port on a switch which does not host the protocol engine is sent over a cascade connection to the host switch with a tag that is interpreted within the host switch as if the packet cam from the logical port. The tagging and interpretation distinguishes between packets which might or might not be intended for the protocol engine and did not arrive by way of the trunk from packets which are intended for the protocol engine and have been received by way of the trunk.
