Grammar

1. Since two different protocols, and possibly two different servers, are used to send and receive mail, it is possible that mail clients can perform one task and not the other. (Is the subject for 'are' 'protocols' only? It is because we have commas in there?)

Thanks.

'In compound like constructions with with, together with, and the like, and those
