* If you specify POP_NO_NOPROT and this library is unable to provide either

* integrity protection or encryption, pop_open() will fail. The pop_open()
|
|
* call will attempt the highest level protection available; i.e., if both
|
|
* server and client support encryption (and you do not provide the
|
|
* POP_NO_ENCRYPT flag), that will be used; if both server and client support
|
|
* integrity protection (and you do not provide the POP_NO_INTEG flag), that
|
|
* will be used. If neither of these are available, and you have not
|
|
* specified the POP_NO_NOPROT flag, then this will be a normal, unprotected
|
|
* connection.
