6.2.6. POP3
POP3 is a mail transfer protocol that differs from SMTP in that the transfer of mail is directly from a
server to a user's client software.
POP3 ALG Options
Key features of the POP3 ALG are:
Block Clear Text Authentication
Block connections between client and server that send the
username/password combination as clear text which can be
easily read (some servers may not support other methods than
this).
