POP proxy

Example: proxy POP-DeleGate

firewall# delegated -P110 SERVER=pop


external% telnet firewall pop
+OK Proxy-POP server (DeleGate6.1.0) at firewall starting.
USER username@servername
...
Instead of "@", "%" or "#" can be used as the delimiter between username and servername, like username%servername or username#servername.

Example: POP MOUNT


"pop://user@server" is represented as "pop://server/user" internally thus it can be controlled by MOUNT as follows:

MOUNT="//* =" ... don't rewrite if a server is specified by the user
MOUNT="* pop://defaultHost/*" ... specify default POP server
MOUNT="user1 pop://host1/*" ... let the "host1" be the server of "user1"
MOUNT="//pop2/* pop://host2/*" ... map user@pop2 to user@host2, hiding real hostname "host2"
MOUNT="//*%S/%S pop://server/*%(1)@%(0)" ... forward user@host as is to pop://server/user@host


When a target POP server indicates that it accepts APOP authentication (by a greeting message with a time stamp), DeleGate tries login with APOP first, then retries with USER+PASS when APOP failed. But if a server never accepts APOP in spite of its greeting, the useless trial with APOP can be suppressed by "noapop" MountOption like this:

MOUNT="* pop://server/* noapop"

Example: NNTP server to POP client gateway

SERVER=pop
MOUNT="* nntp://nntpserver/*"
MOUNT="ns2-* nntp://nntpserver1/* apop=password"
MOUNT="ns3-* nntp://nntpserver2/* pass=password"


Clients are expected to send a newsgroup name as a user name.

Example: POP server to HTTP client gateway

firewall# delegated -P80 MOUNT="/mail/* pop://mailHost/*"

This DeleGate provides mailboxes in POP server (at mailHost by default) to HTTP clients. Clients accessing to "http://firewall/mail/" are required to enter Username and Password for POP server at mailHost as authorization information on HTTP. If Username is in the form "user@mailHost2", not mailHost but mailHost2 is accessed as a target POP server. Each mailbox of User at Host server is named as "http://firewall/mail/+pop.User.Host", thus you can directly specify User and Host in URL.
