+POP:
+ In the third case, the gateway reads all messages from the POP server
+ specified and submits each in turn to the roundup.mailgw module. The
+ server is specified as:
+    pop username:password@server
+ The username and password may be omitted:
+    pop username@server
+    pop server
+ are both valid. The username and/or password will be prompted for if
+ not supplied on the command-line.
