A fast and robust implementation of the RFC1939 POP3 protocol.
|
|
It supports both BSD-type and SysV-type mailbox formats. Cucipop
|
|
assumes that the mailbox it serves is not simultaneously accessed
|
|
by a mailreader. Concurrency and locking issues are handled
|
|
graciously if they restrict themselves to the mail delivery agent.
|
|
|
|
Feature summary for cucipop:
|
|
+ It's fast (optimised for frequently polling POP3 clients)
|
|
+ It's less filling (i.e. small)
|
|
+ Does not use *any* temporary files (which also means that the
|
|
startup time is spectacularly short, and there can never be
|
|
any stale temporary files or doubled mailboxes)
|
|
+ It can therefore serve *any* size mailbox without requiring
|
|
additional storage beyond what the file already occupies
|
|
+ A fully compliant, all frills attached, RFC1939 implementation of
|
|
the POP3 protocol
|
|
+ This means that it supports APOP *and* UIDL
|
|
+ It includes the option to sabotage the UIDL command (to defeat
|
|
undesirable "Leave mail on server" clients)
|
|
+ It also supports an optional autodelete mechanism, so that any
|
|
RETReived message is automatically deleted
|
|
+ Autoadaptive, simply start it and it will know if it has been
|
|
started from inetd or as a standalone daemon
|
|
+ Security conscious, i.e. the APOP support, already has hooks
|
|
for shadowpasswords, and defeats password guessers by an adaptive
|
|
verification delay
|
|
+ Supports both BSD and SysV (Content-Length) mailbox formats
|
|
+ Native support for /var/spool/mail/b/a/bar type mailspools
|
|
+ Is the only popd to perform reliable mailbox locking across
|
|
NFS as well (it uses the same excellent and proven locking
|
|
algorithms as does procmail)
|
|
+ Provides flexible logging of statistics and auditing events
|
|
+ Does not impose *any* limits on line lengths, mail length,
|
|
or the use of any character (any 8-bit character, including '\0' is
|
|
allowed) in the mail
|
|
+ Secure system mailbox handling
|
|
+ Has hooks to ease moving the mailboxes to any location you'd like
|
|
+ Has hooks for other authentication schemes (e.g. Radius)
|
|
+ Has hooks to virtualise the popserver
|
|
+ It runs on any POSIX and ANSI C compliant system
|
|
+ Is clock skew immune (e.g. in the case of NFS mounted mailboxes)
