# ipopd(8c)

Post Office Protocol server

## NAME

IPOPd - Post Office Protocol server

## SYNOPSIS

**/usr/sbin/ipop2d**

**/usr/sbin/ipop3d**

## DESCRIPTION

*IPOP2d* and *IPOP3d* are servers which support the **POP2** and **POP3** remote mail access protocols respectively. *IPOP2d* and *IPOP3d* can also be used by **POP2** and **POP3** clients to access mailboxes on **IMAP** servers by specifying a login user name in the form \<host\>:\<user\> e.g., **SERVER.WASHINGTON.EDU:SMITH.**

These daemons have been compiled with MD5 and APOP support.  See    */usr/share/doc/libc-client2001/md5.txt* for additional information.

*POPd* is invoked by the internet server (see [*inetd*(8)](/inetd/8.md)), normally for requests to connect to the **POP** port as indicated by the */etc/services* file (see [*services*(5)](/services/5.md)).

## SEE ALSO

imapd(8C)

## BUGS

The **POP2** and **POP3** protocols are intrinsically less flexible than **IMAP** and do not maintain \`read' vs \`unread' state on the server.  As a result, most **POP** based software transfers all the mail from the server to the client and deletes it from the server.  This necessarily locks the user into using only a single client.

**POP3** does not allow you to specify an alternate folder from the user's default.
