How do I retrieve mail from remote servers/accounts and file that mail into Citadel?

In the past, this was done using the popular fetchmail utility. However, this is no longer necessary, because Citadel now has this functionality built in.

In WebCit, imply navigate to the room into which you wish to fetch messages (usually your “Mail” room, i.e. your inbox) and select Advanced –> Edit or delete this room –> Remote retrieval, and then enter the hostname of your remote POP3 mail server, along with the username and password of your account there.

You will also notice that you can elect to keep messages on the remote server or delete them.

There is also an option to set the “interval” between collections. This setting is in seconds. If left at zero POP3 collection will occur at the system default interval. If set to a non zero value then POP3 collection for this room will occur at the configured interval. Note, however, that the system administrator can configure a low limit for this interval, if you configure an interval lower than the configured limit then this room will collect POP3 mail only at the interval limit set by the system administrator.

FreePOPs can be plugged between citadels pop3 aggregation service, and various web-email providers that don't offer pop-access. Note that you need to disable citadels pop3 (non ssl) service, so it can bind port 110.

Aggregating remote messages via RSS is done via the same method.

RSS feeds are collected at the interval configured as the “Network run frequency” which is configured by the system administrator.

If you wish to use the text mode client to perform the same configuration, use the ”.Enter remote POP3 accounts” command (type ”.e3” at the keyboard).

If however your upstream provider doesn't support POP3, (and fetchmail is a bit more versatile here) This sample config snippet might help you with fetchmail:

poll someimapserver.org protocol imap
username remoteuse-email@somedomain.org is yourcitadelaccount@yourcitadel.org here
password Opensesame
smtphost /var/run/citadel/lmtp.socket
smtphost /usr/local/citadel/lmtp.socket

(the first smtphost is in LHFS Mode, the second in easy install mode)

Some oldfashioned providers just provide one account to poll per domain. Original Recipients are provided in a special header, that needs to be restored while delivering it to citserver. Heres a sample /etc/fetchmailrc:

set daemon 600
set postmaster "postmaster@yourdomain.org"
set no bouncemail
set no spambounce
set logfile /root/fetchlog
poll mailhost.yourisp.com aka yourdomain.org
envelope "X-Envelope-To"
user "username@yourisp.com" with pass "password" to * here fetchall
dropdelivered
smtphost /usr/local/citadel/lmtp.socket
smtphost /var/run/citadel/lmtp.socket
smtpaddress yourdomain.org

note that the token after aka is used to split the email address specified by the X-Envelope-To header.
X-Envelope-To may change depending on your provider.
