To set up an IMAP mail server install task-imap
which
installs wu-imap. IMAP will then be running.
A sample IMAP session:
$ telnet imaphost 143
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
* OK Microsoft Exchange IMAP4rev1 server version 5.5.2655.37
(imaphost.act.cmis.CSIRO.AU) ready
|
To test a connection:
$ telnet localhost 143
Trying 127.0.0.1...
Connected to athens.
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 UIDPLUS CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT QUOTA IDLE ACL ACL2=UNION] Courier-IMAP ready. Copyright 1998-2004 Double Precision, Inc. See COPYING for distribution information.

To create a virtual user account to access a mail account through a
different user with a different password (so that you might reduce the
risk of disclosing your normal login password) you can create a
virtual user and store the password in a userdb database that
courier-imap will use for authentication.
First, create the ``pretend'' user:
# userdb kayonmail set home=/home/kayon mail=/home/kayon/Maildir \
uid=kayon gid=kayon
|
Create a password for this user:
# userdbpw | userdb kayonmail set imappw
|
Then compile the database:
Now add authuserdb to the authorisation methods allowed and restart
the authdaemon:
# emacs -nw /etc/courier/authdaemonrc
authmodulelist="authpam authuserdb"
# wajig restart courier-authdaemon
|
Swap the order of the authpam and authuserdb if you want to check the
userdb before the system password, as might be the case when your
``virtual'' username is the same as your real username. Note that the
system password will also still be accepted! Thus, to avoid making
that mistake, it might be best to go with a different username.
However, this doesn't really fix the problem since you might simply
forget and still type your system password, and it will work! You
could drop authpam altogether and all users will then need to be added
to userdb.
You can then check that the user and password work with a telnet to
the server as described above.
To remove a user from the database:
# userdb kayonmail del
# makeuserdb
