Actually, you'll need to take couple of steps, however they are trivial.
While you can telnet to port 110, your user will not be able to login,
and email will be delivered to the wrong place (where Cyrus can't access
it).
First thing, enable and start saslauthd. Cyrus uses it for authentication:
# chkconfig saslauthd reset
# chkconfig saslauthd on
# /etc/init.d/saslauthd start
Then, instruct Sendmail to use Cyrus for delivery to local mailboxes
(instead of default procmail). First find and comment (place "dnl "
string in front of them) these lines in sendmail.mc:
FEATURE(local_procmail)
MAILER(procmail)
Replace them with these lines:
define(`confLOCAL_MAILER', `cyrusv2')
define(`CYRUSV2_MAILER_ARGS', `FILE /var/lib/imap/socket/lmtp')
MAILER(cyrusv2)
Rebuild sendmail.cf from sendmail.mc, and restart sendmail.
You would place "define" lines somewhere around start of sendmail.mc
(where other "define" lines are). Place "MAILER" line at the end of the
file (where other "MAILER" lines are).
If you want user's mailbox to be automatically created when user logs in
for the first time, add this line to /etc/imapd.conf:
autocreatequota: -1
If you don't set this option, you would need to manually create user's
mailbox before they could login. Note that for email to be delivered to
mailbox, it must exist (in Cyrus world, mailbox and account are two
different things). So, even with that option, user would either need to
login to account or you would need to create mailbox before email can be
delivered to it.
Creating mailboxes manually is easy. Set password for cyrus account.
Excute "cyradm -u cyrus localhost", and then use "cm" command to create
mailbox. For example, to create mailbox for user root, you would do
(the "user." part is important!):
# cyradm -u cyrus localhost
> cm user.root
> exit
While in cyradm, you can type "help" to see other usefull commands.
If your users are using Outlook or Outlook Express to read email, your
life will be a bit easier if you add this line to /etc/imapd.conf:
altnamespace: 1
If your users are not using buggy IMAP clients such as Outlook or
Outlook Express, don't set that option.
You might want to browse through man page for imapd.conf ("man
imapd.conf") to see other usefull option. You probably will not want to
change anything else. One thing to warn you, "createonpost" option will
probably look tempting, but you really do not want to use it. It has
some ill side effects.
BTW, since you'll have fully working IMAP server, my advice is to let
users use it. Switching to new PC, or accessing email from webmail, or
from multiple PCs is so much easier if users are using IMAP. Even if
they need access only from single PC, there are still advantages of
using IMAP, and having email stored on IMAP server.
