IMAP services:
This document contains information relating to :

  • imapd and saslauthd
  • apache2
  • mailstore

Note: Whilst we can create and manage mailboxes here - we don't add the user to the radus system - a radius entry for the username and password must be created either in daloradius or in the irax portal

cyrus imapd and saslauthd:

systemctl restart cyrus-imapd 

systemctl status  saslauthd

Config Files 

nano /etc/imapd.conf 

nano /etc/cyrus.conf

IMAP management
There are a number of ways that imap mailboxes can be managed. Below is how to do some management on the imap server
There is also the Server_manager system that provides an api to do the same - direct access using our own perl functions can be found here: 

cd /var/Smtp_service_manger/perlimap/

further detail regarding the api and its use in the Irax portal is here: SMTP Service Manager

quick reconstruct of mailbox

root@imap:~# cyrus reconstruct  -r -f  user/me@irax.com

Log into cyrus user: 

root@imap:~# cyradm  -u cyrus  localhost  -p 143

Here we can use the imap commands lm dm cm lam dam sam to manage mailboxes
so lm we can do things like

  • lm user/ian@irax.com
  • lm user ian*@irax.com
  • lm user/*@irax.com

note the use of * can be quite powerful especially with delete mailbox

  • dm /user/fred/*@irax.com

will delete all mailboxes for fred@irax.com
lam lists the acls lam user/ian1*@irax.com gives this 

localhost> lam user/ian1*@irax.com
user/ian1@irax.com:
  ian1@irax.com lrswipkxtecdan
user/ian1/Drafts@irax.com:
  ian1@irax.com lrswipkxtecdan
user/ian1/Sent@irax.com:
  ian1@irax.com lrswipkxtecdan
user/ian1/Spam@irax.com:
  ian1@irax.com lrswipkxtecdan
user/ian1/Trash@irax.com:
  ian1@irax.com lrswipkxtecdan

We could not use dm to delete this mailbox because cyrus has no ACLs
sam is 'set acls on mailbox' sam user/ian1*@irax.com cyrus all 

localhost> sam user/ian1*@irax.com cyrus  all
Setting ACL on user/ian1@irax.com...OK.
Setting ACL on user/ian1/Drafts@irax.com...OK.
Setting ACL on user/ian1/Sent@irax.com...OK.
Setting ACL on user/ian1/Spam@irax.com...OK.
Setting ACL on user/ian1/Trash@irax.com...OK.

So now the mailbox can be deleted

localhost> dm user/ian1*@irax.com
Deleting mailbox user/ian1@irax.com...OK.
Deleting mailbox user/ian1/Drafts@irax.com...Mailbox does not exist
localhost> lm user/ian1*@irax.com
localhost>

Success!
Sometimes a mailbox does not work properly. you may see a message like
Setting ACL on user/ian1/Drafts@irax.com…cyrus: lrswipkxtea: System I/O error
One way of fixing this is creating a temporary mailbox of a similar name ( and possibly its sub mailboxes. This mailbox structure can then be copied in the mailstore to the broken mailbox for example:
on the imap server: 

localhost> cm ianx@irax.com
localhost> cm user/ianx/Drafts@irax.com 
localhost> cm user/ianx/Sent@irax.com 
localhost> cm user/ianx/Spam@irax.com 
localhost> cm user/ianx/Trash@irax.com

then on the mailstore server: root@mailstore:/irax/mail/domain/i/irax.com/i/user# cp ianx ian1 -rp now back on the imap server localhost> sam user/ian1*@irax.com cyrus all now works

localhost> sam ianx@irax.com cyrus/all
