IMAP Service my doubts

[bisana]

Hi
My alfresco instance runs fine with no error after I configured IMAP settings in 'alfresco-global.properties', this is what I have added

imap.server.enabled=true
imap.server.port=143
imap.server.attachments.extraction.enabled=true
imap.mail.from.default=alfresco@demo.alfresco.org
# Default IMAP mount points
imap.config.home.store=${spaces.store}
imap.config.home.rootPath=/${spaces.company_home.childname}
imap.config.home.folderPath=Imap Home
imap.config.server.mountPoints=AlfrescoIMAP
imap.config.server.mountPoints.default.mountPointName=IMAP
imap.config.server.mountPoints.default.modeName=ARCHIVE
imap.config.server.mountPoints.default.store=${spaces.store}
imap.config.server.mountPoints.default.rootPath=/${spaces.company_home.childname}
imap.config.server.mountPoints.value.AlfrescoIMAP.
mountPointName=Alfresco IMAP
imap.config.server.mountPoints.value.AlfrescoIMAP.modeName=MIXED

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Now after restart my catilana.log does not throw errors, so I assume my IMAP setting is fine,
Now when  configured my 'thunderbird' to connect to ALfresco IMAP it is not connecting, it throws a message 'Could not connect to mail server , connection refused', this means my mail client cannot connect to the IMAP Server.

Now for the purpose of trouble shooting from my desktop, I tried to telnet to alfresco server on port 143, this time also I am getting a message connection refused, as shown below

telnet  192.168.0.89 143
Trying 192.168.0.89…
telnet: Unable to connect to remote host: Connection refused
‍‍‍‍‍

So there was no IMAP service running in my Alfresco server, even though I had done the correct changes in 'alfresco-global.properties', now my doubt is that
   (a) Should I have IMAP services(sendmail or Postfix or simillar dovecot,cyrus ) running at my alfresco server
   (b) When we configured CIFS, there was no need to for the system SAMBA to be configured, Alfresco had its own service running and we redirected the ports using  IPTABLES, Do we need to do something simillar over here,

As far as I know We do not need to have any extra service running

I do not see this entry in your file
imap.server.host=localhost

where localhost needs to be replaced by the ip.

Hi Mitpatoliya
Your feedback was valuable, I changed it and when I started the service as root I was able to get some progress.
Now my thunderbird tries to get connected and it gives message

The current operation on 'inbox' did not succed. The mail server account admin@dm responed invalid command

What would be the possible reason
Guidance requested.

Thanks mitpatoliya
The above problem was because the imap client(thunder bird) was looking for the folder 'Inbox' to subcribe.
I tried with OutLook express and it worked.
Now I am able to move or copy  emails to DM folders using outlook
