IMAP,POP3 Health Monitor setup issues
Hi all,
i am fairly new to F5 and trying to setup a health monitor for a node with POP3 and IMAP services.
i am using the IMAP and POP3 template available in F5.
i supplied it with all the information required but it just checks for few mins and then fails.
can someone please guide me on this.
thanks, Sudhir

Type: IMAP Parent Monitor: imap Interval: 10 seconds Up Interval:Disabled Timeuntill Up : 0 Timeout: 31 seconds Manual Resume: No User Name: username Password: ********** Folder: INBOX Alias Address: * All Addresses Alias Service Port: * All Ports Debug: No
my nodes are setup to accept traffic on 443 and when i access the node from browser i am able to login using the credentials.
thanks
Hi,
Your nodes are likely listening on 443 for web based access, and on the specific POP3 and/or IMAP ports (defaults 110 and 143).
If you set up your VS and pool members to load balance 443 traffic and associate a default IMAP monitor, this latter will check on the 443 member port. So in your case you are talking IMAP on 443 port which will not work.
If the logic you want to implement is to provide web access to your users but do the health check on the IMAP status, then you have to change the "Service Port" parameter in your monitor and explicitely specify your IMAP port instead of *, this will override the member configured port.

I suggest you set Debug to Yes in the monitor, and then check the created log file in /var/log/IMAP__XXXXXXXXXX (I'm not sure of the name but It will include the IP+port of the members)

hi Amine,
sorry for the late response, i have setup the Debug option but not able to browse to VAR/Log folder. can you please guide me how can i do that
- You didn't give the issue you are facing, maybe you didn't use a root account to access the CLI. SSH to F5 and log on with the root account, then browse to /var/log.

i was able to make the IMAP monitor work by enabling plain text authentication on the server.
but my requirement is to use secure SSL/TLS connection to authenticate with servers.
can we add SSL/TLS certificate to the IMAP/POP3 monitor?
i tried digging in but could not find anything.
any help will be really appreciated
thanks,
