Mailserver Connection for Mail Inquiries (Jira Helpdesk)

[Tristan Fuchs]

Hi,

we can't connect to our mailserver with jira helpdesk, since a couple of days. Jira Helpdesk returns the following error message (Project Settings -> E-Mail-Inqueries):

>>Unfortunately JIRA couldn't connect to the mail server. Here is what the mail server said: "SSL peer shut down incorrectly"<<

We are using "Secure IMAP" and the login credentials are correct (tripple checked)

I managed to fix the problem. It seems the IMAP Service on our Exchange Server had an issue.

[...] The initial idea to restart the IMAP services on the exchange does not fix the problem. (In this case all the exchange roles reside on the same server) 

Run the following command (edit) on the exchange management shell
Get-HealthReport <servername>  | where { $_.state -eq “Offline”}

It will return an offline IMAP.Proxy healthstate.

Usually this is a Microsoft bug, since it appears after installing a Cumulative Update on the Exchange Server. By setting online the IMAPProxy, the IMAP service comes into life. Run the following command:

Set-ServerComponentState -Identity <servername> -Component IMAPProxy -State Active -Requester HealthAPI

This worked for me! Thanks for the find!

This suggests Jira is using a protocol for SSL that the mail server does not understand/support.  What protocols does the mail server support for SSL?
