Has anyone had issues setting up a mail reciever?

[Administrator]

I am trying to set up a mail receiver so when an email comes into a particular address it creates a ticket in JIRA. I have done this in the past in other systems without issue but I am getting an error that states Unfortunately JIRA couldn't connect to the mail server. Here is what the mail server said: "220 ***************.com Microsoft ESMTP MAIL Service ready at Mon, 5 Feb 2018 08:12:02 -0600" for help resolving the issue. This appears to be connecting in someway and the ports are correct but it is not actually letting me connect it.

I think my mistake was the port on this one this should have been an IMAP connetion but somehow I got port 25 in there, once this was resolved I still cant connect but now it is just showing connection refused, I believe this may be an issue with my firewall.

... or the server doesn't listen on IMAP port but on POP3 port. Also for both protocols there are 2 standard ports each available - one secure and one insecure.

Dear @Administrator,

I assume, that you entered  the right credentials, activated encryption like you would do to connect from a mail client.

To be sure, try a connect for m the command line of your Jira server. following this article, assuming the protocol is imap.

So long
