Nagios XI 5.6 Inbound Mail Server Connection Issues

Hi Support,
I just upgraded to Nagios 5.6 and tried setting up the inbound mail server but when I run a test it gives me the following error
Code: Select all
Could not connect with the inbound settings given
[CLOSED] IMAP connection broken (server response)
Do you have any idea what the issue is?
I created a new pop3 mailbox and use No Encryption, pop3, port 110, and validated the mailbox works correct via telnet.

Are you sure you have the POP3 selected in "Connection:" field on the settings?

Yes, as you can see from the attachment it's set to pop3.

I think you found a bug.
Can you edit the following file
Code: Select all
/usr/local/nagiosxi/html/includes/utils-email.inc.php
line 335 change from
Code: Select all
$conn_type = get_option('mail_inbound_conn_type', 'imap');
to
Code: Select all
$conn_type = get_option('mail_inbound_type', 'imap');
Save, then test again.
This will be fixed in the next release.

Thank you. That fixed the error I got.
However, I'm still getting another error.
Code: Select all
SECURITY PROBLEM: insecure server advertised AUTH=PLAIN
Can not authenticate to POP3 server: [AUTH] Authentication failed.
I'm wondering do you know if its because I don't have TLS/SSL enabled? I'm sure my credentials are correct.

Glad that fixed the first error.

this depends on the settings on the POP3 server.
Also, some servers use full email address for username, others do not.

Think it was due to the password not saving until you click the Update Settings so I had the wrong password in there.
However, now that the password is correct, I'm getting this error message.

Does this server allow none for Encryption?
Is that what you have set?

I'm pretty sure it does allow for it. Are you referring to the nagios server?
I ran telnet outside to test the username/password and it worked fine.
I also checked the maillog on the box and it shows
Code: Select all
dovecot: pop3(nagios_reply): Debug: INBOX: Mailbox opened because: POP3 INBOX
dovecot: pop3(nagios_reply): Disconnected: Logged out top=0/0, retr=0/0, del=0/1, size=663
So I assumed it didn't have any issues with the user account.

I meant in XI is it still set to None in the Inbound mail settings?
Did your dovecot test use no encryption?
