Local Exchange Server with IMAP, dont connect

aaguilara

hi, i have problems with IMAP:993 wuth exchange server local. i have debian 11 with OSTICKET 1.18, php 8.2.7

cannot connect to host; error = stream_socket_client(): Unable to connect to ssl://mailboxserver:993 (Unknown error) (errno = 0 )

In the exchange servers, Mailbox user is OK. IMAP is OK, Firewall OK

It’s saying it cannot connect to the given host/port. Maybe you have a firewall in place on either end or something? You should look at your server logs to see if that can provide more information.

Hi all, I have the same problem, basic IMAP authentication on local exchange server 2019 does not work. The same configuration works with the previous product ( Vtiger ) and I also wanted to test it with another product ( Hesk ) and it works perfectly in both cases. Having seen the results with other products, I can certainly say that it is not a problem with the mail server, it is not a problem with the user, and it is not a problem with the host on which Osticket is installed. I've read all the guides, they don't talk about basic auth problems.
This is my setup:

oTicket 1.18
php 8.2.0
Apache 2.4.54.2
mysql 8.0.31

Hostname - My mail server
port number - 993
Protocol - IMAP
Authentication - Basic Authentication ( Legacy )
Username - email address
Password - my password

All the practical advice would be useful as all the documentation has already been read.
Also the same setup, is currently in use on the old ticket management portal developed with Vtiger and works without any problem.

Can you provide more info? "It doesn't work" doesn't really help any. Are you receiving any errors when enabling IMAP and saving? Have you checked your system logs? Have you setup a cron job? Have you check your logs (general server logs, webserver error logs, PHP error logs, MySQL/MariaDB error logs, osTicket System Logs, Browser Console logs, etc.) for any related errors?

Cheers.

HI,
I did all the necessary checks, I'm not very expert but I didn't find any particular errors ( I use Wamp on Windows 2019 server ).
My problem is this:
When I try to configure the mailbox ( mailbox setting )
hostname : mail server 10.xx.xx.xx
port: 993
mailfolder: INBOX
protocol: IMAP (the other choice remains POP which I don't care about)
"Mail Fatching still disabled"
next to Authentication, there is the config item, I open and the window appears where you can enter your username and password to access your mailbox.

I insert the data that I am sure are correct, as soon as I click on save this message appears:

" cannot connect to host; error=stream_socket_client(): Uneble to connect to ssl://10.xx.xx.xx:993 ( Unknown error) (errno=0)

From this error it appears that you cannot connect to the server.
I did a test, I installed Osticket version 1.16 and with the same server and mailbox and also the same version configurations of PHP, Mysql and Apache and I have no problems, mail fetching works with IMAP.
So, from this we understand that the problem is on the version from 1.17 (I encountered the same type of problem) to 1.18, there is a bug related to basic authentication on these two versions.

I also tried upgrading from 1.16 ( which works and has no problems with IMAP email fetching ) to 1.17, but the situation doesn't improve.
IMAP email fetching on exchange on promise server with basic authentication ( Legacy ) works only on version 1.16, while it fails on version 1.17 and 1.18

You will simply need to look at the logs on the server to see why the connection is failing. I don’t have a local exchange so I won’t be able to replicate this. I will say people are using basic auth with exchange with no issues so something’s up here.

Cheers.

Hey @nazario, did you ever get it to work? I am running very similar versions to you and am getting the exact same error. It does seem to be a bug introduced relatively recently, as we had no problems with this connection on v1.16. Did you find a solution?

This answer doesn't help, I can't find anything on the server, in fact if I run Osticket 1.16 IMAP Fetching mail it works, if instead I use osticket 1.17 or higher, fetching mail doesn't work.

osTicket only gets the error you see so there is no way to tell why it’s refusing to connect from within the application. You’d have to look at the mail logs on the server to see more information as to why. If you’re using Linux it’s typically /var/log/maillog.

Cheers.
