What are you using for an email server or service vendor? You need to contact the vendor to support you with email relay issues
If you are using G Suite or Gmail any other vendor with 2FA settings you will need to create an app password:
Log in your Gmail account and access the following link
Go to security and click the app password.
Select the app or Give a custom name that makes sense to you and click generate, now use that app-specific password in your osTicket

We use hMailServer we control the server, and everything is fine, we use many third party software to receive and send emails, but Osticket can not authenticate.

yozdas did you solve it? I have the same problem

One of your screenshot says: that means you might have checkbox selected No under email settings
"code: 550 SMTP AUTH is required for message submission on port 587"

Another screenshot: you have selected the checkbox: Use Separate Authentication
Unselect that

krvam not yet but made some progress regarding the error.

ramrajone i tried every options on settings nothing worked, so made a very long research and i think found the problem, problem is we have another MX record on the server of Mailing company but the priority is less than our records, Our records priority is 10 but Mailing company's priority is 20 some how test mails goes to mailing company and SMTP tries to Authenticate to Mailing Company's Server.
But the thing is OsTicket was not acting like this before moving to it's new server, would it be OsTicket Host server problem?

The MX record is to deliver the messages, lower the Priority it uses that, if that fails then goes to next
osTicket doesn't control that

Your message clear error "550 SMTP AUTH is required for message submission on port 587" means you have checkbox not selected for your email setting that it requires AUTH.
Take a new screenshot of your email settings and post it

i receive this error ;

thee 550 you mention is because it could not deliver the message because i use SMTP sending option not PhpMailer option.

on Old server i was receiving 550 Error but mails were delivered with PhpMailer.

Screenshots as you asked;

Mailing Company the one which hold second MX record with priority 20 says; "it does not suppose to act like this, the second MX record is for the accounts which you do not have in your mail server, if you have the account in you mail server this should not be a problem".
And i agree with them.
This is the problem of either Osticket or OsTicket Host server problem.

Correct SMTP is the default, then PHP is fail back

Your error message is Authentication, Also you still have check box "Use Separate Authentication" un-select that
it could be number of things, hostname, type of account, firewall, etc...

yozdas

ramrajone
"Use Separate Authentication" un-selected;

it is the same, Hostname is ok, type of account is ok, firewall has no restrictions regarding this, 3rd party softwares has no problem, they can authenticate with no problem.

Did you ever have it working or is this fresh setup?
Can you try port 25 or 110 (since you are using POP service)
587 is more traditionally associated with TLS which is a more secure method of mail delivery, not sure if your server supports or not

This is not fresh install but i moved OsTicket to new server by upgrading to latest version, i did tried on Old server it did not worked also and i thought it is because of E-Mail Service Provider, so i changed service provider to our self, now we manage E-Mail server and we use 587 port for SMTP, we use Outlook, Thunderbird, some Mailing Application, some other Automated Mailing services Like on Erp Software, Email services on e-commerce web site we do not have any problem regarding managing E-Mail server, sending and receiving Emails and Authenticating any 3rd party applications.
