@Sanjeev Thank you for your help. Really looking forward upgrade to the next version. The current swiftmailer only accept email as a username, I need to modify swiftmailer.yaml to make SendGrid working. It's a little bit difficult for the common user.

but the deprecations still worries me, is it going to make some trouble in the future?

@Sanjeev Thank you, change the URL does the same thing, but I fixed it anyway.

Here is what I did.
In /vendor/uvdesk/mailbox-component/Console/RefreshMailboxCommand.php , follow the refreshMailbox to pushMessage

The response is not 200 but an HTML turns out it is the Cloudflare returns a CAPTCHA to me instead let me visit that URL...

Thank you for your help.

Update. Fixed the send email issue. apparently, I am using the wrong port. 465 or 587 should be noticed.

The receiving email from IMAP still act like before, can read how many emails in the folder, just cannot create the ticket.

But it is fine to manually create a ticket, just cannot receive any reply from the visitor.

Stil; working on it.

Hi @Sanjeev , thank you for replying my post, the mailbox setting is referenced from https://www.uvdesk.com/en/blog/setup-mailbox-uvdesk-open-source-helpdesk/
our URL is ticket.conniglobal.com/public, which is the value of site_url in uvdesk.yaml.

Hi, I am just wondering if it is just me or it's a common thing that can be ignored.

Just installed UVdesk on a new VPS, CENTOS 7, PHP 7.2 with all the required modules, APACHE,

followed this instruction
https://www.uvdesk.com/en/blog/open-source-helpdesk-installation-centos-uvdesk/

The whole installation process is pretty smooth until I finish the setup of the emailbox.

There are around 50 deprecations in the log, I downgraded composer to 1.10 just to install the UVdesk, it probably not the issue of the deprecation.

The email cannot send out when creating the ticket, and no email if someone replies to the ticket.

The IMAP can access my Gmail account with the APP password and read how many emails are there in the inbox like this

There is no ticket created after this process either.

It is greatly appreciated if someone could provide a suggestion for me.

Thank you.
