Email formatting error

[mateusztylec]

I created docker container and setup SMTP properly. I send some emails for testing and there is the result.

Source of email send by osticket looks like that :

From: =?utf-8?Q?[Example]=20Customer=20service?= helpdesk@example.pl
Subject: =?UTF-8?Q?Re:=20test2=20[#173295]?=
In-Reply-To: 0f7e027e-7e12-c770-0ce3-fd1557b7b1b7@example.pl
References: 0f7e027e-7e12-c770-0ce3-fd1557b7b1b7@example.pl
X-Mailer: =?UTF-8?Q?osTicket=20Mailer?=
To: =?utf-8?Q?d?= admin@example.pl

Google and other mark that email as potential spam because it shows that "From" is wrongly formatted. I would expect something like that:

From: [Example] Customer service helpdesk@example.pl
Subject: Re: test [#173295]
In-Reply-To: 0f7e027e-7e12-c770-0ce3-fd1557b7b1b7@example.pl
References: 0f7e027e-7e12-c770-0ce3-fd1557b7b1b7@example.pl
X-Mailer: osTicket Mailer
To: admin@example.pl

I don't know nothing abount php so can't figure out where is the problem but it must be something with utf8 encoding.

Hi. What makes you believe that the issue is specific to this image?
