Summary0005284: Wrong charset decoding of subject field in Web mail
Description

Hello!
On this week we faced the problem with incorrect displaying of subject field in mails from one of our partners
In mail source subject field looks like this - Subject: Àáîíåíòñêèé çàïðîñ ¹259694
Source encoding iso-8859-1 should be decoded to windows-1251, but it's not working
Mail body looks fine, cause it's multipart message with preferences for every nextpath.

Here is some additional info:
OS - Centos 7
SOGo - 5.0.1.20210317
nginx 1.16.1

Message source:
Subject: Àáîíåíòñêèé çàïðîñ ¹259694
Content-Type: multipart/related; type="multipart/alternative";charset="windows-1251";boundary=c365r345e34362m34423a2472t234211o234562r67846131i24351u23423465m

E-Mail standard RFC2822 states
https://www.rfc-editor.org/rfc/rfc2822#section-2.2

"2.2. Header Fields

Header fields are lines composed of a field name, followed by a colon
(":"), followed by a field body, and terminated by CRLF. A field
name MUST be composed of printable US-ASCII characters (i.e.,
characters that have values between 33 and 126, inclusive), except
colon. A field body may be composed of any US-ASCII characters,
except for CR and LF. However, a field body may contain CRLF when
used in header "folding" and "unfolding" as described in section
2.2.3. All field bodies MUST conform to the syntax described in
sections 3 and 4 of this standard."

Therefore your subject is an invalid header entry exceeding the allowed character range.
In order to use such characters in your subject, you have to use some encoding.
See https://www.rfc-editor.org/rfc/rfc2047
