Thanks for a bug report. I do not think it's Evolution's bug, because the Subject line > Subject: Çàêàç ñ dom-buketov.ru needs to be properly encoded, which it is not. I guess it's windows-1251 encoding, not UTF-8, which makes the question marks appear. Even the X-Spam-Status header claims that the subject needs to be encoded: > X-Spam-Status: No, score=-0.9 required=5.0 tests=BAYES_00,HTML_MESSAGE, > HTML_MIME_NO_HTML_TAG,MIME_HTML_ONLY,RDNS_NONE,SUBJECT_NEEDS_ENCODING > autolearn=no version=3.2.5 The header should look like: > Subject: =?UTF-8?Q?=D0=97=D0=B0=D0=BA=D0=B0=D0=B7?= =?UTF-8?Q?_=D1=81?= > dom-buketov.ru I do not know if you redacted any headers in the message, but if not, then a bug report should be filled against: > X-Mailer: my_sender which might be the e-mail client which the sender uses. Interesting is, that the full headers show the Subject properly, while the collapsed headers not. I can see it here too. The message source (shown in evolution) removes those unencoded letters from the subject completely.
Milan, I am not redacted any headers. I received such messages via gmail.
OK. I do not know what mailer signs itself as my_sender, and searching for it using Google yields to nowhere, because that are too genetic words, but that's the mailer which should be fixed, from my point of view.
Milan, It is not mail client, it is site script which generate such headers (probably PHP script).
