There is a site on Drupal 7 + CommerceKickstart. Installed modules Mail System, Mime Mail. The problem is that when a letter comes to users from the site for password recovery, the “From” field is displayed in base64-encoding, such as =? UTF-8? B? 0JjQvdGC0LXRgNC90LXRgi3QvNCw0LPQsNC30LjQvSDQvNC + 0LTQvdC + 0Lkg0 =

In which direction to dig? Played with the settings in Drupal - does not help. Just the scripts from the server send completely normal letters, without this perversion.

Ps. The PHP mail () function is used, the server sends via Exim4.

  • Start by viewing in another client. perhaps it makes sense to attach the source text of the letter. - aleksandr barakin
  • It does not depend on where you look - in the mail / yandex browser interface or in Thunderbird. And where to get the source text of the Drupal letter that is automatically generated? - NDanilov2015 4:34 pm
  • in the client. For example, in the Yandex web interface, this is called “letter properties”. - aleksandr barakin
  • Attached in the original message. (Only HTML tags are not displayed even with "pre") - NDanilov2015

at a minimum, both the sender header and the from header are coded twice .

I have at hand a simple perl-e script that decodes strings encoded according to rfc2045 :

 #!/usr/bin/perl -CAO use Encode qw(decode); $na=$#ARGV+1; if($na==1) {print decode("MIME-Header","$ARGV[0]"),"\n"} else {while (<>) { print decode("MIME-Header",$_); }}

it can be passed encoded either to stdin , or as the first argument.

decoding, for example, the sender header:

 Sender: =?UTF-8?B?Ij0/VVRGLTg/Qj8wSmpRdmRHQzBMWFJnTkM5MExYUmdpM1F2TkN3MExQUXNOQzM=?= =?UTF-8?B?MExqUXZTRFF2TkMrMExUUXZkQyswTGtnMExZPT89CiA9P1VURi04P0I/MExYUXY=?= =?UTF-8?B?ZEdCMExyUXZ0QzVJTkMrMExUUXRkQzIwTFRSaXlEUXVDRFFzTkM2MFlIUXRkR0I=?= =?UTF-8?B?MFlIUmc5Q3cwWUE9Pz0KID0/VVRGLTg/Qj8wTDdRc2c9PT89IiA8emFrYXpAZW4=?= =?UTF-8?B?bmVsaS5ydT4=?=

we receive instead of the text:

 Sender: "=?UTF-8?B?0JjQvdGC0LXRgNC90LXRgi3QvNCw0LPQsNC3 0LjQvSDQvNC+0LTQvdC+0Lkg0LY=?= =?UTF-8?B?0LXQv dGB0LrQvtC5INC+0LTQtdC20LTRiyDQuCDQsNC60YHQtdGB 0YHRg9Cw0YA=?= =?UTF-8?B?0L7Qsg==?=" <zakaz@en neli.ru>

similar picture with the title from .

those. the solution in your case is to find that place in the code that forms the letter in which the second (or the first, depending on where to start the counting) encoding is performed. I suspect this happens somewhere during the preparation of the letter before calling the mail() function.

  • Hooray, I solved the problem! See above my answer) Thank you so much! - NDanilov2015

Yes, really coded! I solved the problem. The casket just opened, the module just needs to update Mime Mail. This is a famous glitch in one of the versions: No. 1908318 by jvieille, zionduc, bisonbleu | anrkaid: Sender is double encoded https://www.drupal.org/node/1908318
