I'm using Mime::Lite to create and send E-Mails. Now I need to add support for S/Mime-encryption and finally could encrypt my E-Mail (the only Perllib I could install seems broken, so I'm using a systemcall and openssl smime), but when I try to create a mime-object with it, the E-Mail will be broken as soon as I set the Content-Transfer-Encoding to base64. To make it even more curious, it happens only if I set it via $myMessage->attr. If I'm using the constructor -new everything is fine, besides a little warning which I suppress by using MIME::Lite->quiet(1);
Is it a bug or my fault? Here are the two ways how I create the mime-object.
Setting the Content-Transfer-Encoding via construtor and suppress the warning:
MIME::Lite->quiet(1);
my $msgEncr = MIME::Lite->new(From =>'me@myhost.com',
To => 'you@yourhost.com',
Subject => 'SMIME Test',
Data => $myEncryptedMessage,
'Content-Transfer-Encoding' => 'base64');
$msgEncr->attr('Content-Disposition' => 'attachment');
$msgEncr->attr('Content-Disposition.filename' => 'smime.p7m');
$msgEncr->attr('Content-Type' => 'application/x-pkcs7-mime');
$msgEncr->attr('Content-Type.smime-type' => 'enveloped-data');
$msgEncr->attr('Content-Type.name' => 'smime.p7m');
$msgEncr->send;
MIME::Lite->quiet(0);
Setting the Content-Transfer-Encoding via $myMessage->attr which breaks the encrypted Data, but won't cause a warning:
my $msgEncr = MIME::Lite->new(From => 'me@myhost.com',
To => 'you@yourhost.com',
Subject => 'SMIME Test',
Data => $myEncryptedMessage);
$msgEncr->attr('Content-Disposition' => 'attachment');
$msgEncr->attr('Content-Disposition.filename' => 'smime.p7m');
$msgEncr->attr('Content-Type' => 'application/x-pkcs7-mime');
$msgEncr->attr('Content-Type.smime-type' => 'enveloped-data');
$msgEncr->attr('Content-Type.name' => 'smime.p7m');
$msgEncr->attr('Content-Transfer-Encoding' => 'base64');
$msgEncr->send;
I just don't get why my message is broken when I'm using the attribute-setter. Thanks in advance for your help!
Besides that i'm unable to attach any file to this E-Mail without breaking the encrypted message again.
