330664 - Mail headers Content-Type and Content-Disposition are not conform to RFCs 2045 and 2231

Status: RESOLVED DUPLICATE of bug 323318

(Thunderbird :: General, defect)

Description

[devconsole]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.1) Gecko/20060226 Debian/1.5.dfsg+1.5.0.1-3 Firefox/1.5.0.1
Build Identifier: Thunderbird 1.5 (Windows/20051201)

I have received an e-mail from Thunderbird 1.5 that contains the following headers (in an attachment):

Content-Type: application/vnd.ms-excel;
 name*0*=ISO-8859-15''R%FCckstellung%20DB%2C%20DZ%20u.%20KommSt%202001-2004
 name*1*=.xls
Content-Transfer-Encoding: base64
Content-Disposition: inline;
 filename*0*=ISO-8859-15''R%FCckstellung%20DB%2C%20DZ%20u.%20KommSt%202001-
 filename*1*=2004.xls

The header parameters name*0* and filename*0* should be terminated with a semicolon (";") because of RFC 2045 which defines:

content := "Content-Type" ":" type "/" subtype
                *(";" parameter)

RFC 2231 says that "the mechanism MUST NOT change the syntax of MIME media type and disposition lines...". Therefore the semicolons are mandatory.

Please check also the errata of RFC 2231 which includes the semicolons in all examples: http://ietfreport.isoc.org/idref/rfc2231/

Reproducible: Always

Steps to Reproduce:
1. Create an e-mail and attach a file with a very long filename that contains special chars
2. Send the e-mail to yourself
3. View message source

Actual Results:  
E-mail contains "folded" parameters in Content-Type and Content-Disposition that are not terminated by a semicolon (";")

Example:
Content-Type: application/vnd.ms-excel;
 name*0*=ISO-8859-15''R%FCckstellung%20DB%2C%20DZ%20u.%20KommSt%202001-2004
 name*1*=.xls

Expected Results:  
Content-Type: application/vnd.ms-excel;
 name*0*=ISO-8859-15''R%FCckstellung%20DB%2C%20DZ%20u.%20KommSt%202001-2004;
 name*1*=.xls

Should be fixed in nighty builds (branches and trunk).
