[Mailman-Users] Long subject lines get extra padding from mailman

[Miles Waller]

Hi,

I have verified this problem in mailman versions 2.1.2 and 2.1.5.  The 
problem seems to be that the second and subsequent lines of a long 
header are indented when they are folded onto new lines.  From my basic 
testing, the isseu seems to be related to the presence of the indents, 
rather than the actual line breaks.

The impact is that several mail clients (tested thunderbird 0.9, outlook 
express 5.5, outlook 2000) try faithfully to display all the extra 
spaces between words, causing a gap to appear in the subject line which 
can be quite noticeable in certain circumstances.

Here is a sample of the headers:

Is this a bug in mailman, or is it something in the list settings that I can change?
Has anyone else had this problem, and how have they worked round it?

Thanks,
