Description
<originally posted to fwgeneral>
Problem 1:
First the rfc states lines have a 76 character (encoded form) hard limit in length. This limit while implemented isnt working quite right. Lines regularily reach 80 chars.
This is due to the tack on of the =20 after the split (see second line) the other lines I think are over by one character but I might just be counting wrong.
IE:
man",Times,serif; color: #666; margin-bottom: 5px; line-height: 1.5em; borde=
r-bottom: 1px solid #ccc; font-size: 20px; margin-top: 10px; }=0A=09=09h2 {=20=
font-size: 14px; color: #666; margin-bottom: 10px; line-height: 1.5em; borde=
Problem 2:
= line endings, aka soft breaks.
Im not sure why, and I dont see in the RFC any explanation but my email clients all have a problem with the following line ending scenario
An encoded entity, followed by a softbreak, immediately followed by another encoded identity
Eg
=09=09US<br />=0A=09=09=09=09=09Phone #: 1<br />=0A=09=09=09=09=09=09=09=09=
=09</p>=0A=09=09=09</td>=0A=09=09=09<td style=3D"width: 50%">=0A=09=09=09=09=
This will always result in an = sign being printed on the line below Phone #:1<br />. My intutition is that if the following line begins with an identity, the soft-break = should be omitted, though I cant find anything in the rfc to back this up.

It possible to get the spam cleared out of here 
And maybe even get the scheduled release bumped up

Update.
Chanign the line ending from \r\n to \n by itself resolves this error in a functional way. The new resultant output however, appears RFC invalid.
A temporary fix is
