The codes are MIME codes for soft returns in the text. Microsoft Outlook and
Novell Groupwise clients both do this. Listserv is strictly RFC-compliant and
so does not convert these codes to actual hard returns (CR-LF). This can
cause weird formatting problems for mail readers that interpret these codes,
but then encounter the hard returns that Listserv inserts at the end of every
80-character line.

To solve this problem, you could configure your mail server strip out the
MIME codes. I'm not sure if it is possible to get Outlook to send in plain
text, but Groupwise clients can be made to send through a non-MIME gateway.

Several users seem to encounter an issue where their e-mails are having
extra characters added to the ends of each line.  I'm not certain, but it
seems to mostly affect Outlook users.  They'll either have an equals sign
or an equals sign and some other characters following it (e.g. --  =20 or
=3D) at the end of each line.  Does anyone know the cause of this?  What
setting would cause/remove that problem?  Does it have to do with the
client sending HTML or some other styled formatting tags embedded within
the message?
