Summary:                    [patch] Asterisk produces malformed email files for
voicemail
Description: 
Asterisk is inserting an extra <cr> into the voicemail attachment.  This
causes some mail relays to fail to forward the SMTP message.

While the correct line termination in an SMTP message IS <cr><lf>, the
conversion from the Unix <lf> line terminator to <cr><lf> is handled by
sendmail.  When sendmail gets a file which (mostly) has just <lf>
terminators up until the attachment, it sees the <cr><lf> in the attachment
portion and converts that to <cr><cr><lf>.  This confuses some mail relays
down the road and prevents delivery.

This is a problem in all versions, and the fix is trivial:

At line 418 of the current head, there appears

#define eol "\r\n" 

this should just be "\n"

The resulting SMTP message will still have <cr><lf> once it has been
processed by the sendmail command.

"eol" is used ONLY in "ochar" which is used only in "base_encode".
