Summary:                    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".

Only reason is because it needs to be reviewed and committed. As you may
have noticed we have over 600 open issues, so time and resources are pretty
much the only reason for delay. Your patience is greatly appreciated!
