If  i send  binary data ( attachment s) and if this data  is not the known
mime type ??? ( EXE, ZIP, PDF, .... )   the encoding for this data is 
quoted-printable, Sending or fetching is very problematic. 

example:
create 10m.dat test file ( or  5mb 6m, .... )
dd bs=10485760 count=1 if=/dev/urandom of=10mb.dat
run file command:   file 10mb.dat  -- > 10mb.dat: data

Sending email is very problematic - the IMP very long encoding this
attachment and CPU usage is  90 - 96 % for apache process,  WWW
browser timeouts, etc.
PHP allocated very more memory  > 128MB,  ( > 256 N if  I usind SMTP
mailer  not  sendmail) .  The email attachment is not completed -  
truncated and not reading (fetching) - data incorrect.
Email header in this email:  Content-Transfer-Encoding: quoted-printable.
If i compress the file to ZIP archive  the  sending is very fast and
email
is OK. ( fetching ok )
