Change bse64 encoding to no encoding for sending email

[GoogleCodeExporter]

I send email in normal mode 
but when your email be in another language except English and have Unicode 
characters then it break up in some email clients that not support encoding and 
shows strange characters like Windows 8 mail client -  Windows phone mail 
client - some clients on android and IOS (sometimes title changed to only 
?????? ???? ???)

it only works correct on webmails 
for example i have newsletter that it should be look like this:

but it shows in strange characters (and it's not related to change encoding to 
UTF-8 character in mail client i tried that it was)

That only changes is in header of email that is:

--n91hmGOjQBEtGJ9a
Content-Type: text/html
Content-Disposition: inline
Content-Transfer-Encoding: base64

...

I know that base64 is standard but that clients (most of them are Microsoft 
products are not)
So some of my members can't read newsletter 
So if there any way to change this encoding to 7bit or normal html with no 
encoding because newsletter is not very important in security so it would be 
great

Added a 5th filed with -attach to specify the encoding
 type. The default encoding type is base64. If no encoding should be used,
 specify the 5th field as "none". Also 4th field must be specified as "none"
 if no content-id will be used. Eample:
 -attach "file.txt,text/plain,a,blah.txt,none,none" -cs utf8

Hi 
I got this error:
Error: Invalid string specified with -a 
"filec.html,text/html,i,filec.html,none,none,none"

send_type='filec.html,text/html';

it's my command i use:
mailsend -from "$from"  -smtp "$smtp" -auth-login -port "$port" -user "$user" 
-pass "$pass" -sub "$subject" -log mail.log -d "$domain" -rt "$replayto" 
-attach "$send_type,i,filec.html,none,none,none" -cs "UTF-8" -list "$list"

also i tried with
"$send_type,i,none,none,none"

Maybe i should change something in smtp.c or change base64 with another things ?

it's not important for me it support base64 encode in this case 
if i can change something that it doesn't encrypt and send email in normal html 
my problem solved 
Could you give me some thing do it? such as comment some line or change some 
line ?
