Hi

I want to sent attachment file which is 400mb size.(single file, not tar file)
is there any way that these kind of large files can be divided into small sizes and sent as attachments

thanks with anticipation

MIME defines a content type "partial" which can be used for this. I don't think mailx has support for dividing a large file attachment into multiple partial messages, but you can construct the MIME parts and feed them to sendmail yourself.

any other alternative way of sending email attachments for large files.
its ok if i cannot used mailx.

If you want a user interface to MIME then I believe Mutt or Thunderbird might work for you, although I'm not sure if they support splitting large files into multiple messages. Personally I use Gnus which is probably too arcane if you are not an Emacs user already.
