I couldn't get it to work but I'm pretty sure it wouldn't anyway.
I had a look at the MailHost code and found some quoting stuff that if I
knew more about python I might be able to do work out the problem with.

Down the bottom of MailHost.py in the MailHost product is the following

ESCAPE = '='
MAXLINESIZE = 76
HEX = '0123456789ABCDEF'

def needsquoting(c, quotetabs):
    if c == '\t':
        return not quotetabs
    return c == ESCAPE or not(' ' <= c <= '~')

def quote(c):
    if c == ESCAPE:
        return ESCAPE * 2
    else:
        i = ord(c)
        return ESCAPE + HEX[i/16] + HEX[i%16]

def encode(input, quotetabs):
    """Encode a string to Quoted-Printable"""
    output = ''
    for line in string.split(input, '\n'):
        new = ''
        prev = ''
        for c in line:
            if needsquoting(c, quotetabs):
                c = quote(c)
            if len(new) + len(c) >= MAXLINESIZE:
                output = output + new + ESCAPE + '\n'
                new = ''
            new = new + c
            prev = c
        if prev in (' ', '\t'):
            output = output + new + ESCAPE + '\n\n'
        else:
            output = output + new + '\n'
    return output

I presume some quoting needs to go on in order for the message to be sent to
the smtp server. This seems to be buggy. Can anyone tell me how to fix this
as it is quite urgent.
