#56 Umlaut in subject causes a corrupt mail
Hi Ian
Since version 1.10, the mail gets corrupted when the
subject contains a umlaut(ä,ö,ü).
This is the header from a corrupted mail, the original
subject is: 'DataFormErrorState - Buttons für Farben
sind keine DnxWinControls'
Microsoft Mail Internet Headers Version 2.0

It seams to me that this only happens when the subject is
longer than 76 characters -> MailEncoder.cs line 230 ff?

Thanks Thomas, this is probably due to the encoder changes,
I'll have to dig further into it and take a look

Don't know if this will fix your problem, but apparently I never
sent in this fix. With these changes, I could send accented
subject lines up to 255 chars (I think Outlook is chopping it).
Actually, I was sending UNICODE which I know Outlook
doesn't handle in the subject so it gets "reduced" to ASCII.
OpenSMTP will only preserve unicode in the BODY if you
switch from ISO-8859-1 to UTF-8.
internal static string
ConvertHeaderToQP(string s, string charset, bool
forceconversion)
{
if (!forceconversion)
{
bool
needsconversion=false;
for (int i=0;
i<s.Length; i++)
{
if (s[i]
> 126 || s[i] < 32 || s[i] == '=' || s[i] == '?')
{
needsconversion=true;
break;
}
}
if (!
needsconversion)
{
return
s;
}
}
// TURNER.BSD MODIFIED

// appears from other
mailers that EACH line of QP must be wrapped
// also, spaces are replaced
with _
string[] lines = ConvertToQP
(s, charset).Replace("\r\n", "\n").Split(new Char [] {'\n'});
s = string.Empty;
for(int i=0; i<lines.Length;
i++)
{
// remove any
trailing '=' (line continuation tag)
if (lines
[i].EndsWith("=")) lines[i] = lines[i].TrimEnd('=');
s += "=?" +
charset + "?Q?" + lines[i].Replace(' ', '_') + "?=";
if (i<lines.Length)
s += "\r\n ";
}
return s;
}
