The weirdness continues. I've tried to work this down to a repeatable case -
and seem to have found one. The following code is a console app:

using System;
using System.Web.Mail;

namespace SmtpWeird?
{
class Class1
{
[STAThread]
static void Main(string[] args)
{
SendThis?("bad”,

“xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx=xxxxxxxxxxxxxxxx.xxx
x”);
}

static void SendThis?(String subject, String body) {
MailMessage msg = new MailMessage();
msg.To = “anyone@anydomain.com”;
msg.From = “me@us.com”;
msg.Subject = subject;
msg.Body = body;
SmtpMail?.Send(msg);
}
}
}

You can send it to any email address -- I tried a few different ones to make
sure there wasn't anything funky on a specific server.

When the string arrives in the email, the period is missing:

------->8------------->8---------------
From: webmaster@company.com
Sent: Tuesday, November 12, 2002 9:20 AM
To: devtest@company.com
Subject: bad

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx=xxxxxxxxxxxxxxxxxxxx
------->8------------->8---------------

The length of the string seems important (add or subtract a single x up
front and it works fine). The equals sign is also important - replace it
with an ‘x’ and the problem goes away. The problem string is 76 characters
long -- does SmtpMail? do any word-wrapping for plain text? Does it break @
76 characters and that's what causes this? It doesn't matter if there's some
up front text either -- the following has the same problem:

SendThis?("bad”,
“some up front stuff
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx=xxxxxxxxxxxxxxxx.xxxx
”);

The position of the period matters as well. Move the period to the right
just one character - and it works okay.

I have not tried this with another SMTP server, just the default one on our
dev IIS box -- dunno if it would matter there.
