Is there some sort of formatting protocol for html email? We have an automated system that sends reports via email, when I look at the source I see them delimited by line length with an "=" breaking the line. That is, I get something like :
<html><body>some text some text some text some=
some text some text some text some text som<ta=
ble>some text some text some text some text <t=
r><td...
Does anyone have any more information on what this is?
You have to send the message as multi-part MIME. Best practices are:
As to your garbled message, it looks to me that your message isn't being correctly identified as HTML so the mail client is wrapping lines of text at 70 or so characters.
Looks like it could be quoted-printable. How do equals symbols in the HTML look, are they replaced by =3E?
Technically there's nothing wrong with this, but it would be nice to include an alternate plain text, for those people who can't or don't want to read HTML mail (like me).
Your message is being translated somehow to "quoted printable" encoding. This is probably an issue with the mail headers you're creating.
The email RFC enforces line length limits, specifically each line should be no longer than 78 characters, excluding CRLF. The equal symbols at the end of each line is just a line delimiter, which will be correctly parsed by any email reader that supports HTML, as long as the necessary headers are in place (Content-Text: text/html).
