Hello,

I would like to make an application that can send e-mails to someone when it's his/her birthday. The text can be styled.

As the Language Reference states, an EmailMessage object has these useful properties:

BodyPlainText
BodyEnriched
BodyHTML

BodyEnriched today isn't that common. If you need to support OS 9, you probably
should use Enriched.

Hmm... OS 9 is to be considered. Do you advise me to use Enriched for OS 9 anyway?

Well, I missed the point, that OS 9 supports PlainText too. In case you would like to
send OS 9 friendly styles email, you need to support EnrichedText.


All modern mail clients should be able to read PlainText and HTML - while HTML might
get marked by certain filters more likely as spam.

So, since I want to send styled mails, I have to use HTML that will be considered as spam. Well, that's a shame.

So, how does one send styled mails that aren't spam?

You simply can't.

Spam filters follow certain rules which aren't predictable in general.
I claimed, that HTML email is more likely to get marked as spam, but PlainText might
get marked too.

You should finish your application orderly and conform to email's RFC definitions. Then you are - in general - on the safe way. If emails get marked, this is mainly
related to their contents

Well, the purpose of my application was out of my mind during one moment.

In fact, if my application is running while the computer is connected to Internet, I plan to check for received messages (the user can enter, if he wants, the account information)

When my application sends an e-mail, an header is added. This header contains the name of my application. Now, if on the other side, my application is allowed to check for e- mails, I get a list of mails from the server. I check if a message has the header of my application's name (obviously, I don't take care of other mails nor delete anything on the server). Then I display the e-mail in my own application.

Therefore, I imagine I could send the styled information in a new header. If the user reads the mail using his default mail reader, it sees only as plain text. If he uses my application, it sees the styled text.

But that gives me 2 questions:

1: can headers have non-printable or high characters for an e-mail?
2: is there a limitation (e.g. in length) of an header?

If 1 is yes and 2 is no, then that's 
fine._______________________________________________
