Oh, cool! There was also #1979, which was closed because we called it out of scope. But then there's also #1539 too, which is still open.

The underlying issue for #1979 and #1539 is that we always send Markdown-rendered emails, but some users can only receive plain text. And yes, they've reported it to us as a bug.

The fix you've made here will arguably make plain text messages a bit worse. Would you be open to augmenting this fix to also do the following?

1. Create 2 copies of all messages we send: Markdown and Plain Text
2. Modify our email sending code to send a multi-part message, with both HTML and Plain Text formats

This would probably require ditching MarkdownMailer, but that's fine with us.

Sure - as far as I know the MarkdownMailer converts the markdown to html, right? So I would remove the MarkdownMailer and use another component for Markdown to HTML translation and also provide a pure Plain Text mail and send both as multipart message, right? Just to make sure I understand everything.

Is there currently a Markdown renderer included in the project? If not: Which one do you prefer?

I think you are correct. MarkdownSharp is probably what we would prefer for now, as it's what MarkdownMailer used.

Thanks!

I got some time to work an this issue. Hope I find some more time on the weekend for the desired functionality.

Sorry for being late. Current situation: I removed the MarkdownMailer Package, but I included the Source Code from @half-ogre.
My plan is to extend the IMailSender Send-Method. Current implementation:
void Send(
string fromAddress,
string toAddress,
string subject,
string markdownBody);

Idea:
void Send(
string fromAddress,
string toAddress,
string subject,
string plaintextBody
string markdownBody);

And then add the needed pure PlainText mailings, which can be totally different to the markdown => html mailing

I'm not an email expert, but currently there should already be a plain text mailing - the pure text in markdown syntax should be there as plaintext:

        AlternateView textView = AlternateView.CreateAlternateViewFromString(
            markdownBody,
            null,
            MediaTypeNames.Text.Plain);
        mailMessage.AlternateViews.Add(textView);

        AlternateView htmlView = AlternateView.CreateAlternateViewFromString(
            htmlBody,
            null,
            MediaTypeNames.Text.Html);
        mailMessage.AlternateViews.Add(htmlView);

Should I continue and add the plaintext parameter?

@robertmuehsig, Thanks for signing the contribution license agreement so quickly! Actual humans will now validate the agreement and then evaluate the PR.

Thanks, DNFBOT;

Is this pull request still interesting?

@xavierdecoster can you please review?

Bump!

@qianjun22 this is an ancient PR, can we please figure out if we want it and merge ?

Closing this PR since it's very old and has a lot of merge conflicts.

Is this something that is still a problem? I could create a new PR.

This: #1635 is still open, and I couldn't find any indication in the code that it was.. a new PR will be great.
