The forum allows users to subscribe to email notifications, so that they get a message when a new topic or reply is posted.
There seem to be weaknesses in the way html mails are generated. Under certain conditions the outgoing email looks very ugly.
Is there any way to proof read or preview the outgoing email before posting (and thereby sending the notification email)?
Not really, since it takes the content of the post.
My guess it's it could be some particular bbcode breaking something.
If you have some of these ugly emails and you can share them, then we can try to have some more reasoned guesses.
Another example is the handling of the forums' very own email that went out, if someone replies via email.
