Indicators/Notification for blacklisted emails
I've got the problem that emails are quiet often blacklisted (what I can see primary on stopforumspam). It would be great to have a footer with aditional information like "email xy is blacklisted, use another one".
A better solution would be: Personaly I'm using Gmail to fetch over POP3 my hotmail accounts. It would be perfect, that we can enter a queue of emails and SER automatically checks an email for blacklisting every few hours and if it's blacklisted it uses a new one (which is already configured in Gmail). With this strategy there could be 5 backup emails (limit of Gmail for POP3 fetching).
Atm when I don't manually check the emails for blacklisting I "risk" that SER "trashes" targets because the email is blacklisted and never try to post to this url again.
