DISCUSSION: Block Sender / Mark Spam Functionality
Problem reported by J. Dikkenberg - June 15 at 6:11 AM

Hi,
 
I am not entirely sure if I translate the message correctly, but I have just migrated an end-user to Smartermail. 
The end-user (via IMAP) can retrieve the email, but cannot send an email. Their address is marked as spam says the message.
 
I did saw 29 connections from his IP address, but I do not think that should be the problem, because he is not on the IDS list.
 
So my question are:
1) Where can I see which users get this message, i.e. are blocked to send?
2) And how can I fix it for this user?
 
Some details:
- Smartermail 16 latest version, new server with just 5 customers at the moment.
- I did start a mailbox Migration via IMAP but I don't know if this maybe happened immediately 
- The message occurred in Windows Live Mail as wel as in Outlook 2010.
- Only this customer does get this warning.
- Via the webmail sending works just fine.
 
Edit: I now see the message in the mail client: 550 No Such User Here
 
Edit: found it already, only referencing 'mx' in the SPF is not enough, like so: 
v=spf1 mx ~all
 
I had to add the full ipaddres like this:
v=spf1 a mx ip4:123.123.123.123 ~all
