We use Google Apps and on most domains, have a catchall address.
Over the years though, various email addresses of ours have ended up on various sold email databases/lists and they receive different types of spam on a regular basis - in fact, it isn't necessarily spam, but just cold calling via email.
In many cases, we know that the only way the some of the email addresses were obtained were through purchasing email lists, which we are very much against in business.
I am wondering if there is any way to bounce only emails to specific email addresses so that we can still keep our catchall running.
Anyone know if this is possible, either within Google Apps or with a third party app?
