I've got some seriously weird ass behaviour going on in my Interspire. About 6 months ago I send a email out to about 600 people no probs. Today I come to send out to a list of 1300. I send to my test list first of 5 emails, they all inbox and work fine. So now I try to send to my list of 1300, literally non of them even send. Interspire says it couldn't send a single one out of 1300. Test the test list of 5 again, works fine. I've checked the error logs, nothing I've exported and imported into a brand new list still no luck No settings have changed. Any idea what can cause this?
