We have a couple of important contacts that are using msn or hotmail accounts. In the last couple of weeks almost all our emails get returned.
Why is it that only MSN and Hotmail are having this problem vs. everyone else? [i](PS. I’ve already followed the supplied links to troubleshoot sender problems to hotmail accounts – I’m just wondering why it’s causing problems only with them. What’s the difference between their spam filters and everyone else’s?)[/i]
