Hi guys. I've just installed SBS2003 R2 so I am running Exchange 2003 Sp2. Prior to this was using Outlook 2003 as a pop3 client and using ISP SMTP to send emails to all our customers. Am really happy overall but ....
a) some (only a few) customers since we changed to Exchange say that our email to them is either always or intermittently getting put into their spam system. My question would be that our sending email address is the same so why would this be? Is it because in some subtle way Exchange delivery is different from the old ISP way?
b) perhaps related to the above. I am getting more of the following delayed delivery reports eg;
This is an automatically generated Delivery Status Notification.
THIS IS A WARNING MESSAGE ONLY.
YOU DO NOT NEED TO RESEND YOUR MESSAGE.
Delivery to the following recipients has been delayed.
My question here is; is this possibly an indication that our email to them is being treated as spam also? I though that all spam engines either rejected or accepted email, but is there a possiblity they might 'ignore' it thus triggering these delayed delivery reports?
Any help on these probably linked questions would be much appreciated!
