(Exchange 2003) I have had some complaints that emails aren't being received. On one message, the outside user sent an email to four exchange users. He put all four email addresses on the To field. The message reached two recipients. Having put the Tracker on i found the email. Its log says it was delivered to the two recipients, but in the recipient list, the other two were missing. Opening the email, the To field has all four emails. Its like the bit in the middle doesn't want to know about the two recipients. This has happened on several occasions. Interestingly, the two that it happens most with are both with Hotmail.Thank youJames Carter

So you mean to say you can send to four email addresses on yahoo or gmail but not on hotmail??Check if you can send individual emails to hotmail? See if you are black listed by hotmail?Raj

What you should be looking for is the "RCPT TO"commands from the sending server in your SMTP log files. If the RCPTTO was accepted by your server it sent a 250 status to the sendingserver. If it sent a 4xx or 5xx status code the recipient addresswasn't accepted.---Rich MatheisenMCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
