Att rejects emails
We have had a Windows SBS 2008 Exchange Server 2007 for more than a year now running decently. One staff member has been trying lately to send emails to a contact but she keeps getting the rejecting message below. The recipient added us to his safe list as contacts but it did not help. We have more than 10 email accounts set up in the server for our staff. The funny part is that we tried sending an email to the same recipient from another email address from our same domain and it does work; it was not rejected. It rejects only from my coworker email address... please help. This is mining our productivity...

It’s plausible that the sending e-mail account has been blocked, or there is something in the context of the message that is causing the recipients SPAM service to block your message. You mention that you successfully sent another e-mail from another account from the same domain, but was the context identical?
#554 Denied --I've seen this message before and it had something to do with the recipient SPAM system.

Probably some additional research must be done:
Try sending FROM the same user again, but to DIFFERENT recipient under the same target organisation/server. Maybe send to recipient's co-worker would be the best test:
- if he/she will receive the message, then problem is at original recipient's CLIENT
- if neither this message is received, then problem lies within receiving SERVER nbfkord-smmi21.seg.att.com
If recipient CLIENT problem:
Let her disable SPAM checking in Outlook, just for test:
JUNK --> JUNK E-MAIL OPTIONS --> No Automatic filtering
If server problems:
Contact mail master responsible for nbfkord-smmi21.seg.att.com
Since it is not public domain, I cannot provide further help here.

Oups...one other thing:
Code 554 Denied is for SPAM, which means, that:
- either sender's LAN IP might be blocked because of high send-out spam rate, or infection with some malware
- either message itself might look like spam (maybe some links or images in signature, which are NOT added when sending out from co-worker's computer)
