Can´t send email

J

Javier_Laurini

I have a strange problem in my networks. All my clients use MS Outlook 2000
to manage their emails through an ISA server 2000 computer. everything was
functioning properly until 2 days when 2 computers stop to be able to send
messages. The same accounts configured in any other computer of the networks
works fine. Any account configured in those computer are unable to send
messages.
The error message received says (in the data portion of the email):

Action: failed
Status: 5.7.1
Diagnostic-Code: smtp;554 5.7.1 Command rejected
on a line by itself
nder ok

..- The mail format was unchanged and is the same in all computer
..- the users have the same privbileges on the network
..- no virus where found in any computer.

We reinstall completley one of the computer but that didn´t solve the problem.
If anyone can think of any action,

THK
