I cannot send e-mail to an address at columbia.edu using SquirrelMail??? Please help.
This is the error message I receive everytime:
Reporting-MTA: dns; plunder.dreamhost.com
Arrival-Date: Sat, 8 Mar 2003 12:28:42 -0800 (PST)
Final-Recipient: rfcXXX; XXXX@columbia.edu
Diagnostic-Code: X-Postfix; host send-multi-vif.cc.columbia.edu[220.127.116.11]
said: 550 5.7.1 Access denied
HOWEVER, I am able to send to the same address using my outlook express with the smtp set up of mail.mydomain.com.
Does the error message mean that columbia.edu has blocked the web based routing IP from dreamhost. what’s going on here?
Can we fix this?
any help or comment regarding this issue is greatly appreciated.
