Hello all, I am new here.
Here is the version of my zimbra and the OS:
Release 5.0.16_GA_2921.RHEL5_64_20090429051405 CentOS5_64 FOSS edition
AMD Phenom Quad
CENTOS 5.3 / 64-bit
Yahoo rejects my email after install, here is the error I received from Yahoo:
<my email address>: host mx1.mail.sg1.yahoo.com[220.127.116.11]
said: 554 Message not allowed -  (in reply to end of DATA command)
One of my installations(another location) of Zimbra(the latest version todate:9/2009) was having this same problem. I experimented with another re-install and remove the "proxy" module. After that, yahoo now receives my email. The version that was having this problem was the version I described above to where I am writing this post. I also re-install and remove the proxy module, but I am still having the same problem.
Any help will be greatly appreciated...
