I've just tried to download to build Zimbra but am being refused. I've cut and paste below what I've used, plus some info on what I'm connecting from and showing I have connectivity.

[root@postpostie Download]# export P4PORT=codes.zimbra.com:2666
[root@postpostie Download]# mkdir -p /home/public/p4
[root@postpostie Download]# ./p4 -u public -P public1234 -c public-view sync -f //depot/zcs/BRANCH/GNR-602
Perforce client error:
Connect to server failed; check $P4PORT.
TCP connect to codes.zimbra.com:2666 failed.
connect: codes.zimbra.com:2666: Connection refused
