Very strange. I host 3 websites on my server. For all of them I have created the co-domain webmail. etc. .tld and created the forward (using the panel) to https://www
. etc. .tld:81/squirrelmail/src/login.php
For 2 of the 3 domains this works; the other refuses to do this. I have ticked the "Create DNS" option for all of them.
The weird thing is that the full path, when entered, does work?!?!
The only difference is that I own the 2 working domains whereas the 1 that does not work is forwarded to my server from another ISP; could that be causing the problem?
