is this a new install? please excuse me as I am not trying to offend...but just want to make sure we are in the right place and such.....
No, this is not a new install and I've had no problems before
/home/vpopmail/bin (or where ever your vpopmail home dir is) and do ./vadddomain ..so like below...
the vpopmail homedir is /var/vpopmail
#./vadddmomain testdmomain.com 123test
I get the exact same result and I don't really see what diffence it should make
