Hello , We are able to relay the messages when the smtproutes are there , but when i add my domain to the smtproutes then it does not relays. eg my domains are prl.res.in and prl.ernet.in when i add the :prlfs.prl.ernet.in in the smtproutes , it works for all the mails which are allowed Ok thats fine , but when i add the prl.ernet.in:prlfs.prl.ernet.in then it stops relaying WHY ? . there are no spaces from the starting.
