When I try to send an e-mail using authenticationless relay via telnet, I receive an error message "553 sorry, that domain isn't allowed to be relayed thru this MTA (#5.7.1) rcpt to:
[email protected]". How can I allow a specific domain to be whitelisted and allowed through the MTA? There is only one domain I am trying to relay e-mails to (and that domain uses a totally different, independent and standalone mail server with IceWarp).

Not sure what to do. I did some Googling but I'm having a hard time finding relevant results. Most of the search results I get are about trying to receive mail -- but I am trying to send mail. mail.sisterwebsite.com = mail4.myhsphere.com. We use FluidHosting for the e-mail on sisterwebsite.com.
(Repeating question just in case)
How can I allow a specific domain to be whitelisted and allowed through the MTA?
