I'm at the office, and I'm trying to send an e-mail through my e-smith mail server at home. When I'm at home, I can send e-mails through with no problem on the same network (I'm NOT using e-smith as a gateway, so technically it should be the same as not being on the network). But when I try and send e-mails from work, I get "Server Response: '553 sorry, that domain isn't in my list of allowed rcpthosts"
I checked all the e-mail client settings, and they're correct.
First, why does the mail server care about domains being in its list of allowed hosts? and second, what could cause this?
Thanks,
Quade
