550 not local host advantexmail.net, not a gateway

I'm getting this error code on all my emails when I try
to send my emails in groups. (I'm not spamming anyone--
these are people I'm friends with!)
They are all the same error code, except the part where
it says "advantexmail.net" corresponds with whichever isp
they are using.
Anyone know why it is doing this?

Your ISP is trying to thwart spammers by restricting relaying of 3rd party
mail through their servers. You can probably get around this by turning on
authentication to your outgoing server for the 3rd party account -- go to
the "Outgoing Server" tab for that account and you should see the settings
there.
