Cannot send mail - "533 sorry, that domain isn't in my allowed list of rcp hosts
Posted on 2007-12-01
I use my laptop at my office and at home, and send Outlook mails from it. I have seperate mail accounts for this, so that I use different SMTP servers. I've been sending mails like this for years. Anyway, tonight, suddenly, I couldn't do it. Everytime I try, the mail bounces back with the following error:
Could not deliver to the follow recipient...
'firstname.lastname@example.org' 01-12-2007 12:59
553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)
I've never come across this time of error before. Anyone know what to do?
