bought a domen name+instapage+all stuff needed some time ago.
finally I got a time to work on it, and sticked with an issue – noone can’t send a message on site’s email while I can send it to anyone from site e-mail itself.
that’s what a return message from people’s e-mails says:
ACCNAME@SITENAME.info: host smtp.secureserver.net[216.69.186.201] said: 550
#5.1.0 Address rejected ACCNAME@SITENAME.info (in reply to RCPT TO command)
