How to contact buyer from China (he have some question) my outlook express sad this -
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was ‘email@example.com’. Subject ‘Re: [VideoHive] Message sent via your Envato Market profile from tg0729000208’, Account: ‘pop.t-com.hr’, Server: ‘mail.t-com.hr’, Protocol: SMTP, Server Response: ‘550 5.7.1 firstname.lastname@example.org: Recipient address rejected: Blocked because of spam/virus. Please contact email@example.com for more info.’, Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79
The simplest solution is to just copy the buyer address and try to email him from another email account, if you have one (like gmail, or yahoo, etc)
The 550 server error appears usually if the email client (Outlook Express) is not configured properly (outgoing server does not have SMTP authentication enabled). Are you able to send emails to other addresses from Outlook?
Another reason could be that the server (yours or the buyer’s, I am not sure from the error message) was marked as spam or the email contains some content marked as spam.
But, as mentioned in the start, just try to email the buyer from another email account The fastest and simplest method.
