    Hi,
    I have a client that uses MP (Version 2, the old one) since years without any problems. Suddenly he had a problem: His NL could not be sent anymore, he received these kind of answers in his inbox (3 examples see below) As far as I know, all or nearly all mails werde refused.

    WordPress ist on the newest version, it was checked for any malcode or viruses with wordfence. I could not see any problems. He told me, that he did not change anything within the configuration of MP.

    So my only idea is, that the senders adress might be corrupted. In that case I would suggest that he should chnge the senders adress. Does that make any sense to you or is the problem something else?

    Thank you!

    Here are somne mnessages he had in his inbox:

    Hi Raphael,

    Please note this is the support forums for MailPoet 3. We don’t support MailPoet 2 here.

    Based on your headers above, whichever sending method your client is using they have been blacklisted by Spam Haus, one of the main blacklists. They’ll need to get in touch with whoever handles the email sending and work with them on getting de-listed.

    Thanks!

    Thank you for the information. My client agrees to change from MP2 to MP3, so I will update manually. But there is another – very, very strange – problem:

    My client has a new computer. So he sent the NL from his new computer and it failed. All 150 mails were refused. Then he tried it from the old computer, here it worked. But if an emailadress ist considert to be a spamer adress or not, does not depend on the computer, that is used.

    So i will do the update and maybe in the meanwhile you can answer if you see any explantion for thet strage effect with the two computers.

    Thank you
    Raphael
