I get an error message when I send an email.

Error message when sending email

Here you can find a list of error messages and solutions when sending emails:

552 5.2.0 automated process detected unsolicited content

Problem: The recipient has rejected your email because the recipient does not like the content of your email. The exact reason can be provided by the recipient’s provider.
Solution: Change your email text until you are able to send the email. Remove all hyperlinks.

Error message after filling in a contact form on another website (SPF)

Problem: You sent a request via the contact form of another website (e.g. an online shop) and shortly afterwards receive a non-delivery message such as «Mail delivery failed» or «SPF fail». Some forms send your request with your email address as the sender, but via the mail server of the other website. The recipient checks whether that server is allowed to send on behalf of your domain (SPF). It is not, so the message is rejected and the error message is sent back to you as the supposed sender. This check protects your domain from strangers sending emails in your name. There is nothing wrong with your mailbox.
Solution:

1. Write to the company directly from your email program, for example to the contact address in the website’s legal notice. This way works.
2. If you like, inform the operator of the website: their contact form should use an address of the website itself as the sender and enter your address only as the reply address (Reply-To). You can forward them the error message for this.
3. If a message sent directly from your email program is also rejected, send us the complete error message via a ticket.
