[SMTP] Kan het bericht (E-mailgeadresseerde is niet geaccepteerd door de server.) niet verzenden

meerdere e-mails worden niet ontvangen en geeft deze error.

Hi Christine,
it seems that the message you are trying to send it being rejected by your mail server, because it refuses to accept the recipient’s email address - this can be because of invalid formatting or the address being blocked.
You need to remove the message from eM Client’s outbox to stop the errors.

If these should be valid email addresses, reach out to your email account provider for more details on why they are being rejected.
