Hi All,
I keep getting this error message after trying to send emails to a gmail account. Does anyone know a fix for this?? Its becoming very difficult to use my email now.
SMTP error from remote mail server after end of data:
host gmail-smtp-in.l.google.com [2a00:1450:400c:c0a::1a]:
550-5.7.26 This mail is unauthenticated, which poses a security risk to
the
550-5.7.26 sender and Gmail users, and has been blocked. The sender must
550-5.7.26 authenticate with at least one of SPF or DKIM. For this
message,
550-5.7.26 DKIM checks did not pass and SPF check for [adelan.co.uk] did
not
550-5.7.26 pass with ip: [2001:41c9:1:423::231]. The sender should visit
550-5.7.26 https://support.google.com/mail/answer/81126#authentication
for
550 5.7.26 instructions on setting up authentication.
