activation email not delivered

[thinkpadx270]

Hello,

this forum does not deliver account activation emails because the forum's email server is in SPAM blacklists:

2023-04-29 13:50:22 H=s.wrqvtzvf.outbound-mail.sendgrid.net [149.72.126.143] X=TLS1.2:ECDHE-RSA-AES128-GCM-SHA256:128 CV=no F= rejected RCPT <**MY-EMAIL-HERE**>: DNSBL listed at bl.spamcop.net

As of today it is listed in 3 blacklists:
RATS Spam
SORBS
SPAMCOP

you could check it here: https://mxtoolbox.com/SuperTool.aspx?action=blacklist%3a149.72.126.143&run=toolpage


My particular email server refused to accept the message because I use the SPAMCOP blacklist, as you could see in the above log.

You should either contact sendgrid.net and tell them to clear their IP address(es) or switch to another email service provider.
