Cant send emails to gmail

andi

Hello,
i have a problem, i cant send emails to gmail, after a reinstall (before it worked).

Now the email will be returned with the message:
host gmail-smtp-in.l.google.com[142.250.13.27] said:
550-5.7.1 [xx.xxx.xx.xxx] The IP you’re using to send mail is not
authorized to 550-5.7.1 send email directly to our servers. Please use the
SMTP relay at your 550-5.7.1 service provider instead. Learn more at 550
5.7.1 https://support.google.com/mail/?p=NotAuthorizedError

I can send mails to other services.
My IP is not blocked by spamhaus.

Thanks for your help

Hello,

As seen in the link you shared from google they’re blocking e.g. IPs from ISPs. We can’t help you here and it’s not a bug of mailcow
