Webmail + cloudflare and SMTP website

[a99]

Hello .

I just installed hestiacp on my aws server cloud and i use cloudflare. I use it as an smtp server sendinblue.
I can send emails from webmail, but I don’t receive emails back.

Spamhaus has gone mad

I haven’t got to the bottom of this yet, but thought I’d post about it in case anyone else is affected. A client running Hestia was complaining about not receiving mail.

However when I went to check at https://check.spamhaus.org/ its not listed. IP and all associated domain names are clear. I can’t figure out what’s going on. In the meantime, I’ve edited /etc/exim/dn…

To remove spamhaus from the “dns blocklist”

sed -i "/zen.spamhaus.org/d" /etc/exim4/dnsbl.conf
systemctl restart exim4
