Send email rejected by RBL to user spam folder

Hello, recently we have seen lot of emails being rejected because sender IP was in one of the RBL DNS list. Some of those emails are genuine but with shared hosting's with shared IP end being rejected. Is there a way that instead of email being rejected its sent to user spam folder. This will generate lot of spam but that's fine.

Thanks

Hello,

RBL does not allow it with default settings on Directadmin server.

You can add domains from your server to /etc/virtual/skip_rbl_domains for which you want RBL to allow all incoming emails.

Thanks for the quick reply, this is going to be tedious. I have few questions, is rejected email dropped or sent back to the sender. If its sent back with reason that would be nice, so atleast sender can fix the issue or find another way.

For skip_rbl_domains, whats the format. Same as esf_skip_hosts *.hostname.com and do we use the sender mail server or actual host in the email address.
Thanks for your time.

Check section for wildlsearch or nwildlsearch here https://www.exim.org/exim-html-current/doc/html/spec_html/ch-file_and_database_lookups.html

Exactly they are used to search through /etc/virtual/skip_rbl_domains

Rejected emails as far as I know are bounced back with an error.

And it seems you can use:

- /etc/virtual/skip_rbl_hosts
- /etc/virtual/skip_rbl_hosts_ip

to white-list senders hosts.
