explain whitelisting better #731

Does whitelisting also make mailcow ignore SPF?

What happens if i whitelist a To address?

My usecase:

I'm receiving mail via a mailforwarder. e.g. mail is sent to info@somedomain.com and is forwarded to info@mydomain.com.

The problem with this is that the SPF is mismatching for mails that are forwarded to me.

Will adding info@somedomain.com to the whitelist solve this? Or does that only whitelist From addresses and not To addresses?

Which kind of whitelist do you mean, Mailcow has multiple whitelists for different purposes (spam filter address whitelist, forwarding host server whitelist, etc.)? If you mean the spam filter address whitelist, that effectively just lowers the rspamd score by 1000 points, which should make up for the SPF failure penalty. Alternatively, consider adding the mail server of mydomain.com to your list of forwarding hosts.
