Mail rejected by Protonmail

Forked from https://forum.cloudron.io/topic/9030/cloudron-spf-record-does-not-permit-ip/36

Just wanted to weigh in and mention that I'm experiencing the same issue - my scanner tries to send mail via the Cloudron mail server, it shows up with my home ip in the logs and mentions a SoftFail, and gets entirely rejected by ProtonMail.
When I send the same mail to a mailbox on the Cloudron instance, it arrives. And it also arrives when sending "manually" from the Roundcube webmail.

Any help would be greatly appreciated as I'm a bit lost here. I can also provide logs and headers.

@lukasgabriel I didn't yet check, but I think that has been resolved with Cloudron 7.5

Reference -> https://forum.cloudron.io/post/69583

Update: I can confirm that the ip leak has been fixed with 7.5. Just tested successfully.

@Kubernetes Alright, thanks! Going from the last update entry in my Notifications tab, I think I am on version 7.4.3 - not sure how to definitely check that. But that would explain the problem!
Found the version in the settings tab & will update!

Some more info: When I add my home IP to my SPF record, it does no longer SoftFail, but it still doesn't arrive in my ProtonMail inbox. I'll keep trying

@lukasgabriel You may check that you are not on ubuntu 18! i remember there was something about that latest node version and ubuntu 18 doesn't work together, so update to 7.5 may fail.

@Kubernetes Thanks for the heads up! I was on Ubuntu 20.04
The update did indeed fix the SPF issue.
I'm still struggling with getting the mail delivered - paradoxically not even automatic forwarding works, but manual forwarding does... - but I don't think that is related to this issue.

@lukasgabriel So, there is no bounce and mail does not end up in spam ? It just disappears? You can see the mail event log to see what protonmail is responding with - https://docs.cloudron.io/email/#event-log

Also, have you tried https://www.mail-tester.com/ already for any other errors?
