Yes, but that block is normally in a form of being marked as spam. This is different. Mail gets dropped without ever reaching the recipient's mailbox.
As an aside, I have been running my own mailserver for years and it's been working fine since the beginning. Getting marked as spam here and there, but for the most part - fine. I'll shift the mail setup at some point to have proper dkim support, but for now all I can say is - avoid gmail.
old man shouting at clouds
I understand how spam was a problem and why, at a glance, it seemed like a great idea to simply block any email that does not come from a previously known/trusted IP. However, in my opinion, all this has achieved are two things:Interesting. I don't really want to get into troubleshooting, but general curiosity has me wondering a few things since my server gets delivered to Gmail but only marked as spam for a new domain for the first couple weeks.
Is there a hard spf fail? Is your IP or domain on any blacklists? Is it a digital ocean or similar vps provider using their IP pool? Do you get any bounce back from Gmail with a reason or is it silently dropping?
Yes, it's digitalocean and yes, I get a bounced message telling me to use an email provider. I have some plans that involve a wider setup than just my lemmy instance, hence the delay in implementation.
Ah yea. I've seen the whole digital ocean IP space be blocked. They really dont like digital ocean.
