Thanks AdamGsm! I tried mxtoolbox and it says I'm on UCEPROTECT Level 2. Is that the same thing as Microsoft? My bounce says "550 5.7.1 Unfortunately, messages from [my ip] weren't sent." That sounds like Microsoft right?

How do I know if im blacklisted in the first place? My emails to my professor keep bouncing and I dont know why. Im on a student plan from contabo.com

Is there like a free tool I can use! Thanks everyone

In Poland we have PL-IX and they have standard peering agreement template, one page. Very simple. But for my small network I use email too.

Same tho. Centos 7 was my last holdout too

I had Contabo storage VPS in Singapore. 400GB promise, 400GB df -h showed. But network was 100mbit not 1gbit at peak. "Fair use," they said. Specs right, experience wrong. Different crime, same courthouse.

Same here, Hetzner replaced a backplane fan at 3am CET. Got email with photo of tech holding the old fan. Contabo took 11 days to tell me my NVMe was "being tested" and then they just wiped it and sent it back empty.

Never again.

My Contabo Ryzen 5600 box is still alive at 22 months but I monitor it like a sick patient. Smartctl shows 18K power-on hours, no reallocated sectors yet. I run it as a secondary backup target only, nothing production.

The real joke is their "server grade" marketing. I opened a ticket asking for BM...
