Is that 1 cpu?
Nah, I went with 2vCPU

I think it depends on the workload. It does not have to do a lot, but at high volume it adds up
Too early to say because I haven’t migrated all my workload yet
I’ll update the thread when I connect the remaining MTAs with this proxy
Awesome. The smallest I have deployed on was 2cpu/4gb and it worked fine up to a million an hour. But that was not official testing.
In addition 2C 4G ,but only 700MB used. CPU only 10%
→ The amount sent per day is between 5 million -8 million per day. Memory and CPU usage ; For reference only .
Oh sweet
Good to know. Thank you.

I see occasional errors like these. I suppose they are normal?
What is IP_A PORT_B? I never found this error on my server.
Ip-a is my MTA I think
Ip-b is the Mx server’s address
Did you replace those values with placeholders? I don’t remember ever seeing an error like that
ahah yeah
I did
I literally asked ChatGPT to anonymize the IPs
