In my Perl code, I was using Net::SMTP and MIME:Entity to send email through my Sendgrid account (from their v2 api, where I could use my account login as the api)...
it was working flawlessly.
But we moved servers to a newer version. Still Unix (Linux), but has newer hardware, including a newer version of Plesk. The IP addresses are all the same, we moved them to the new hardware. We did change the IP address that is the primary one, but we made sure we added it to sendgrid whitelabel...
So I'm clueless why it would stop working. I am not getting any errors in the code, the api is connecting. But I don't ever see any emails, no matter what I do.
Since no errors, not sure why it does not work.
Here is my code, do you see the flaw that would make it fail?

Anyhow, I have no idea why it is not working. The Server admins checked and there are no errors or no emails in the queue, either... so nothing just stuck somewhere, that we can find...
Can someone see anything, aside from my terrible programming??? lol
Thanks, -Richard
If the program worked before, did not change, and is not giving any errors, there is probably nothing wrong with it. Test sending the email manually.
Start by encoding your username and password:
Then use telnet with encoded username after the first 334 and password after the second:
