I have to admit I don't understand the mail features here. I use the straight mail forward to send to my ISP and all send mail is from my ISP not domain mail.
I am sure you have a POP account set up with your ouroborous.com domain, right? And you have done POPs like that with other domains? If you find one that works (settings etc) then it should work here. Frankly, the webmail offerings just seem too complex for me - log in with browser, then choose which webmail type, then log in for mail. I've never used a domain POP acct. for SMTP but I have forwards and aliases for many to receive email.
Just for fun, why not set the .txt file to send the email to YOUR ISP mail account? Or some other working email to test if it sends? I honestly think the hitch is in your present infinite@... email account and how it is accessed, not the cgiemail. Just a suggestion.
