Hi gang, Here's a puzzler. I have an account on a webmail system that supports pop3 and smtp so that I can use the service "externally" (without logging onto their system with my browser). The trouble is, I have to configure my own sendmail program so it authenticates when handing mail off to the mail service's smtp. I have checked a number of docs and FAQ's without success so far, although I am pretty sure the info I am looking for is buried somewhere in the awesome sendmail documentation. Any shortcuts or examples anybody might have would be generously rewarded as well as appreciated.
