You could investigate that. For example, when submitting via the "/usr/sbin/sendmail" binary, there is a -f option that lets you override the sender (if your login account is allowed to do so (at least I think that used to be the case, not sure anymore)). Perhaps there's something that needs to be done differently with the sendmail library as well, to achieve the same effect. Are you parsing the email to extract the sender address and passing it as an argument to whatever sendmail library function does the sending? Or are you letting it work out the sender address for itself? If it's the latter, perhaps it's just using the address of the user account that is running the process. Note that I'm not familiar with python's sendmail library (I've only used smtplib), so this might be a red herring, but its webpage says it has an smtplib-compatible API, but that it invokes the sendmail binary. Apologies if this is irrelevant/unhelpful. cheers, raf
