Hello Qmail community, I have some architecture questions: 1) qmail_smtpd send (via pipe) to qmail_queue in the following order: - email message - "F" (from string) - list if "T" (To) strings Is this true?? (In qmail_queue.main, I see where it is checking "syntax" for "F" and "T".) 2) I am looking at Pictures/PIC.rem2local. It describes flow from qmail_smtpd -> qmail_queue -> .... qmail-local. - It says that qmail_send checks domain, e.g. heaven.af.mil. Where is this in the code?? - It says in qmail-lspawn that we check whether "joe" has an acoount. Again where is this check???
