Hello, I am trying to figure out how to figure best, that an authenticated_id somehow fits to whatever sender is given in the envelop of a mail. What I find confusing about it is firstly AUTH Parameter in the MAIL command seems to possibly contain a different email address than given in the FROM. The example from the Exim Guide[1] on Page 287 is
MAIL FROM:<[EMAIL PROTECTED]> [EMAIL PROTECTED] If this is set by the sender of the mail and not added by exim, does exim somehow verify this? Secondly I am notquite sure how to deal with aliases... for example, several users may be allowed to respond for webmaster or for postmaster or root. If Id simply say a user may only use whatever email address is given in /etc/email-addresses that may be extremely limiting. Isn't it normal to check for this, somehow? If it is configured in default Debian (and therefore Ubuntu) configuration I must have missed in by now. The version I use is 4.63 out of Debian Etch with the matching config package. Thirdly I wonder wether it is possible or makes sense to somehow check From:-headers within the message body...
