This is why gmail changes the message and instead use "[email protected]" as envelope makes "[email protected]" Since dbmail makes the forwarding and is the only instance who is knowing to 100% at this time that it is a forwarding, including to know both sides of the forward i would say this is the right place for envelope-rewrite because i have no idea with which rukes postfix could do this afterwards X-Barracuda-Envelope-From: [email protected] X-Barracuda-Apparent-Source-IP: 209.85.216.46 Received-SPF: pass (barracuda.thelounge.net: domain of gmail.com designates 209.85.216.46 as permitted sender) client-ip=209.85.216.46; envelope-from=reindl.harald+caf_=h.reindl=thelounge....@gmail.com; Am 10.01.2011 04:58, schrieb tabris: > On 1/9/11 7:43 PM, Reindl Harald wrote: >> Am 10.01.2011 04:37, schrieb tabris: >> >>> On 1/9/11 7:33 PM, Reindl Harald wrote: >>>> Does dbmail anything like gmail by forwarding messages >>>> i have not seen - seems to be straight forwarding >>> Strange question, DBmail is not an MTA. >>> What you ask seems to be a responsibility for your MTA (postfix, exim, >>> sendmail, etc). >> Hm not really >> >> * MTA receives a message and delivers over lmtp >> * dbmail looks in alias-table and see the forward >> * dbmail generates a new message and gives it to the mta >> * the mta does not and should not touch this message >> >> It happens the same as with my autoreply below (to you *g*) >> >> * psotfix/pickup will fetch the message from dbmail >> * uid=493 is dbmail on fedora/redhat >> > > I still think I do not understand the question... perhaps b/c you are > not showing what it looks like when I send you an email to your > @thelounge.net, and it is fwded to gmail.
