Hi Wietse, Okay - I think I've worked out the answer to my second question if I use the sendmail command line, with the -N option.
> /usr/sbin/sendmail.postfix -f t...@dev.kamar.kiwi.nz -N 'success, delay, > failure' k...@kamar.nz < tmp Reading through documentation / mailing lists, it looks like this has to be requested per e-mail when using the sendmail command. Is there anything I can set in the 'main.cf' file to change the default 'delay,failure' to be 'success,delay,failure' ? thanks Kent. > On 2/06/2017, at 11:59 AM, Kent <k...@kamar.nz> wrote: > > Hi Wietse, > > Thanks - I'll stop trying to attempt to do it this way then. > The SMTP approach does have the advantage of realtime feedback on the 'rcpt > to:' being accepted and I can spread the load across multiple threads / > connections. > > > Next question: Is there a way to get a 'delivered' notification (ie. once > the e-mail has left Postfix and is now at the destination mail server - or at > least, the next mail server in the chain). > (or any status change for that matter) > > > thanks > > Kent. > > > > > > >> On 2/06/2017, at 11:50 AM, Wietse Venema <wie...@porcupine.org> wrote: >> >> Kent: >>> Hi All, >>> >>> I have a MongoDB with a set of e-mails that I want to send.
