Did you miss this: Postfix can also be configured to send mail when there is a delay: http://www.postfix.org/postconf.5.html#delay_warning_time I set mine to 15 minutes (15m) - that way a user will know that their message was not delivered when they sent it, and can follow it up with a phone call if it is important... EMail is reliable enough these days that we rarely ever get a delay warning... -- Best regards, Charles

A bit too soon, given typical grey-listing minimum retry timers. I would not send delay notices sooner than an hour after a message has been queued. FWIW, I use a 2 hour delay warning. -- Viktor.

We relay all outbound mail through our outsourced anti-spam provider (Webroot SaaS). So, unless *their* system is down - which it pretty much never is - our mail is accepted immediately. I've commented my config so if I ever fire webroot, I'll be sure to change it to 2 hours... Thanks Victor... -- Best regards, Charles

I did indeed miss that part, thanks! Actually, now that I've looked we don't have that configured. I find that = quite odd. I didn't set this system up, but they guy who did I have high r= espect for and I'm a little amazed that he didn't configure it. I'll do so immediately - thanks again for pointing this out! -Rem -----Original Message----- From: Charles Marcus [mailto:CMarcus(a)Media-Brokers.com]=20 Sent: Wednesday, September 02, 2009 11:04 AM To: Remy Lambert Cc: 'Postfix users' Subject: Re: Deferred queue settings?
