Configure Zimbra to warn about delayed delivery?

[thunder04]

Hey All,

We've had a few instances where people have sent time sensitive e-mails out to people and typoed on the recipient's domain name. The user has no idea their mail isn't being delivered until the message expires and our server bounces it. Is there a way to configure Zimbra so that it warns users that a message they're trying to send is delayed for whatever reason?

Any/all input is greatly appreciated.

Thanks!!

Emails are not guaranteed delivery and should not be used for time sensitive content

Is this another one of those config changes that won't carry over when we upgrade? We're currently using 5.0.7 and I want to update to the latest release over the holiday. I'll add it to my notes if so.

I know...I know...

Or it could be added I think to /opt/zimbra/conf/main.cf.in.

Read the bug report.

Before setting it through perform a

su - zimbra
zmlocalconfig | grep -i postfix_config_key

just to ensure nothing is overwritten when you make the change.

Alright, I feel rather dumb...

I don't want to mess anything up. How do I add delay_warning_time=4h to postfix_config_key. Will the following do that (as per the bug report)?

$ postconf -e delay_warning_time=4h
$ postfix stop
$ postfix start

According to the grep search, "postfix_config_key" is currently empty.

Yes, that's exactly it.
