| Mail queued for days? Come on, this isn't FidoNet -- you're not going to have to make hundreds of call attempts to get that message to a popular BBS.
A message sitting in a queue for more than 90 minutes is just pointlessly idiotic. Bounce the message as undeliverable and give the sender the option to take a different approach.
I'm not for DNS redirection at all, but arguing that implementing an unwise DNS configuration breaks an unwise MTA configuration is recockulous. |

| The MTA standard is to return a warning after 4 or 5 hours.
And return a failure after 5 or 4 days.
I want the warning in 4 or 5 seconds. Without DNS redirection, you can get the warning in 4-5 seconds. |

2 edits | said by AstroBoy:The MTA standard is to return a warning after 4 or 5 hours. And return a failure after 5 or 4 days. Most MTAs (Qmail, Postfix, Exim, Sendmail) have a single variable: maximum queue lifetime. No messages are sent back to the originating email user until the queue lifetime is exceeded.

Of course, this really only presents an issue for home users running their own mail server that are also using their ISP's DNS service with redirection. As long as the gtld and other top level domain servers remain redirect free the Internet is in fine shape. |

What if the destination server suffers a two hour downtime? Should the message bounce immediately, or provide a warning immediately and deliver it two hours later when the server is back up? |

| said by Guspaz:What if the destination server suffers a two hour downtime? Mail server redundancy is a pretty basic commodity these days. This can encompass everything from basic backup MX capability to replicated filesystems with DNS-based failover. Even the free providers offer this level of redundancy. For the hobbyist there are offerings like »www.rollernet.us/ who will provide free backup MX service.
said by Guspaz:Should the message bounce immediately, or provide a warning immediately and deliver it two hours later when the server is back up? Boucing the message tends to provide the clearest result, as users tend to resend on any kind of warning anyway. |

Cortland, NY | most users are stupid can call their IT savvy friends. I'd like to see NDRs just fall into the black hole of a bit bucket. Then again, I am a jerk  |
