qmail doesn't scale with DNSSEC

[Former user]

Hi,

I found out at a big price (mail not sent for 10 days) that the software you're using to handle the SMTP part, does not scale very well in the future and basically is crashing as soon as you enable DNSSEC on your domains ( or other domains ) and you chain it with some custom DNS Server.

See https://www.webfactory.de/blog/patch-qmail-in-ubuntu-to-avoid-cname-lookup-failed-temporarily-errors for more details on this error.

Any idea if you can provide a patched qmail and/or switch to something else more future-proof?

Thank you and best regards, Julian

Hello,

we are not using stock qmail and we have not experienced any problems with DNSSEC yet.

Nevertheless next major version of poste is using whole another and more flexible solution to delivery...
