If you mean using https://www.ckdhr.com/ckd/qmail-103.patch, qmail-toaster already use it with named as qmail_qmailtoaster-big-dns.patch

It's a different patch, that one you are talking about basically what it does is to increase the maximum size of a lookup qmail do when sending and e-mail, and the patch I was refering is to basically trim the information of the lookup qmail needs, on the dns.c it's just one line that is changed from "any" to "cname".

That was the only way I was able to make it sending e-mails again to providers that have a lot of records

I did now, I don't know what to say, but I've only be able to fix my problem after doing the one I was saying, that change just that single line.

Same issue afecting 3 of my servers (2 x86_64 and the other i686) and after recompiling individually qmail with that patch for each server I was able to fix that error message.

Great - thanks!

Rebuilding it with that patch worked for me too. :)

This was the patch:

Hmm, i'm using Kloxo-MR update from 2 weeks back.
Now i did send a test email to sdfd@live.com:
Apr 12 18:01:43 mail send: delivery 2086: success: User_and_password_not_set,_continuing_without_authentication./<sdfsdf@live.com>_65.55.37.72_accepted_message./Remote_host_said:_250__<8482ed98446fe407e97d924e2c43b8d0@kloxomrdomain.com>_Queued_mail_for_delivery/

I received it right away. Did the issue appear recently?
Kloxo-MR!
