Hi
Our box sends lots of notifications to users every day and today I've noticed
that all recipients from one specific domain (bluewin.ch) get stuck in the
queue. Here's an example:
E924E40406A4 2075 Thu Feb 13 19:25:50 no-re...@xxxxxxxxx.com
(delivery temporarily suspended: Host or domain name not found. Name service
error for name=bluewin.ch type=MX: Host not found, try again)
xxxxxxx...@bluewin.ch
However, I can do lookups with dig:
dig mx bluewin.ch
;; ANSWER SECTION:
bluewin.ch. 437 IN MX 42 mxzhh.bluewin.ch.
bluewin.ch. 437 IN MX 42 mxzhb.bluewin.ch.
bluewin.ch. 437 IN MX 10 mxbw.bluewin.ch.
dig mxbw.bluewin.ch
;; ANSWER SECTION:
mxbw.bluewin.ch. 3 IN A 195.186.99.50
Many other recipients work just fine. I'm not sure how to approach this issue,
any hint is greatly appreciated!
