Idézem/Quoting Ralph Corderoy <ra...@inputplus.co.uk>:
Hi Steffen,
Then problem on my side, i should add an MX entry for
lists.sdaoden.eu which points to lists.sdaoden.eu not sdaoden.eu.
My knowledge of DNS is a bit rusty.
Mine too.
$ dig +nocomment lists.sdaoden.eu. mx
...
lists.sdaoden.eu. 14312 IN CNAME sdaoden.eu.
sdaoden.eu. 14312 IN MX 10 sdaoden.eu.
sdaoden.eu. 14312 IN A 217.144.132.164
If not MX for foo.com exists then foo.com's port 25 is contacted
directly, so an MX for foo.com defined as foo.com seems unnecessary.
Excuse me, I object!
If you do internet mailing in the 21st century you *should* add an MX
record (and use SPF, DKIM and DMARC)
All the best!
