A common cause of problems for Mailing lists is the presence or absence 
of an SPF record for custom domains. I can't see ROK's e-mail address 
from your reposts, but you can do a quick check by doing a DNS lookup.  
Here's mine for example:

→ dig ferd.ca ANY
...
;; ANSWER SECTION:
ferd.ca.                3599    IN      A       208.94.116.79
ferd.ca.                3599    IN      MX      5 ALT2.ASPMX.L.GOOGLE.COM.
ferd.ca.                3599    IN      MX      10 ASPMX5.GOOGLEMAIL.COM.
...
ferd.ca.                3599    IN      TXT     "v=spf1 include:_spf.google.com ~all"
ferd.ca.                3599    IN      SOA     ns.phx1.nearlyfreespeech.net. hostmaster.nearlyfreespeech.net. 1406273317 600 180 86400 180

The MX records indicate that I'm redirecting everything on gmail, but 
the critical one not to be seen as spam or a spoofed e-mail is the TXT 
record with the SPF entry in it.

Background info is at https://support.dnsimple.com/articles/spf-record/ 
or https://en.wikipedia.org/wiki/Sender_Policy_Framework
-- your mail provider should possibly be able to give a line about it so 
people can configure their stuff themselves. Google's page is at 
https://support.google.com/a/answer/33786?hl=en if you're using gmail.

There's a good chance that something like that could be to blame for 
missing/non-forwarded e-mails.

Fred.
