Hey,

I have no idea what the problem could be. Symptom is that i don't get 
emails. Even confirmation email from https://lists.systerserver.net did 
never arrive!

Oh, just got an email from immerda that explain things:

 >>>>>>>
Systerserver says:

$ dig +short TXT lists.systerserver.net
"v=spf1 mx a -all"
$ dig +short TXT systerserver.net
"v=spf1 mx a ip4:89.106.208.4 -all"

Which essentially says, "we only send emails from 89.106.208.4 and
everybody receiving emails from a different IP should block/reject/drop
these emails."

Since systerserver.net tries to send us emails over other IPs (IPv4 and
especially IPv6!) we are rejecting these emails.

They must fix their SPF entries.

And they should make sure to receive emails under postmaster@

postmaster at systerserver.net
host mx.tuxic.nl [46.23.85.85]
SMTP error from remote mail server after RCPT
TO:<postmaster at systerserver.net>:
550 5.1.1 <postmaster at systerserver.net>: Recipient address rejected:
User unknown in virtual mailbox table
<<<<<<<<<

Fixing SPF should do the trick.


cheers!
