[Mailman-Users] RBL Management for new list/IP

This is not so much a technical question as advice seeking. My apologies 
if it isn't appropriate for this list.

I am new to mailing list management, though not new to mail server 
management. I've never run into this problem.

Background is that I am tasked with creating an announcement list for a 
group. I'm using a dedicated IPv4 which I have controlled for two months 
and not previously used for outgoing email. I have not idea what its 
prior "reputation" was. Mailman settings are pretty much default. I have 
proper SPF and rDNS records.

We have added just short of 1000 members, all by their request at the 
web interface. A few test messages went out about 4-5 days ago. Since 
then the only outgoing mails have been signup confirmations and messages 
to me as list owner.

Despite the relatively low volume, my IP keeps getting listed at 
Spamhaus CSS (https://www.spamhaus.org/css/). I can manually de-list it 
but it seems as though whenever we send out any mail we get re-listed. I 
have tried contacting them but gotten nowhere.

The only other RBL where we are listed is http://www.dnsblchile.org/. I 
put in a de-listing request with them over the weekend but they only 
work during the week.

Has anyone dealt with this, and if so, can you offer any ideas?
