Does mailman send one message at a time, or all at once?

I'm considering getting this MailHop Outbound service, however one of the restrictions they have is in this FAQ:
http://www.dyndns.com/services/mailhop/faq.html#q114 Q: What is the maximum number of recipients in a message sent via MailHop Outbound? A: You may specify at most 100 recipients per message. If you need to send a message to more than 100 recipients, you will need to split it into blocks of 100 or less. This restriction is necessary to deter spammers.
I run a 'mailman v2.1.5' list for club events happening around town. I have around 150 people on the list. Will this work? Does mailman send out one message at a time, or will I be limited to this restriction above?

P.S. if anyone can suggest a way to get out of RBL hell, I am all ears. I run Gentoo and Exim 4.54 on my home cable modem. I'm getting increasingly frustrated with this RBL shit. Many ISPs (AOL, earthlink, etc.) are blocking mail from my domain simply because I happen to be on a Comcast (Seattle, WA) dynamic IP.

By default, Mailman will group recipients together into chunks
the size specified in your mm_cfg.py, or in Defaults.py (if you didn't put in anything in mm_cfg.py).
However, if you turn on personalization, then Mailman will send
out one message per person. Search the FAQ for "VERP" and "personalization" in order to learn more.

Use an outbound mail relay service, whereby you pay them money to
act as your relay. Route all outbound mail through them. Make sure they're clean and not spammer-friendly, otherwise you're back in the same RBL hell that you're in now.

So are you saying, I could tell mailman to group in chunks of say 50 and even though I have 150 people on the list, mailman would deliver 3 batches of 50 to cover them all? Thereby I can keep below my 100 / email limitation that this service provides me?

Is this different than http://www.dyndns.com/services/mailhop/outbound.html Or http://www.no-ip.com/services/managed_mail/inbound_port_25_unblock.html
Can you (or anyone) suggest one that "just works" with my setup (above)?
Thanks for the reply.

Just set
SMTP_MAX_RCPTS = 50
in mm_cfg.py. You may also need to set
SMTP_MAX_SESSIONS_PER_CONNECTION = 1
depending on how your smtp service counts the 50, i.e. 50 recipients in one transaction vs. 50 in one connection.
See the
##### # Delivery defaults #####
section in Defaults.py for more info.
