[MM3-users] Possibly more a Postfix question than a mailman one one but...

I want to limit the number of simultanous connections for one domain that I send email to. According ot what i've managed to find on-line, I need to put in a transport map in Postfix for that. But Mailman appears to already be using the transport map for routing incoming mail:

transport_maps = hash:/opt/mailman/mm/var/data/postfix_lmtp local_recipient_maps = proxy:unix:passwd.byname, $alias_maps, hash:/opt/mailman/mm/var/data/postfix_lmtp relay_domains = hash:/opt/mailman/mm/var/data/postfix_domains

Can i append or pre-pend another transport file in the transport_maps listing and put in the entry for this domain that's been bouncing people off my list because of too many simultaneous connections?
