But a laptop that’s sometimes inside, sometimes outside doesn’t have a fixed port to connect to. For those cases, I’d like the dovecot server to recognize the outside ports on the inside.
Well, if offering the *exact same* functionality on a second port is all that needs to be done, having the server's host firewall (iptables?) duplicate the NAT on your border firewall for internal accesses should do just fine; no need to majick it into the dovecot config (which opens the possibility of functional differences being introduced unintentionally).
Assuming Red Hat or similar with no conflicting iptables rules (yet),
# iptables -t nat -A PREROUTING -p tcp --dport 30xxx -j DNAT --to :143 # iptables -t nat -A PREROUTING -p tcp --dport 30yyy -j DNAT --to :993 # service iptables save
