Level 2 and Level 3 are not blocklists that are suitable for blocking on their own. They are punitive blocklists. They should only be used as part of a scoring system, such as SpamAssassin.
If your outbound mail is being blocked by some server just because your MTA is in one of those lists, it might be worth contacting the postmaster at the other end, and asking them either to drop those two lists, to use them only for spam-scoring, or to whitelist your MTA.
