Will other Kaspa nodes reject transactions with fees below the minimum?

Other nodes will reject low-fee transactions from their mempool, but they will still accept them if those transactions arrive inside a mined block. In Kaspa, each node maintains a mempool — a waiting room for unconfirmed transactions — and applies a minimum fee threshold to decide which transactions to hold. A transaction that falls below that threshold gets turned away from the mempool. However, once a miner includes that low-fee transaction in a block and broadcasts the block, other nodes accept the block (and the transaction inside it) without complaint. This matters for beginners because it means fee rules are a soft social agreement enforced at the mempool level, not a hard consensus rule that would cause a network split.
