FYI
New M7o version of yam miner is available. It supports more MMC pools, extra protocols and has many other enhancements.
yam M7o has better connection handling for NAT and firewall setups, support for special chars in usernames/passwords and better pool compatibility.
Native support for MMC P2Pool and MMC-specific stratum protocol in yam M7o reduces rejects, provides more backup connections and better miner uptime.
Note that MMC P2Pool support in yam M7o provided for testing purposes - features can be changed or added as P2Pool software will mature.
Support for gpools MMC mining pool has been removed from yam M7o default config.
