I'm not worried about that. Most of the Majorodomo responses are intentially using sender adresses which are invalid (hence I find them). Sendly, more than 90% of my mail is now blocked by SORBS accoding to the logs.
I'm worried that the pop2 is exploited or that the local relay allowance is being exploited. I could never figure out how to limit the pop2 to local domains with TCP Wrappers.
