After reading some of the other posts, I think maybe I miscommunicated my
problem, and maybe it's not quite like Neil's after all.

My probem is getting things from Mailman's qrunner into the sendmail queue
using the SMTPDirect module because sendmail takes up to 160 seconds per
name to reject names being fed to it from qrunner that it can't lookup.

[If it were a problem after it got to sendmail, I probably would have
chosen a sendmail specific forum to deal with it, so as not to drag this 
list off topic.]

Sorry for any confusion.
