Subject: Re: SendMail tini 1.11 not working

Clayton,

This is an old problem that Peter and I subsequently resolved over a
week ago (June 17). It odd that it's taken nearly 9 days to reach the
list. If this is a common occurrence then it may go some way to explain
why some contributors to the list feel they are being ignored. I don't
think the delay was from Peter's mailbox since I received a copy of this
email the day it was posted.

Regards

Bob
