The answers I received fell into two categories. First, get a decent
mailer. Second, make sure that the SUID bit is set on sendmail.
To address the second: It is. And sendmail is owned by root, and is on a
local filesystem (not nfs-mounted no-suid). And it is usually running
properly. When an ordinary user sends mail, it is delivered. It is just
when vacation runs that it does not. I was able to implement a temporary
workaround - make /var/spool/mqueue world writable. I'm not comfortable
with that as a long-term solution, but at least my users can get their mail
through now.
To address the first: Yes, I should. I do most of my computing on Unix
platforms (and use XEmacs and VM). However, most of my internet mail I do
on a PC, and just started using the highly acclaimed Outlook Express.
Unfortunately, when playing with it earlier, I told it to digitally sign my
messages. Apparently, this makes it use an experimental mime type,
application/x-pkcs7-mime, which most mailers do not understand. I hope that
this is more readable.
Thanks to Andy Walden, Tom Smith, Martin MOKREJS, Dr. Thomas P. Blinn, and
Anthony Talltree for their responses.
