please don't confuse my response here to David Huybregts'. I began
this thread. in my case i read the manuals and asked specific
questions and received no responses. not even rtfm
to be clear: kmail gives the user two choices -- smtp OR sendmail.
(I don' t know what you do if you want to use smail or some other
mta.)
Now, all i want to do is send a one-way newsletter to about 500
people. I was told on this list the easiest way to suppress
recipients is to use alias. I read all I could on the topic and set
up some test aliases. I read this needed to work through
sendmail.
I tested with the smpt choice in kmail's settings and the test's
failed.
so I swithced the setting to sendmail, configured sendmail as best
i could (per my earlier letter on this thread) and tested. seemed
to work so I used sendmail for four days. EXCEPT certain addresses
did not receive mail. Those addresses seem to be aol and compuserve
addresses. Unfortunately I didn't receive any error messages,
mailer daemon messages or aol postmaster messages. so it apears the
mail was received but not delivered.
my guess would be some kind of aol anti-spam mechanism clicked in.
I realize how that sounds oxymoron-esque. ;-)
In any event, what i am trying to do is extremely basic -- send to
a distro list.
any help would be appreciated.
