I have studied Slackware Linux Essentials and Running Linux, and I'm
stuck.

I have my 9.1 Slackware installation configured to start the sendmail
server at boot and ps -acux shows that send mail is running.

I have a solid broadband internet connection, and I can retrieve mail
from my ISP using fetchmail.

However, I can't send seem to SEND any email. I've tried sending
messages in nail, elm and mutt without success.

Both elm and mutt say "Mail sent!", but it doesn't get to my ISP
(because I can't retrieve it with fetchmail).

Can anyone tell me what I might be doing wrong?

Thanks and Best Regards,

Probably using an incomplete configuration ;-)
(OK, I know it's not absolutely helpul a remark)

Could you please first check these simple tests that will
help us to have an idea about the type of error you have:

as user:

$ mail -H

as root:

# mail -H
# sendmail -bp -v -Ac
# sendmail -bp -v
# sendmail -bv -f yourlocaluser root
# sendmail -bv -f yourvaliduser(a)yourvaliddomain addressee(a)aoutsidevaliddomain

post the integral results (for the 'mail -H' an excerpt will be enough
in case you have zillion bounces :-)

This could be any of a couple of different problems ...
(but, good that you tried several apps...)

I _suspect_ the problem is entirely with your ISP. Many ISP will
refuse to accept mail from "suspicious" sources - even from their
own network. This is particularly true of (US based) cable TV
companies which see themselves as entertainment providers and not
as communication providers. example: comcast.net <<spit!>>

Many mail servers will refuse to deliver mail from a server running
on a dynamic ip#, or from a mail server in a netblock where the ISP
prohibits running a mail server. example: comcast.net <<spit!>>

Many mail servers will refuse to deliver mail from a server for
which the given hostname does not match the reverse DNS of the
sender's ip#. example: craigslist.com.

A quick look shows me that your ip# does NOT have a 'good' reverse
DNS set up. (assuming your SMTP uses the same ip# as your NNTP).
This is not good.




Because sendmail says, 'Mail sent', we can assume that sendmail
was told by the recceiving server, your ISP, that the mail was
accepted. The receiving server may have tried to send a bounce
notice for you, but for any of the reasons above, it did not
reach you.

A quick test: send me email at the address in the From: above.
I'll bet two BOZO points i get it :*) My server will talk to
anyone. Use a Subject: "MAILSERVER TEST" to be sure i don't
miss it.

If the poroblem is the reverse DNS and if all his outbound mail is going to just one relay
and thats where its bouncing,
then NO mail will go out.
Thats what happens if for example you use AOL fot your ISP and try to sned mail via mutt, nail Outlook Express etc
If you use AOLs mail it works
I found that out cause I tried somethinmg "cute" with cygwin.

Good Luck
