Allowing smtp access from the outside world

When I do 'telnet localhost 25', it works, but
'telnet burk 25'(burk is the machine's name), it
says:
Trying 192.168.0.2...
telnet: Unable to connect to remote host: Connection refused

HTTP/80 and SSH/22 works, it is only SMTP that
gives me problems.

How can I allow access from other computers?

I'd guess you're running sendmail on a relatively recent RedHat distribution.
Please read the sendmail FAQ first (from http://www.sendmail.org/).
Also, RH installation/configuration documents should provide the needed
information.

If these fall short, this has been discussed for numerous times in here
as well as in comp.mail.sendmail .

Is it blocked by your ISP? Many of them take a dim view of customers
running smtp servers, because of the potenial for abuse. Can you access it
over ssh or ssl, to get around the ISP?

easy, just edit your /etc/mail/sendmail.mc

go to the line that reads:

DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1,Name=MTA' )dnl


change the "127.0.0.1" to "0.0.0.0" and then save the file.

type "m4 /etc/mail/sendmail.mc < /etc/sendmail.cf

then type "service sendmail restart"


Then others can connect to you fine.

Use something other that RedHat's 'broken as designed'
version, or read their documentation describing what they
must think is a user-friendly configuraration interface to fix it.

Well a first start would be to check the sendmail config files,
With my Distro (SuSE) all the files are in /etc/mail
there is a file called access that says this

# Network IP-addresses have to end on octet boundary, e.g. 127.0.0
# The right hand side `<keyword or ### text>' could be one of
# the keywords
#
# OK (accept mails even if other rules would reject them)
# REJECT (reject mails even if other rules would accept them)
# RELAY (relay this domain, implicit OK within other rules)
# DISCARD (mail are discard)
#
# or an `###' RFC 821 compliant error code and some text, e.g.
#
# ERROR:"550 We don't accept mail from spammers"
#
# Examples:
#
#cyberspammer.com ERROR:"550 We don't accept mail from spammers"
#sendmail.org OK
#192.168 RELAY
#
#

you will probalby find that in this file it says
127.0.0.1 OK

this allows localhost - but if you are open to the internet do not allow all
to relay.

Then you need to run make in that directory to create the new database file
from the access file.
