Sendmail and Relaying

Hessian Rider · 03-03-2003, 11:30 PM

I'm having a serious problem with sendmail and I haven't been able to solve it for quite some time:

We are running a mail server on one of our machines and so far mail can only be sent from our hosts or to our hosts.
A user using a machine that is not of our network can not send mail to other domains - only to our own.
I want to allow our users to be able to send their mail through our server from remote destinations ( say, their PCs at home).
For example I want bob to be able to send mail to hotmail.com for instance(not our domain, obviously

from his PC at home which is on dila-up with dynamic IP.
I figured that if i include him in the access file everything would be ok, but it's still not working.
My sendmail config is:

divert(-1)
include(`/usr/lib/sendmail-cf/m4/cf.m4')
OSTYPE(`linux')dnl
define(`confDEF_USER_ID',``8:12'')
define(`confPRIVACY_FLAGS', `authwarnings,needmailhelo,noexpn,novrfy')
define(`confTO_QUEUERETURN', `4d')
define(`confTO_QUEUEWARN', `4h')
define(`PROCMAIL_MAILER_PATH',`/usr/bin/procmail')
undefine(`UUCP_RELAY')
undefine(`BITNET_RELAY')
FEATURE(`redirect')
FEATURE(`always_add_domain')
FEATURE(`use_cw_file')
FEATURE(`local_procmail')
FEATURE(`nouucp')
FEATURE(`mailertable', `hash -o /etc/mail/mailertable')
FEATURE(`virtusertable', `hash -o /etc/mail/virtusertable')
FEATURE(`access_db', `hash -o /etc/mail/access')
FEATURE(rbl,`rbl.maps.vix.com',` Mail from $&{client_addr} rejected; see http://www.mail-abuse.org/rbl/')
FEATURE(rbl,`dul.maps.vix.com',`Mail from $&{client_addr} rejected; see http://www.mail-abuse.org/dul/')
FEATURE(rbl,`relays.mail-abuse.org',` Mail from $&{client_addr} rejected; see http://www.mail-abuse.org/rss/')
MAILER(`procmail')
MAILER(`smtp')

Thank you for any advice.

all i can think of is that you've not got the right info in your access file, probably /etc/mail/access, try posting it here. The access_db feature works fine for me, and everythign else looks ok.

Code:

# by default we allow relaying from localhost...
localhost.localdomain           RELAY
localhost                       RELAY
127.0.0.1                       RELAY
192.168.0.2                     RELAY
192.168.0.1                     RELAY

you've quite possibly just got them on ACCEPT, not RELAY. any error messages you could provide?

In order to allow realaying from any network I made my access
file account-based - e.g:
user@mydomain.com RELAY
user2@mydomain2.com RELAY

My whole access file is like this.

I believed this way users will be able to use my MTA from anywhere to anywhere.
It appears that sendmail checks the recipient and if it is not local (@mydomain.com, @mydomain2.com) it rejects it.
I have removed blacklist_recipients, as I thought this makes sendmail check the recipient but it still does the check.

the logs look like this:

Mar 4 06:30:25 mail sendmail[4597]: GAA04597: ruleset=check_rcpt, arg1=<st_gyoshev@hotmail.com>, relay=[217.18.244.156], reject=550 <st_gyoshev@hotmail.com>... Relaying denied
