[Gabriel Nava Vazquez]

Hi

i installed sendmail.8.8.7 in my linux/indy box and when i try to
send some message, i got the error:

hash map "Alias0": unsafe map file /etc/aliases: No such file
hash map "junk": unsafe map file /etc/mail/deny: No such file    

but the files does exist

what can i do? 
is this the reason pine crashes before send a message?

thanks

With recent versions of sendmail, you can do this via access_db, e.g.

	To:@hotmail.com		REJECT
	To:@yahoo.com		REJECT

See the cf/README file for details.

Sendmail

[Scott Taylor]

Hello all,

I'm digging through this O'Reilly Sendmail tome and it's making me 
dizzy.  Anyone know how to make sendmail allow outgoing mail from 
192.168.1.xxx local network?  (I get Relay not allowed errors)

Thanks.

Scott.

This is typically controlled by the file /etc/mail/relay-domains,
although the name and location is configurable via
define(`confCR_FILE', ...). Look for a line beginning with "FR" in
sendmail.cf for the precise pathname.

The file should contain a list of IP addresses and/or domains.
Relaying is allowed if either the source IP address or the destination
domain match an entry in that file.

Unless FEATURE(relay_hosts_only) was used, you can specify partial IP
addresses (e.g. 192.168.1) or domains (e.g. foo.com) to allow a single
rule to match multiple hosts.

When I recently had to persuade sendmail to
masquerade all the local hosts onto one domain
name, I ended up at

http://www.sendmail.org/m4/features.html

where there is actually a list of *all* the things
you can put in the FEATURE m4 macro. Some of the
things I needed were newer than the seventeen
pound book.

Good point.  So I'm guessing what I need is
relay_hosts_only
and just put: "192.168.1 RELAY" into the access file?
Anything else I should know?

This whole thing isn't making a lot of sense, guess I should have stuck 
with Procmail. =P

Note that all of this information is in the cf/README file, from the
sendmail source distribution. For pre-compiled packages, it is
normally included in the same package as all of the m4 files (e.g. 
"sendmail-cf").

Actually, you don't want FEATURE(relay_hosts_only), as that would
require you to list each IP address individually.

If you want to use the access database, you need to use
FEATURE(access_db); OTOH, the relay-domains file doesn't require any
specific feature.

Even if I did want FEATURE(relay_hosts_only), I still don't have a clue 
what to do with it.

You are making about as much sense as the book and the README.cf file.  I 
guess I'm looking for a step-by-step for something that should be quite 
simple, a how-to maybe.  Probably I'm just confused over the billion things 
that I read in this book and README file, none of which are speaking the 
same language anymore.

Hmmmm. I see you are right.

Life would have been simpler if I had found it
there.

This list (or someone on pine-info) told me one of
the features I needed. It didn't seem to change
anything. Eventually, a google search for the
things I knew led me to the related things that I
still needed on the sendmail.org site. I think it
was a combination of three sendmail features I had
to turn on together.

I guess I owe the lists a report on what was
needed. The information is home. So, later.

Fairly simple actually.

In /etc/mail/access make this entry:

The m4 stuff is only relevant if you need to create a new sendmail.cf
file. However, if you are using a typical vendor-supplied sendmail
package, then you probably don't need to.

Look in sendmail.cf for a line which begins with "FR", e.g.

	# Hosts for which relaying is permitted ($=R)
	FR-o /etc/mail/relay-domains

Assuming that line is present, simply add the IP address (or just the
network part, e.g. 192.168.1) to the file which is listed on that line
(in the above case, /etc/mail/relay-domains), then restart the
sendmail daemon.

If you modify any of the files which have an associated .db file, you
have to force the .db file to be rebuilt. You can do this manually
with "makemap", although vendor-supplied sendmail packages typically
do this whenever sendmail is started via the init.d script (e.g. with
"/etc/rc.d/init.d/sendmail restart").

If you modify a class file (a file which is referenced by an "F"
directive in sendmail.cf), you have to restart sendmail.

If you modify a keyed map (a file which is referenced by a "K"
directive), the changes will automatically take effect once the actual
.db file is updated.

Finally an answer that makes sense. :)

However, that was the first thing I did, but it didn't seem to work.  Even 
after I SIGHUP sendmail.

Something to do for access.db like newaliases does for alias table?

Hmmm.... Sendmail, if it's built correctly (Yeah, right!) should rebuild 
the db file for you.  If it's not built correctly, you have to figure 
out which hash program is expected and run it by hand.  The _may_ be a 
makefile for doing it too.

sendmail itself doesn't attempt to rebuild keyed maps; however, it's
common for distribution vendors to do this in the
/etc/rc.d/init.d/sendmail script and/or provide a Makefile.

That's OK Glynn,

Some of us have no problem and stay out of it when we don't know what the 
answer is.  Others top post, send attachments, request return receipts and 
blame 30 year old software vendors for not building it right.  Thus, making 
it easy for us to tell which people to ignore answers from. ;0)

Thanks for all the good answers.

Scott.

sendmail

[Veggies Unite!]

I hope that this is the correct place to e-mail this question - if
not, I would appreciate being re-directed. I've set up SuSe 8.0 on a
computer running through a router and a cable modem.  I have a
static IP, and I have a domain name pointing to the IP via a
Registrar that also handles a POP3 account. I've set up Majordomo on
my computer and would like to configure sendmail as a mail server so
that it will handle mailing lists aliases for Majordomo.  Also, I
would need to run a POP server to allow me to receive mail from my
server instead of the Registar.

In order for the aliases for majordomo to work, do I have cancel my
mail coming from the POP3 account via the Registrar?

Please let me know of any documentation on this or if you have
specific advice on what I would need to do.

Thanks,
Yvette

Re: sendmail

[Ray Olszewski]

I don't know that this is the best place to ask these questions, but it is 
at least a plausible place to start. I doubt any of what you need to know 
is SuSE specific. I'm afraid I do need a bit of clarification from you to 
be able to give you good answers. Details below.

You understand, I trust, that the router will have to be set up to forward 
port 25 (SMTP) to the server. Linux routers do this easily, as do all the 
other NATing routers I've looked at in recent times. The details will 
depend on what router you have, of course.

>I have a
>static IP, and I have a domain name pointing to the IP via a
>Registrar that also handles a POP3 account.

The omitted detail here is the relationship of the POP3 account to the 
domain name. Specifially, if the comain is whosis.com, does mail to 
anyone@whosis.com get redirected (by way of an MX DNS entry, for example) 
to the Registrar's server (and thence to the POP3 account)? Or is the 
POP3account in the form of someuserid@someotherdomainname.com ? The first 
setup will interfere with incoming mail but the second will not.

>I've set up Majordomo on

Aside from the details I've mentioned -- port forwarding and a possible 
MX-record conflict -- the sendmail part of this is a standard sendmail 
configuration. I'd expect SuSE to have an out-of-the-box setup procedure 
that handles this. If it doesn't ... what setup options does it give you?

>Also, I
>would need to run a POP server to allow me to receive mail from my

Receive it where? Do you have one or more workstations independent of the 
server? If so, this too is standard ... just install any of the popular 
POP3 servers (I run popa3d on my Debian server; there are several choices, 
and SuSE may favor one of the others). Then have the clients look to the 
LAN address of the server (assuming they are on the same LAN). If you want 
to get mail fro the server to off-LAN clients, the setup is a bit more 
involved ... post a followup if that's what you meant.

>In order for the aliases for majordomo to work, do I have cancel my
>mail coming from the POP3 account via the Registrar?

I can't give you an answer here until you explain how the POP3 account 
relates to the domain name. If e-mail to either majordomo@whosis.com and to 
eachlisname@whosis.com does NOT get redirected to the POP3 account, then it 
should have no effect on the server's operation. If it does get redirected, 
then it migh still work, if you have the server collect the POP3 mail and 
use a glue program like procmail to distribute it to majordomo itself and 
to the various majordomo lists.

>Please let me know of any documentation on this or if you have
>specific advice on what I would need to do.

The packages you need to use themselves all come with the usual kinds of 
documentation (man pages, Info files, other odds and ends, and often their 
own Web sites), and if you are not familiar with the range of HowTos and 
similar resources at (for example) www.tldp.org, you shouuld make their 
acquaintance. Aside from that, the better approach is for you to describe 
particular problems you need help in solving.
