Also, does my server need to have support for say cram-md5 if I am trying to authenticate to that isp? Even though I have the lines:
in my sendmail.mc file.

The only thing I get when I telnet to my own server is:
I dont have ANY of the AUTH protocols that SHOULD be in there. Could this be causing the problem?

Thanks,

Because if you followed this guide you set up that the client must first run STARTTLS and then authenticate. But when you STARTTSL, AUTH isn't AUTH anymore but It's 43feq4354tg45tX or something like that, "unreadable to human eyes", because it's encrypted.

Ok, so my server not having the AUTH option when telnetting into it is ok? And that wouldnt have anything to do with why I cant auth with my home ISP mail server?

Thanks,

Could you post an update to include how to setup sendmail with an ISP that requires SSL Authentication. I have ATT Yahoo DSL and their SMTP uses port 465 Secure Authentication and I'm not sure how I would modify what you have here to make it work. Thanks in advance for you help.

Hey all---
I was pointed to this how-to last year after getting verizon dsl. Great tutorial....worked first time....but my question is this:
I am the only one using the pc...it's here at the house. I use pine for mail. It shows my user name and I have to enter password. I'm ok with this but since I am the only one using the machince, can I set it so I don't have to enter my password and user name or can I have the password saved like username is and all I'd have to do is hit enter?
Thanks---
all the best

Well I am trying to set up on a slackware 11 server with SMTP_AUTH the problem I am running into is that openssl is not requesting the FQDN. I check saslaythd and got OK I did the telnet 25 bit and sendmail is showing STARTSSL and LOGIN Plain. But I can not relay any mail through the box. I get the did not issue MAIL/EXPN/VRFY/ETRN from a box that has been relaying though a Slack 10 box that has SMPT_AUTH set up the hard way. What am I missing?

Hello everyone,

I've followed this guide ages ago and got it working nicely, even played with it a little bit more, to got it working on two hosts and some other goodies.
But now I have a little problem at my companies SMTP server.
The server is located in Slovenia but we need to send some mails as user@xxx.ac.be (Belgium) for our client, which we can not, because all servers reject these mails. I don't know the exact reason why they are rejecting, because my boss didn't give me the root password yet so I could check it out.
But I think I know how to solve the problem. I think it would solve it if I would RELAY all mails that have host xxx.ac.be to our clients SMTP server in Belgium. I think I could do this with SMART_HOST, but the problem is if I add their SMTP server to SMART_HOST then ALL mails will be relayed over to them, which I do not want, I just want that mails with their hostname will get relayed over to their server and then sent further out. Is this doable? And how?
Thank you!

Kind regards,
Thomas

Hello,

What should i do, if i want to authenticate from the shadow files of sendmail virtual domains, which are created separately for each domain in /etc/vmail with the name "shadow.DomainName.com"?

I am not getting any help related to it.If anyone has any idea, please do suggest.Thank you.

You need saslauth daemon and run it with -a shadow parameter.

Then you need to create a /etc/mail/virtusertable and put in there like:
name-you-desire@domain.com username-from-shadow
Hash it the same way as explained in this how to
this will transfer mail for one name and domain to a specific username on the server.

And then comes the part which I don't understand perfectly, you need to create /etc/mail/generics-table and the format should be:
username-from-shadow name-you-desire@domain.com

This should restrict the user from sending out mail from a different domain or name, but for some reason it doesn't work.
You need to recompile sendmail with some flags I think, but I'll check that later, just a quick reply from work.

Hello

Thank you for the reply, but i think you didn't understand my question.I have virtual sendmail domains created by linuxconf.Each domain has its own passwd and shadow file created on the standard format.

Running "saslauthd -a shadow", makes authentication from the default shadow file for real users and not for the virtual mail domain users.

/etc/mail/virtusertable is used for mapping e-mail addresses to user names.I just want authentication to be carried out from the domain's own shadow file.Is there any implementation for virtual domains regarding SMTP Auth or they have any other alternate for it?

After setting up the client-side auth part in the LQ AUTH SMTP HowTo, follow the instructions found in this blogger post including AP's addendum in the comments. It basically shows how to use STunnel to establish SSL encrypted connections.

Hope this helps.

Thanks SiegeX,

That was a really good guide. Worked fine on FC9 and CentOS 4.7

With a few changes mostly on the m4 command to use the proper sendmail.mc file, this worked like a charm. Thank you for the fantastic HowTo.

It's just not happening for me, I have been mucking about with this for a week and I still get
reject=550 5.7.1 <postmaster@liftcapital.com.au>... Relaying denied. Proper authentication required.


so heres my thing

General FYI...

For Slackware 13, Sendmail.conf needs to be in /etc/sasl2
