Can't send e-mail from Webmin

[akaRadar]

I'm new to Linux, so be kind
I'm running RedHat 8; Sendmail 8.12; Webmin 1.070.
I am able to send and receive e-mail to and from my client e-mail program thru my server using Sendmail just fine. The problem is from Webmin, if I go to Servers->Sendmail Configuration->Users Mailboxs, I can read any users mail (I'm the only user now), but after I compose a new email (from Webmin)and push the 'Send Mail' button it just sits there for several mins. and finally says mail sent, but it really never gets sent. Also the autoreply feature from the Mail Aliases never gets sent out. From my mail log I get several entries that look similar to this:

" ctladdr=archive (504/504), delay=04:30:07, xdelay=00:03:09, mailer=relay, pri=480165, relay=localhost.com. [10.11.12.13], dsn=4.0.0, stat=Deferred: Connection timed out with localhost.com."

This may or may not be related to my problem.
I have SMTP AUTH implemented if it matters. I am also on a static IP always on connection. I would be glad to give more info if needed. Thanks a lot!

Thanks, here is my current sendmail.cf

dnl This is the sendmail macro config file. If you make changes to this file,

-----------------

I'm a little worried about that 5th line from the bottom about accept unresolvable domains, should I comment that out? I'm pretty sure that's not my problem but I want to protect as much as possible from spam.

Also, today I got a notice thru the RedHat Network of a new Sendmail package and new Sendmail-cf. (Sendmail 8.12.8-1.80) If I install these will I lose any settings?

Thanks again,
Bill

*dnl define(`SMART_HOST',`smtp.your.provider')

'smtp.your.provider' should be filled in w/ valid information

Try inserting:

Dmbar.com
define(`confDOMAIN_NAME', `$w.$m')dnl

where 'bar.com' ='s your domain information 'if any'

*I want to protect as much as possible from spam.
commenting that line out won't make a difference.

* If I install these will I lose any settings?
It is very possible. I would recommend that you backup your active *.mc file, save it to your home dir.. a floppy, anything to ensure it's not lost.. when you upgrade your sendmail (which is always a good idea) you can use your *master.mc file to re-build your cf.. *yes it will/should over write your existing settings.&quot;

Thanks again for the reply. I tried what you described (the best I know how), but had no luck. Like I said, I'm new at this so I'm sure I am overlooking something. I have not done the update yet. May try that this weekend.

Thanks, Bill

I have the exact same problem.

What is happening is that sendmail is trying to resolve to 10.11.12.13 the i.p. number for a registered domain localhost.com

If you look at your /var/log/mail file you should see a line similar to this.

xdelay=00:03:09, mailer=relay, pri=120222, relay=localhost.com. [10.11.12.13], dsn=4.0.0, stat=Deferred: Connection timed out with localhost.com.

Now that being said. I know what the problem is but I have absolutely no idea how to fix it.

I reinstalled sendmail, no luck.

I'll be working on this for the rest of the week. If anyone has any insights please let me know.

Thanks.

Make sure your domain name is in the relay_domains file.

Make sure you have the following in your acess file
localhost RELAY
127.0.0.1 RELAY
yourdomain.com RELAY

Make sure your domain name is inclded in local-host-names
yourdomain.com
mail.yourdomain.com
