I need my mail! (desperate call for help with sendmail)
 

Hello everyone,

Well, as you can see, I have a problem with my sendmail. I have installed it and am able to send mail, but there's one catch to it: my e-mail address figures as "user@host.domain.com" instead of "user@domain.com". This prevents me from sending e-mail, as most of the servers check to see whether the "host.domain.com" is a valid domain - which is not. However, if they checked for "domain.com", that is a valid domain and well recognized.

I am trying to configure my sendmail to leave out the "host" part when constructing my e-mail address, so that it looks as "user@domain.com". Unfortunately I seem to be looking in all the wrong places, even though I have tried reading most FAQs related to sendmail - I still have no answer to my question.

At the moment, I am using "nail" for sending/reading e-mails which allows me to specify a "from" address, but I'd like to make this configuration in sendmail and mail client independent.

I am using a Linux From Scratch "distribution", I know where my files are, I know that I should change something in /etc/mail/sendmail.mc, but what is the option?

Thanks in advance, hope to get this working soon.

Just wanted to also mention that I do intend to read up on all the options of sendmail, but at the moment I have other priorities... The only thing I hope to fix is this problem, the rest I will probably be able to figure out by myself.

Try adding this to your sendmail.mc and then recreate your .cf file.:

define(`confDOMAIN_NAME', `domain.com')dnl

werid! i never had that problem! let us know how you get on!

:( Afraid that didn't work out... Sendmail manages to get the domain name from the system, that's not the problem, the problem is it reports my e-mails coming from user@hostname.domainname instead of what I want (user@domainname). That option just "forces" the domain name to "domain.com".

what does your local-host-names file and hosts files look like?

G

local-host-names: Kamona
(the same as my hostname)
hosts (i'm assuming we're talking about /etc/hosts) has:
127.0.0.1 localhost.localdomain localhost
192.168.0.3 Kamona.CyberPunksNation.org Kamona
81.57.99.95 Kamona.CyberPunksNation.org Kamona


Probably should have mentioned this as well, I've installed sendmail following these instructions: http://linuxfromscratch.mirror.ac.uk.../sendmail.html

Ok... after countless hours of reading and trying and... I found it.

I had to add these two lines to my sendmail.mc (do this after copying the general-linux.mc):

MASQUERADE_AS(`domain.com')dnl
FEATURE(masquerade_envelope)dnl

And... it worked!
