Sendmail saying "user unknown" after setting up MX
Hi Friends,
I set up the sendmail in my perosnal home lab. I am using mutt to send the email in between the machines. Everything is working fine if i send email like <username>@<hostname>. Now i set up the MX record for my domain "home.com" and then i was trying to send the email to like root@home.com, but in this case as soon as i press "Y" to send the email in mutt; i get this error
Even in the sendmail logs it shows user known. I know that my sendmail was not configured to accept message from the domain home.com, so i added the home.com to /etc/mail/local-host-names file but still this error remains. It is weird and i assume i should get a delivery failure with something saying like "relaying rejected"
So can anyone please help me figuring out what is going on here ?>

Hello,
I manage a large sendmail server that handles more than 20,000 pieces of mail per day. It's a bit unusual in that all this mail is only being sent to and from 4 local accounts. (It's an automated transaction processing system, whereby users submit a transaction via email attachment). ... (2 Replies)

gpgmailtunl
GPGMAILTUNL(1p) User Contributed Perl Documentation GPGMAILTUNL(1p)NAME
gpgmailtunl - Encrypts an email message into the body of another email.
SYNOPSIS
gpgmailtunl [options] --encrypt | --decrypt
DESCRIPTION
gpgmailtunl is a filter program that either encrypts an email message using the Gnu Privacy Guard and sends it to another recipient or
decrypt an email message and forwards unencrypted to another destination.
It can be used to exchange emails across an open network betweeen two trusted systems.
TYPICAL USAGE
This program is intended to run from program like procmail or sendmail to create an email tunnel between two systems. Of course this is
not as secure as using gpg as an end user program, it may be convenient in certain case.
ENCRYPTION
To encapsulates an email within another you pipe the message to gpgmailtunl.
OPTIONS
GetOptions( \%opt, "encrypt", "decrypt", "sign", "secret-file=s", "from=s", "to=s", "subject=s", "homedir=s", "local-user=s",
"recipient=s", )
or usage;
to This is the address to which the encrypted message will be sent. This is the only required fields.
recipient
This sets the keyid that will be used to encrypt the outgoing message. If unset, gpgmailtunl will try to find a key matching the to
option.
subject
Sets the subject of the outgoing message. This defaults to "Encrypted mail".
from
Sets the From header line of the outgoing message which will contains the encrypted one. sendmail will provides a default one if this
is not set.
sign
If this option is used, the outgoing message will be signed. In this case you should probably use to local-user and secret-file
options.
secret-file
File from which the secret to unlock the private used to sign the message can be read.
local-user
The keyid of the user that should sign the outgoing message. The default user will be used if not specified.
homedir
Sets an alternate gpg home directory. (This is where the keyrings are stored.)
DECRYPTION
To extract an email to be forwarded to the final user you pipe the encrypted email to gpgmailtunl using the decrypt switch.
Once decrypted, the encapsulated email message will be sent to the original destinator of the message.
OPTIONS
homedir
Sets an alternate gpg home directory. (This is where the keyrings are stored.)
secret-file
File from which the secret to unlock the private used to decrypt the message can be read.
