mail comes back to root?

**Lakshmipathi** · 08-30-2007

Hi,
when i sent a mail

mail -iInv -s hi lakshmipathi.g@gmail.com
>Mesg

the mail is not delivered at gmail instead it appears in /var/spool/mail/root

Why so?Help me.
Thanks.

This mail you see in /var/spool/mail/root, is it the same message you sent or is it a failure message forwarded to root ?

**Lakshmipathi** · 08-31-2007

no It's not a failure message ...the same message which i sent to my gmail id.
I think It's gets some how redirected to my root itself..any idea why this happens?

Don't remember the postfix configuration files at the moment.

Check the contents of /etc/postfix/canonical for any canonical redirections.

I don't use Fedora, so I cannot give you Fedora specific instructions. Run the postfix daemon in verbose mode (-v switch) and check your postfix logs. You surely can find a clue that will lead you to the cause of redirection.

If you're using smtpd, you can edit the file /etc/postfix/master.cf and locate the line that starts with smtp. Append -vv to the line (after the word smtpd to be precise). This will make smtpd ouput verbose messages to the log. You can increase the number of 'v's to increase the verbosity.

unfortunely i'm running sendmail on FC4 and not postfix

**pavlo_7** · 08-31-2007

Check if sendmail service is started. It needs to be running.

[/code]

Any clues?
I'm with this stuff for a week now ....

**Lakshmipathi** · 08-31-2007

Just now i noticed ,
have close look at /var/spool/mail/root
Its says something like,
----- The following addresses had permanent fatal errors -----
lakshmipathi.g@gmail.com
(reason: 553 5.5.4 <root@localhost.localdomain>... Real domain name required for sender address)
(expanded from: lakshmipathi.g@gmail.com

what's this mean????????????

**pavlo_7** · 08-31-2007

Not sure what that permanent error means. I guess it sends the mail to root if it cannot send it to the original address after certain period of time. I remember I had problems sending mail from FC4, but then I found that sendmail was stopped. I had to start it manually.

Code:

/sbin/service sendmail status

and if it says:

Code:

sendmail is stopped

start it:

Code:

/sbin/service sendmail start

then try to send it this way:

Code:

echo "testing mail" | mail -s "test" lakshmipathi.g@gmail.com

**Lakshmipathi** · 08-31-2007

hi,
i checked the status but it says,
sendmail running
