What are the contents of the new mails? It's going to be impossible to troubleshoot unless you know the source and contents of the emails.

You can use the mail program to look at them.

Something has changed, Google's mail servers would never accept an E-mail from your non-fqdn address:

and the last line " i have new mail in /var/mail/root " how to desable this, my mail sending doesnt work since i have this line ....

The email that you are receiving is caused by an error in the crontab settings or the script that cron is running for the MRTG.
That should fix the "You have New Mail" on your screen when you are logged in.

To debug the sending of emails, can you run the following while you try to send an email and post the output here?

Code: Select all

tail -f /var/log/maillog

[Expertise]

yes i remember use contrab -e in install of MRTG :

i don't remeber exactly, i think it's that,
" contrab -e */5 * * * * <mrtg-bin>/mrtg <path to mrtg-cfg>/mrtg.cfg \
--logging /var/log/mrtg.log "

and script for start mrtg and i create too a symbolic link with 'S'xxxscriptMRTG name:

Using the mail command will not work unless you specify a valid from address. You can use the -r flag - although some MTAs don't honor that.
