Crontab and email and hostname

[Coolmar]

Hi,

We recently moved a server over to new hardware. Everything is fine but we are noticing something strange. Whenever a cron job runs that emails the output...it has the name of the old server. I even ran a job from the cron to test it by sending myself an email and put mailx -s "Test from `hostname`" email@domain and the hostname was resolved correctly but the email still had the old server name in the "from" field in my inbox. So where does cron get the "send from" name from?

Thanks,
S

Check your DM line in your sendmail config and verify you are not masquerading

Hi,

probably from the user's description field in /etc/passwd

Hi:

Assuming that 'hostname' and/or 'uname' report the server name correctly, then look in '/etc/mail/sendmail.cf' for masquerading. See the 'DM' macro.

Hi,

It might be picking it up from the description field in /etc/passwd

Hope this helps,

uname and hostname report it correctly and the DM macro in sendmail.cf is blank....anything else I can check?

What does /etc/hosts have? What output does nslookup give when you lookup by ip address?

[Coolmar]

/etc/passwd was right. Thanks!
