sendmail : modify "From:" field

[j773303]

/etc/hosts
10.1.12.1 hostA.123.com

When I use root to sendmail, "From:" filld would display "root@hostA.123.com" in the outlook express. I want ot "From:" only shows "root". Is it possible to do that in sendmail 8.9.3 ? Thanks.

[j773303]

Does anyone has the experience about how to let "FROM:" doesn't include "@hostname.domain"

Thanks in advanced.

Try this in /etc/mail/sendmail.cf

Rroot < @ $* > $* root.$w < @ $1 > $2 Special case for root

Hi Just try Dj parameter in your sendmail.cf

[Steven E. Protter]

Shalom,

1) The sendmail should be updated.
2) So long as the domain name desired is under 8 characters, you can change the system hostname to get the same results as the Dj directive host becomes host.your.net

Actually, what I gave you displays:

root.hostname@yourdomain.com

as long as the DM maacro is set...

# who I masquerade as (null for no masquerading) (see also $=M)
DMyourdomain.com

Rroot < @ $* > $* root.$w < @ $1 > $2 Special case for root

I can't set above line in the sendmail.cf due to the start sendmail daemon would got error message. Can you give a sample file "sendmail.cf" including above line for me testing. Thanks.

Error msg as below:

/# /sbin/init.d/sendmail start
/etc/mail/sendmail.cf: line 1642: invalid rewrite line "Rroot < @ * > * root.w < @ 1 > 2" (tab expected)

[Geoff Wild]

Yes - you need tabs...I'll attach that section.

Thanks. sendmail.cf is ok to start.

But I don't want to
"root.hostname@yourdomain.com" in the mail "From:" , I just whan "From:" shows "root" . Is it posslbe to do that ?
Thanks in advanced.

[Geoff Wild]

Sure - drop the .W$:

root < @ $1 > $2

[j773303]

Rroot < @ $* > $* root < @ $1 > $2 Special case for root

After changed to above, in the mail "FROM:" still show "root@hostanem.domain"

Could you check the format when I configure wrong ?

Is it possible only shows the username, such as "root", "user1", "user2" and so on. Thanks in advanced.
