modification of field FROM

Hello Everybody,

I would be very gratefully if anyone could help me why the field FROM
is changed in our mail, when we send a non local mail.
This means:

When I do:

sebs059.bar.ses.alcatel.es ddts> mailx -s 'prova'
maria.freixes_graells@xxxxxxxxxx
..
EOT

In the syslog appears:

May 8 18:15:44 sebs059.bar.ses.alcatel.es sendmail[24361]: [ID 801593
mail.info
] k48GFiok024361: from=ddts, size=71, class=0, nrcpts=1,

[155.132.180.117], dsn=2.0.0, stat=Sent (k48FtW6P031781 Message
accepted for de
livery)


I would like to see in the following in the field from:
from=ddts@xxxxxxxxxxxxxxxxxxxxxxxxxx, is it possible?

Really thanks!!

I send our sendmail.cf:
