My original post:
----------------------------------------------------------------
Atfer we switched our mailhost from SunOS 4.1.0 ( Sun 3/280 ) to
SunOS 4.1.3_U1 ( Sparc 10/51 ), if the destination is not a host
name, mailer ddn refuses to deliver the mail:
----- Transcript of session follows -----
421 Host physics.att.com not found for mailer ddn.
550 xxx@physics.att.com... Host unknown
But we still can deliver the mail through Sun 3/280:
Your mail to physics.att.com is undeliverable.
---------- diagnosis ----------
<<< 550 <xxx@physics.att.com>... User unknown
---------- unsent mail ----------
Both are using same NIS and DNS services and same sendmail config
file.
Is there any patch to fix this?
---------------------------------------------------------------
Well, I have got only help from <ted@ags.ga.erg.sri.com>, but it is
VERY HELPFUL!
It turns out, that first I need a sendmail patch ( 101665-02 ) for
SunOS 4.1.3_U1 and second, as Ted adviced to make sendmail link to
sendmail.mx. It WORKS now!
Many thanks to Ted Nolan!
