Conference turris::digital_unix

I am working on this call with Johan.(Author of this note)
This morning, when I was doing some test more, I saw that difference :

We have two system :  as2100 with OSF3.2e/1 ->>> UPPERCASE aliases works ok
                      astation 200   4.0b   ->>> UPPERCASE aliases doesn't
work

In the /var/adm/sendmail/sendmail.cf from first, I saw the following :

############################################################
############################################################
#####
#####           Local, POP and Program mailers
#####
############################################################
############################################################

Mlocal, P=/bin/mail, F=lsDFMmn, S=10, R=20, A=mail -r $f -d $u
Mprog,  P=/bin/sh,   F=lsDFM,   S=10, R=20, A=sh -c $u
Mpop,   P=/usr/lib/mh/spop, F=nsmFDM, S=10, R=20, A=pop $u


For the second (where I get problem)

############################################################
############################################################
#####
#####           Local, POP and Program mailers
#####
############################################################
############################################################
#
#                             +------ TAKE A LOOK TO THIS FLAG 
#                             v  
Mlocal, P=/bin/mail, F=lsDFMmnu, S=10, R=20, A=mail -r $f -d $u
Mprog,  P=/bin/sh,   F=lsDFM,   S=10, R=20, A=sh -c $u
Mpop,   P=/usr/lib/mh/spop, F=nsmFDM, S=10, R=20, A=pop $u


If you check, you can see that for local on the second sendmail.cf,
an u . 

If I remove these falg, my aliases in UPPERCASE work without problem
If I edit these file and put the u flag, after a sendmail stop/start, that
  doesn't work anymore.
If I remove these falg once more  after a sendmail stop/start, that WORKS 


 ??? !!! ??? !!! ???




WHAT IS THE REASON and the USAGE FOR THIS FLAG ??? 
I checked on a 4.0 system and the u flag
is turned on.


Hope that may give us more reply ...

Hi,

I checked on different osf 
                   3.2d  -> flag u is %%% NOT %%% used in sendmail.cf
                   3.2e  -> flag u is %%% NOT %%% used in sendmail.cf
                   3.2g  -> flag u is used in sendmail.cf
                   4.0   -> flag u is used in sendmail.cf
                   4.0b  -> flag u is used in sendmail.cf

Now I am asking me some questions :
 
1- Why was the u flag in sendmail.cf after release 3.2e

2- The u flag was maybe in sendmail.cf and removed on these two system (3.2d
3.2e)

3- That is the signification of these flag.. Usefull or not ?

4- I checked in the man pages of the sendmail in FLAG OPTIONS but
   cannot find anything for the u flag... Where may I found documentation for
   this u flag ... ???

In the 3.2e/1 system,

    The "u" mailer flag means "preserve upper case in names". Without it,
    all names will be normalized to lowercase for that mailer.
    
    Why the default was changed, I don't know, but it's a site-dependent
    policy. With the "u" flag the case of the name must match exactly, but
    there is less danger of mail for user "Jones" going to user "jones" by
    mistake (not that it's a good idea to have that situation).

Thanks for info but I haven't found any informations on that.

Customer is claiming problems whith YP's aliases ... 

When a yp-client send a mail to one yp-aliases adress exported in the
yp-aliase
database,he receive .... User unknow ....

Customer made soft link between /var/adm/sendmail/aliases (and .dir .pag)
tp /etc/yp/src.

I suggested to make a copy in place of link but ... 
 
On a system not in YP, mail deviverd without problems ...

From yp-clients, if customer use adress ALIASE@YP-server, mail deviverd ....
                 if customer use adress ALIASE, customer receive User unknow
...

yp-client site, if i do an ypcat aliases, customer find the aliase name
but cannot send mail from yp-cilent to these aliase. in /etc/svc.conf,
customer see aliases=local,yp ....

yesterday, that works fine. I cannot imagine what customer done between
yesterday
nigth and now but he tryed to export /var/spool/mail because he want that all
of 
the user may read mailing from all of the yp-clients...

these customer like to change somethings from rigth to left and from left to 
rigth
and after is claiming that doesn't work anymore ....

Any other ideas why ... ????

Have a nice week-end after a long and hard work-week ... 8-]

Thierry.
