Hi 

I would like to set up a 'mailcluster' under IDA sendmail, so that
outbound mail has a unique mailname ( works fine when using MAILNAME ),
and having a mailserver, which delivers local mail. ( works fine with
MAILSERVER ).

My problem is a follows:

User 'aaa@fstgsg01.tu-graz.ac.at' mails to
'bbb@fm11hp01.tu-graz.ac.at'. His From header would look like
this 'aaa@oanstu-graz.ac.at', because MAILNAME has rewritten it.
'bbb@fm11hp01.tu-graz.ac.at' replies to 'aaa@oans.tu-graz.ac.at' and 
mail from 'bbb' ist sent to 'aaa@oans'. 'oans' is only a MX record,
which  points to the mailserver. The mailserver holds an alias file,
which delivers incomming mail. This already works. 

But I must have an alias entry for any user at any client, so that
incomming mail from the mailserver is delivered locally, otherwise there
would be an infinite loop. mailserver delivers to client, client looks
up the alias file, finds no entry, sends mail to mailserver, cause he
believes of local delivery, mailsver sends to client .....


Question: Is there an easier way, than to have a alias file on any
machine with alias entry for any user.

I would like to have one alias file on the server, and none or small on
all clients.


Thanks in advance
