sender address in eMails sent by postfix

OK - I tried several things before so maybe they work in co-incidence:

 

LTM-Version is 9.4.4 Build 73.1 HF1

 

 

all my examples are to understand as myuser@mydomain.com

 

just replace those with your user / domain

 

 

config:

 

in /etc/postfix/aliases:

 

I changed any alias from root to myuser, the last one as well -> root: myuser

 

Then use the command 'newaliases' to rebuild aliases.db

 

 

in /etc/postfix/canonical:

 

root myuser@mydomain

 

root@bigIPs_hostname myuser@mydomain

 

root@localhost myuser@mydomain

 

root@mydomain myuser@mydomain

 

root@mydomain.com myuser@mydomain

 

 

then create the map with postmap /etc/postfix/canonical

 

 

in etc/postfix/main.cf:

 

mydomain = mydomain.com

 

myorigin = $mydomain

 

relayhost = [ip.of.your.smtpserver] (mind the brackets)

 

sender_canonical_maps = hash:/etc/postfix/canonical

 

alias_maps = hash:/etc/postfix/aliases

 

alias_database = hash:/etc/postfix/aliases

 

 

then, restart postfix.

 

From that point, it worked for me...

 

 

Best Regards,
