 Posted: Sat Apr 12, 2003 2:13 pm Post subject: Chaning hostname in postfix? |
 |
|
Hello!
I set up postfix and mutt, but i want my e-mail to come from mail.somedomain.tld, instead of my hostname. mail.somedomain.tld points right at my computer, so it should be fine. I set both myhostname and mydomain to mail.somedomain.tld in my main.cf file, but it still is using my hostname.
any clues?
thanks!

Hi,
maybe postfix' sender canonical option is right for you:
You have to set up a file called "sender_canonical", and put it under /etc/postfix with the following syntax:
| Code: |
username you@whatyouwant.com
|
After that you have to run
| Code: |
#postmap /path/to/sender_canonical
|
to build sender_canonical.db
Then restart postfix with
Now Postfix will rewrite every mail from username to you@whatyouwynt.com.

I followed you instructions on the sender_canonical file, and while it looks like it is exactly what I want, when I followed your instructions, nothing happened. Are there any other files I would have to modify, perhaps a setting in main or master.cf, or perhaps have to have a third cf file based off one of the sample cf files?

Hi,
Of Course that will not work - you also have to edit your main.cf and put the following in there:
| Code: |
sender_canonical_maps = hash:/etc/postfix/sender_canonical
|
After that reload Postfix again. I think it should work.
Ciao

i typed that in and it didn't work. are you sure that's the right command? any other ideas of how I can get the from field from the emails sent from my server to read user@my.custom.domain.org rather than user@ugly.hostname.from.my.isp?

Hm, on my mashines it works like that.
Doublecheck everything, and don't forget to reload Postfix.
Have a look at the maillog file.
This link's explains everything in detail:
http://www.postfix.org/rewrite.html#canonical
http://www.postfix.org/canonical.5.html
Hope it will work !
Ciao

Have you set the option: set use_domain and/or set hostname="somedomain.tld" in your .muttrc file?
Another possibility is to use the masquerade option in Postfix.
See /dir/of/postfix/install/sample/sample-rewrite.cf for the masquerade_domains variable (usually /etc/postfix/sample/sample-rewrite.cf has the info).
