postfix change sender address
How do I create a postfix table using SMTP?
Save and close the file. Create or update generic postfix table using the postmap command: When an email is sent to a remote host via SMTP this replaces tom-01@server01.hosting.com by tom@domain.com mail address. You can use this trick to replace address with your ISP address if you are connected via local SMTP or AWS SES.
How do I prevent postfix from appending a domain to a partial address?
To prevent Postfix from appending the domain in myorigin or mydomain to partial addresses, you can change the parameters append_at_myorigin and append_dot_mydomain: Under most circumstances you do not want to do this. Postfix itself assumes addresses are in the correct format, as do many other applications that handle email messages.
How does postfix fix incomplete email addresses?
Postfix also appends the value of mydomain to addresses that include only the host portion without the domain name. This fixes addresses that look like kdent@host so they become kdent@host.example.com. Postfixâs expansion of incomplete email addresses is sometimes the source of confusion for end users.
How does postfix rewrite addresses?
Rewriting Addresses - Postfix: The Definitive Guide [Book] Postfix tries to make sense of addresses in email and writes them using the standard RFC 2822 format. Certain address rewriting occurs automatically. You saw earlier in the chapter how Postfix appends myorigin to a local name that has no domain part.

Does postfix set the from address for an e-mail?
- Postfix itself does not "set" the from address for an mail (as long has you haven't really tweaked the postfix configuration). The from address header of an e-mail is set by the mail client which is asking postfix to deliver the mail (Postfix is a MTA ). Hence you are looking at the wrong place - as far as I understand your question.
What is an example of a postfix error?
- For example, when the system user oracle sends an email then postfix should rewrite "oracle@hostname" to "no-reply@example.com". When trying to deliver mail via my ISP mail relay, I get the following error in the logs: A Red Hat subscription provides unlimited access to our knowledgebase, tools, and much more.
How to re-write postfix?
- This re-write can be handled via a /etc/postfix/generic file. Then create a /etc/postfix/generic file as below and add additional users if needed. All outgoing emails from both root@myserver and userA@myserver will automatically have the FROM SMTP field sent as myaccount@myoffice356domain.com.
How do I change the from part of a mail?
- Try executing mail as a different user and you'll see the from part changed. And since the command mail does - by default - not append the domain part to the "from" header of the mail it hands over to postfix, postfix is appending the myorigin part automatically to root. Though mail is not limiting you to not use some other "from" e-mail header.
