If for any reason, you need to replace the email sender with another name/email address, you must follow the recommendations below.
Add the following line in
/etc/postfix/main.cf . All outgoing emails will have this address in the FROM field, but the name of the sender will not be modified. Replace <FQDN> with your fully qualified domain name.
sender_canonical_maps = static:no-reply@<FQDN>
To modify the name as well, you need to create a file in
/etc/postfix/header_checks which contains this line:
/^From:[[:space:]]+(.*)/ REPLACE From: "Your Name" <firstname.lastname@example.org>
Then run the following commands:
cd /etc/postfix postmap header_checks postconf -e 'smtp_header_checks = regexp:/etc/postfix/header_checks' service postfix reload
