Recently, my business had the need to create an email account for general inquiries. Since I’m currently the only employee, the email will be sent to me, but I’d like to publish a contact email address in some instances rather than my personal email address.
The email address I decided to publish rather than my own was email@example.com. In order to avoid setting up an user account on the mail server for a user named contact (and creating a mail store for the user), I decided to create an alias for contact and set myself as the contact user. This way, when email is received by Postfix for contact, the email will be sent to my mail store in my user directory.
First check the main.cf file (located at /etc/postfix on my Ubuntu server) to find the alias file configured for Postfix. Look for the following lines.
alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases
This tell us where the aliases file is located, so we open the file and you will see something like this:
# /etc/aliases mailer-daemon: postmaster postmaster: jason nobody: root hostmaster: root usenet: root news: root webmaster: jason www: root ftp: root abuse: root noc: root security: root
I simply added
contact: jason to the file and then run the
newaliases command to inform postfix of the update of aliases file. Voila, now when messages are sent to firstname.lastname@example.org, the message will be sent to my user.
