![]() Still, you don't have to necessarily go with one of the advertised overachievers. Not all users would want their email client to set up reminders and double up as a calendar, but if these are things that you use daily, it's probably best to use just the one tool, rather than several. Just like on the screenshot below.The all-in-one nature of some of the clients in our collection deserves special mention. Outlook or Thunderbird) will tell you that your certificate is self-signed, and that you should not trust it. If you do not change the certificate path, when you try to send an email your client (e.g. ![]() Smtpd_tls_key_file=/etc/letsencrypt/live/$FQDN/privkey.pem Your path will look similar to the following smtpd_tls_cert_file=/etc/letsencrypt/live/$FQDN/fullchain.pem Smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.keyĬhange the above, so that it reflects your certificate obtained by the Certbot in this tutorial. Set certificate paths changing the following two lines smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem Think of it as the server saying “Helo, I’m $FQND, please accept email from me.” Additionally it configures helo handshake required to bypass spam filters. The above configures Postfix so that bots and spammers cannot send emails claiming to be you, in short. Now add the following at the bottom smtpd_recipient_restrictions =Ĭheck_helo_access hash:/etc/postfix/helo_accessĬAUTION if said entries exist then comment them out and put everything at the bottom. Again, this should be configured automatically, but I am specifying this just in case. Now modify the following two entries so that they look exactly like the below inet_protocols = ipv4 Modify main.cf file with the following command sudo nano /etc/postfix/main.cf Now you need to configure Postfix so that you can send email properly. Do not set folder permissions other than 700! Setting them to 700 means that only the owner can read, write and execute files in that directory. Run the following sudo cp -r /etc/skel/Maildir ~/ You need to copy them to your user’s home directory. The user you are currently logged in as do not have those folders just yet. Including our newly created email directories. If you create a new account everything from skel will be copied into the user’s home directory. This is a special folder that serves as a template for any new system account. The above will create mail directories in /etc/skel folder. Sudo maildirmake.dovecot /etc/skel/Maildir/.Templates ![]() Sudo maildirmake.dovecot /etc/skel/Maildir/.Trash Sudo maildirmake.dovecot /etc/skel/Maildir/.Spam Sudo maildirmake.dovecot /etc/skel/Maildir/.Sent Sudo maildirmake.dovecot /etc/skel/Maildir/.Drafts Run the following commands sudo maildirmake.dovecot /etc/skel/Maildir In my opinion, however, it is best to keep messages in the user’s home folder, each one in a separate file. There are a few ways to set up folders for your mail. Due to obvious advantages, you will set up only IMAP server, as POP3 is obsolete and not useful anymore. You can read more about POP and IMAP on Wikipedia. IMAP only synchronizes your messages so that they can be accessed by different means, they stay on the server. In short POP3 downloads all messages to a device accessing the email server, and messages are erased form the server. You really do need your machine to run 24/7.Įmail server protocols is yet another thing to be mindful of. If it cannot deliver it instantly, it just gives up telling the sender that your server is unreachable. This is because when an email is sent, a transfer server is looking up your server to deliver the message. You simply cannot just switch your server on to download stuff and turn it off again. Before we dive into the tutorial itself, you need to understand a thing or two about email servers.įirst of all, email server is a service that absolutely requires 24/7 uptime of your machine if you plan to receive emails.
