All;
I started setting up a sendmail server, but have now switched to a
sendmail server.
I setup a new Fedora 37 server VM and have taken these steps per
https://fedoramagazine.org/use-postfix-to-get-email-from-your-fedora-system/
1)
# dnf install postfix mailx
2)
# MY_EMAIL_ADDRESS=my_user@my_fastmail_domain.com
# MY_EMAIL_PASSWORD=abcdefghijklm #( I entered the actual 'app password'
here
# MY_SMTP_SERVER=smtp.fastmail.com
# MY_SMTP_SERVER_PORT=465
# echo "[$MY_SMTP_SERVER]:$MY_SMTP_SERVER_PORT
$MY_EMAIL_ADDRESS:$MY_EMAIL_PASSWORD" >> /etc/postfix/password_maps
# chmod 600 /etc/postfix/password_maps
# unset MY_EMAIL_PASSWORD
# history -c
3)
updated the main.cf file:
relayhost = [smtp.gmail.com]:587
smtp_tls_security_level = verify
smtp_tls_mandatory_ciphers = high
smtp_tls_verify_cert_match = hostname
smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/password_maps
My /etc/postfix/main.cf now looks like this:
# cat /etc/postfix/main.cf
compatibility_level = 3.7
queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
mail_owner = postfix
inet_protocols = all
mydestination = $myhostname, localhost.$mydomain, localhost
unknown_local_recipient_reject_code = 550
relayhost = [smtp.fastmail.com]:465
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
debug_peer_level = 2
debugger_command =
PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
ddd $daemon_directory/$process_name $process_id & sleep 5
sendmail_path = /usr/sbin/sendmail.postfix
newaliases_path = /usr/bin/newaliases.postfix
mailq_path = /usr/bin/mailq.postfix
setgid_group = postdrop
html_directory = no
manpage_directory = /usr/share/man
sample_directory = /usr/share/doc/postfix/samples
readme_directory = /usr/share/doc/postfix/README_FILES
smtpd_tls_cert_file = /etc/pki/tls/certs/postfix.pem
smtpd_tls_key_file = /etc/pki/tls/private/postfix.key
smtpd_tls_security_level = may
smtp_tls_CApath = /etc/pki/tls/certs
smtp_tls_CAfile = /etc/pki/tls/certs/ca-bundle.crt
smtp_tls_security_level = verify
meta_directory = /etc/postfix
shlib_directory = /usr/lib64/postfix
smtp_tls_verify_cert_match = hostname
smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/password_maps
and my /etc/postfix/password_maps file:
# cat /etc/postfix/password_maps
[smtp.fastmail.com]:465 my_username@my_fastmail_domain.com:abcdefghijkl
when I run a test like this:
# echo 'It worked! 4' | mail -s "Test: $(date)" user@xxxxxxxxxxxxxx
No mail ever shows up,
thanks in advance for any help
