Make postfix relay through plain smtp authenticated account and Mutt
How send plain SMTP authentication with postfix. I had to tested this on centos 7.3 with Selinux and iptables disabled. Prerequisites: yum install cyrus-sasl cyrus-sasl-plain cyrus-sasl-md5 postfix -y Edit postfix configuration (vi /etc/postfix/main.cf): relayhost = [smtp.myserver.com.br]:587 smtp_use_tls = yes smtp_sasl_auth_enable = yes smtp_sasl_type = cyrus #smtp_sasl_mechanism_filter = plain, login smtp_sasl_mechanism_filter = login, plain, md5 smtpd_sasl_auth_enable = yes smtpd_sasl_path = smtpd smtp_cname_overrides_servername = no #smtp_sasl_security_options = noplaintext, noanonymous smtp_sasl_security_options = noanonymous smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_tls_CAfile = /etc/ssl/certs/ca-bundle.crt Some say server should be between [brackets], but not my case. In /etc/postfix/sasl_passwd you should set the user/password you want to use: your.smtp.server:25 user.name:password Generate the map file: postmap hash:/etc/postfix/sasl_passwd to test: open new terminal and put: tail -f /var/log/maillog and in another terminal send a test: echo "testing mailing" | mail -r 'reportservices@.myserver.com.br (Report Borg)' -s 'teste' user@myserver.com.br if is ok, go to mutt for send HTML mail first edit .muttrc and putting:
set from="Report Services <reportservices myserver.com.br="">" send-hook . "my_hdr From: Report Services <reportservices myserver.com.br="">" set from = "Report Services <reportservices myserver.com.br="">" set realname = "Report Services" set content_type=text/html set use_from=yes set envelope_from ="yes" test if is Ok: echo " <html class="exame" lang="pt-BR"> <head></head>" > /tmp/report_borg.html echo "<body><pre 12px="" font-name:arial="" font-size:="">" >> /tmp/report_borg.html echo "==========================[Espaço em disco]====================================" >> /tmp/report_borg.html df -h >> /tmp/report_borg.html echo '</pre></body></html>' >> /tmp/report_borg.html /usr/bin/mutt -s "[BKP] Borg Backup"`date +%d-%m-%Y::%Hh%Mm%s` -F /root/.muttrc borg@myserver.com.br < /tmp/report_borg.html
