Hallo,
I've set up a mail server using the great iRedMail. On the same server I want to setup a Mastodon instance (federated social network). I've got some questions concerning the SMTP-settings of Mastodon. The sending of email with my current settings don't work and I've got no clue why:
# E-mail configuration
# Note: Mailgun and SparkPost (https://sparkpo.st/smtp) each have good free tiers
# If you want to use an SMTP server without authentication (e.g local Postfix relay)
# then set SMTP_AUTH_METHOD and SMTP_OPENSSL_VERIFY_MODE to 'none' and
# *comment* SMTP_LOGIN and SMTP_PASSWORD (leaving them blank is not enough).
SMTP_SERVER=127.0.0.1
SMTP_PORT=587
SMTP_LOGIN=notifications@example.com
SMTP_PASSWORD=******
SMTP_FROM_ADDRESS=notifications@example.com
SMTP_DOMAIN=example.com
SMTP_DELIVERY_METHOD=smtp
SMTP_AUTH_METHOD=plain
SMTP_CA_FILE=/etc/ssl/certs/ca-certificates.crt
#SMTP_OPENSSL_VERIFY_MODE=peer
SMTP_ENABLE_STARTTLS_AUTO=false
#SMTP_TLS=trueHere comes the output of my mail.log:
