It's often handy to dump off preferable for Ubersmith-related email to be handled by the local MTA mail container rather than talking SMTP to communicating directly with a remote SMTP host directly. It's . Mail delivery is quicker, and logging is far superior to what Ubersmith provides.This style of with superior logging, and avoids the need for the Ubersmith web interface to 'pause' or 'wait' for the mail delivery actions to complete. Ubersmith's mail container runs the Postfix MTA. This configuration is confirmed to work with : Office 365

From a shell application,

Ubersmith Mail container for Ubersmith 4.x

Copy your cacert.pem and paste , Sendgrid, and Amazon SES.

The following instructions assume that Ubersmith has been installed to /usr/local/ubersmith and that Ubersmith is being configured to relay mail to Office 365. Be sure to use the specific relayhost configuration for the provider you plan to have Ubersmith send mail to. Retrieve the latest copy of cacert.pem  from curl.haxx.se and place it in /usr/local/ubersmith/conf/mail:

• cd /usr/local/ubersmith/conf/mail;
• curl -L -O https://curl.haxx.se/ca/cacert.pem

 Go to  Open a shell within the mail container:

• cd /usr/local/ubersmith;
• docker-compose exec mail bash

Modify Within the mail container, modify /etc/postfix/main.cf to uncomment and edit the following variables to the appropriate settings:

/etc/postfix/main.cf Configuration Options

CreateStill within the container, create /etc/postfix/sasl_passwd and generate sasl_passwd.db:

• Edit /etc/postfix/sasl_passwd to contain the following:

  • [smtp.office365.com]:587    smtp-user@example.com:password

• RunTo generate /etc/postfix/sasl_passwd.db, run:
  • postmap /etc/postfix/sasl_passwd

Exit the container, and run:

• docker cp ubersmith_mail_1:/etc/postfix/main.cf /usr/local/ubersmith/conf/mail

• docker cp ubersmith_mail_1:/etc/postfix/sasl_passwd /usr/local/ubersmith/conf/mail

• docker cp ubersmith_mail_1:/etc/postfix/sasl_passwd.db /usr/local/ubersmith/conf/mail

Edit /usr/local/ubersmith/docker-compose.override.yml to add the following volumes to the mail service:

Recreate the mail container:

• tail -f /var/log/ubersmith/mail/docker.log

Legacy Instructions for Ubersmith 3.x

These instructions also appear to work for relaying to Exim and postmarkapp.com.

This guide is functional on CentOS 6, which runs a pretty ancient version of Postfix – so it should hopefully also work with newer versions and OS'es.

• Install the cyrus-sasl-plain package (or equivalent for the OS in question):

  • yum install cyrus-sasl-plain

• Grab a copy of cacert.pem and drop it off in /etc/postfix

  • cd /etc/postfix; curl -L -O http://curl.haxx.se/ca/cacert.pem

Edit /etc/postfix/main.cf and include/update the following configuration options:
/etc/postfix/main.cf Configuration Options

relayhost = [smtp.office365.com]:587
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_sasl_tls_security_options = noanonymous
 
smtp_send_dummy_mail_auth = yes
smtp_always_send_ehlo = yes
smtp_tls_security_level = encrypt
smtp_use_tls = yes
smtp_tls_CAfile = /etc/postfix/cacert.pem
 
# debug options
# debug_peer_list = smtp.office365.com

• Edit /etc/postfix/sasl_passwd to contain the following:

  • [smtp.office365.com]:587    smtp-user@example.com:password

• Run:
