AFAIK (but I haven't tested it personally) you can specify: smtp:[mail.magma.ca]:587 in your transport_maps file. The [] disables MX lookups. eg. in main.cf transport_maps = hash:/etc/postfix/transport And then something in /etc/postfix/transport like: # Mappings for routing mail based on destination # Execute 'sudo postmap /etc/postfix/transport' after modifying # # line one means deliver mail for user@localhost locally # line two means deliver mail for user [ at ] yourdomain [ dot ] com locally # line three means deliver mail for user [ at ] subdomain [ dot ] yourdomain [ dot ] com locally localhost : yourdomain.com : .yourdomain.com : # The next line means relay mail for everyone else through Magma's server * smtp:[mail.magma.ca:]587 Make sure you read and understand: http://www.postfix.org/BASIC_CONFIGURATION_README.html and http://www.postfix.org/STANDARD_CONFIGURATION_README.html as this example file makes some assumptions about local delivery you might not want and does not allow for virtual domains (if applicable). Your magma info is from this source? http://businesssupport.primus.ca/magmaemail.cfm FWIW I am currently using TLS and it is working for me (assuming you _want_ encryption) but to enable TLS more work is required, see: http://www.postfix.org/TLS_README.html specifically SMTP Client specific settings HTH, Jim
