SMTP emails not being sent. Appears to be a lot of Symphony errors as well - PS1.7.7

 

Error log report

Swift Error: Failed to authenticate on SMTP server with username \"[email protected]\" using 2 possible authenticators

In searching web I find https://www.thenoccave.com/2016/02/17/swift-mailer-failed-to-authenticate-on-smtp-server-with-username/

My app/config/config.yml lists swiftmailer: as being
 

Quote

 

# Swiftmailer Configuration swiftmailer:

transport: "%mailer_transport%"

host: "%mailer_host%"

username: "%mailer_user%"

password: "%mailer_password%"

spool: { type: memory }

 

 

Whereas in the link above it shows password, encryption and port being required.

    username:  "%mailer_user%"

    password:  "%mailer_password%"<br>

    encryption: %mailer_encryption%<br>

    port:       %mailer_port%<br>

    spool:     { type: memory }<br>

 

 

Anybody have any further information or guidance as to whether this is the way to go ??
