I am tying to send email using JavaMailSender. I am able to send email to my gmail account using this configuration.
mail:
host: smtp.gmail.com
port: 587
username: xyz*****#gmail.com
password: ***************
protocol: smtp
properties.mail.smtp:
auth: true
starttls.enable: true
ssl.trust: smtp.gmail.com
But when I use another server with the following config I get this error : "com.sun.mail.smtp.SMTPAddressFailedException: 554 5.7.1 **********#gmail.com: Recipient address rejected: SASLUsername Domain and Sender Domain Are Differnet - Sender Blocked"
mail:
host: mail.xyz***xyz.com
port: 25 (or 587)
username: noreply#xyz***xyz.com
password: **************
protocol: smtp
properties.mail.smtp:
auth: true
starttls.enable: false
ssl.trust: mail.xyz***xyz.com
sockeFactory.class: javax.net.ssl.SSLSocketFactory
ssl.protocols: TLSv1
When I change starttls.enable: true I get error: javax.mail.MessagingException: Could not convert socket to TLS; nested exception is: javax.net.ssl.SSLHandshakeException: Certificates do not conform to algorithm constraints
After I remove sockeFactory.class: javax.net.ssl.SSLSocketFactory and ssl.protocols: TLSv1 I get Error : the-server-selected-protocol-version-tls10-is-not-accepted-by-client-preferences
Can anyone help me out resolving these configurational issues.

Answer 1

This is happening because Zimbra has a setting which ensures that the credentials used for sending and authentication need to be same. Please check your code to ensure that your javamail From and auth are using the same email address. This should solve the error.
