Hello @AKDEVLPR. I couldn't reproduce your bug it looks like You are missing some of Spring Integration Depedency. Although I have found that in Spring Boot 3.0.1 Spring is using jakarta,MimeMessage in place of javax.MimeMessage. I'll provide fix for working with Spring Boot 3.0.1 soon.

[ygarosCog]

If You wanna use plain text values in application.yml remove the curly brackets and the dollar sign.

Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'arunofficial302@gmail.com' in value "${arunofficial302@gmail.com}"

${arunofficial302@gmail.com} should be -> arunofficial302@gmail.com

[AKDEVLPR]

can you help me resolving this error?

[ygarosCog]

Check if password specified for emails is the correct one as the exception points out.

Caused by: jakarta.mail.AuthenticationFailedException: failed to connect, no password specified?

[AKDEVLPR]

i checked them it was correct cridentials only

[AKDEVLPR]

Even though the username and password are correct it shows error only

[ygarosCog]

As far as I know Google doesnt allow You to log in in App by username and password only. You have to create an App Key and use it as password.

[ygarosCog]

Be sure that You enabled the IMAP protocol inside gmail as the app is using it.

[AKDEVLPR]

i have enabled those imap protocol but now i am facing connection errors:

" com.sun.mail.util.MailConnectException: Couldn't connect to host, port: imap.gmail.com, 993; timeout -1; nested exception is: java.net.ConnectException: Connection timed out: connect" what should i do?

[ygarosCog]

Please confirm that You do not have any other connectivity errors. Try pinging the imap.gmail.com:993 to check whatever You are getting timed out all the time, otherwise You can try to cut "@gmail.com" from email and use only the first as email_username (abc@gmail.com I mean the "abc").
