Groovy MailService getting source code of sent email - email

Question

I am using Groovy mailService for sending emails.
For logging purpose I want to get the plain text of the email sended (like you can see in an email programm).
Code:
mailService.sendMail {
async true
to mTo
subject mSubject
from mFrom
html outFile.getText()
}
Is it possible to get the generated mail?
Best regards,
Peter

Answer 1

Found a simple solution:
MimeMailMessage mailret = mailService.sendMail {
multipart true
async true
to mTo
subject mSubject
from mFrom
html mBody
attachBytes filename, filetype, outFile.getBytes()
}
mailret.mimeMessage.writeTo(System.out)

Answer 2

You can simulate what the service internally does by (do this in a service or somewhere available for Spring processing):
MailMessageBuilderFactory mailMessageBuilderFactory
GrailsApplication grailsApplication
...
def getMessage () {
Closure callable = {
async true
to mTo
subject mSubject
from mFrom
html outFile.getText()
}
MailMessageBuilder messageBuilder = mailMessageBuilderFactory.createBuilder(grailsApplication.config.grails.mail)
callable.delegate = messageBuilder
callable.resolveStrategy = Closure.DELEGATE_FIRST
callable.call(messageBuilder)
println messageBuilder.message // (your 'MailMessage' message printed out here)
}
