Thats why I am so unsure of myself. i feel that MailMessage is a little heavyweight and that a lighter abstraction may be better but this is a minority opinion. providing that the MailMessage implementation is lazy loaded (in other words, the headers and the body are loaded only when needed) then there is really no need for a separate abstraction to achieve what you need. > > ATM fetchmail uses javamail so this usually depends on sun's > > implementation. it is possible (though unlikely) that the body will > > not be downloaded until it's needed. sniffing the protocol exchange > > should tell you whether it does. > Today, I didn't had much time to investigate, but as far as I remember > there was sample mailets adding text to the body of the message, thus, > meaning the whole message is downloaded and then given to the mailet > chain. However, I will look more when I have the time. the question is whether sun's MimeMessage implementation for POP3 is lazy loading (and so will only load the body when a method call requires it). if the MimeMessage implementation is lazy loading then the content will not be downloaded until needed. if sun's implementation is not lazy loading then it may be necessary to create a new implementation of MimeMessage based on commons net which is. - robert
