sender mail adapter

hi all

I have tried the mail adapter scenario on the receiver side it was working fine . but can u explain how i have to trigger an external mail coming from yahoo or gmail or any external account with attachments or without attachments.

Is it enough by giving the URL of the server can i access the e-mail or any additional configuration has to be done.

I have used the PayloadSwapBean on the receiver side it was working fine, is it the same case on the sender side also if we have to trigger an external e-mail with attachment.

Please explain with an example.

I have tried triggering e-mail with our internal microsoft exchange server it was picking all the mails in the inbox , but if i have to trigger particular mail from a person what all configurations i need to be done.

regards
