Parse inbox in Postfix using Java

问题

I am using Postfix as a mail server and I configured it to receive emails to some destination.

I want to make a Java code that parse the incoming emails and do some action. Any idea where to start or what to use?

回答1:

I see two approaches:

• Parse the mailbox (or mail) itself using jcup or jflex for instance
• Add an imap server and use some java lib to query the imap server. (it can provide you filters for instance)

The imap approach lets you select unread mail, mail by id (single or multiple), move mail from one directory to an other, and so on.

Some links:

It is for C, but tips may be helpful for java. I mean the theoretical background.

This one is a collection of imap sample with java. It seems to use a lib, but in all case, it gives you an overview of what is doable with imap.

finally, there was a question about imap and java on stackoverflow:
