javamail - notification if no reply to a mail in Gmail (Java) -
i know if possible know if recipient has answered definit email .
what te best way in java ?
there message-id, in-reply-to , references headers in e-mail message (see http://cr.yp.to/immhf/thread.html or http://wesmorgan.blogspot.ch/2012/07/understanding-email-headers-part-ii.html). have keep message-id of e-mail message interested in, , parse headers of incoming messages, if contain id.
as way in java, read java mail api tutorial , study javax.mail javadoc (and sub-packages).
warning: athough commonly used e-mail clients, these headers not mandatory, there no 100% secure way it.
