Google Scripts - Grab email address from bounced message and parse information

问题

Good Morning,

I am a newbie to javascript, google scripts, and regex. I have found very good information from Amit Agarwal at https://www.labnol.org/internet/gmail-bounced-email-report/29209/, but I'm having difficulty identifying what I specifically need to keep or need to update. Rather than using the bounce mailer-daemon addresses, I would like to grab the bounced messages from two labels in my gmail account (MinervaBounce and MILSBounce) and be able to differentiate which one the message came from. Any help would be greatly appreciated.

Here are the items that are needed from the bounce message:

Email date
Label name
Bounce email address
Bounce reason
Library name from message body
Bounce Message

Here is an example of the bounce message text:

The original message was received at Tue, 31 Jul 2018 07:16:38 -0400 from localhost [127.0.0.1]

----- The following addresses had permanent fatal errors ----- (reason: 554 5.7.1 < margolulubelle@gwi.net >: Recipient address rejected: user margolulubelle@gwi.net does not exist)

----- Transcript of session follows ----- ... while talking to mx.gwi.net.cust.b.hostedemail.com.:

DATA <<< 554 5.7.1 < margolulubelle@gwi.net >: Recipient address rejected: user margolulubelle@gwi.net does not exist 554 5.0.0 Service unavailable <<< 554 5.5.1 Error: no valid recipients

---------- Forwarded message ---------- From: library.noreply@library.org To: margolulubelle@gwi.net Cc: Bcc: Date: Tue, 31 Jul 2018 07:16:38 -0400 Subject: Circulation Notice From Your Library

Thank you, Lynn

Just adjust the query to your needs, it may look like this:

from:(mailer-daemon@googlemail.com OR mailer-daemon@google.com) AND (label:"SO Review" OR label:"Sample Wala")

This will get the bounce email from multiple labels (OR operator is needed to make it match on any label, not requiring that both label is found in an email). Use Users.messages: list and the query to get the list of messageID that matches your query then use threadID to get the original message before it failed to send. Lastly use Users.messages to view the details about the original message.
