I am having a challenge,I am unable to extract a unique field from emails sent directly from Safaricom Internal Mails to our Customer Service Mailbox.
All other mails received from different senders have the unique field: Message ID - As seen below;
From: John Doe <[email protected]>
Message-ID: <[email protected]>
Subject: Test Mail'
However, mails sent from Safaricom external emails ie [email protected] have the unique identifier Message ID.
I am using PHP Laravel Imap.
I would like to know if there's an extra unique field that identifies unique emails. Or if there's a way to obtain the Message ID.
