问题 So our system is sending us email notifications regarding specific incidents. The problem is, things get really spammy and disorganized, and we really want to have our email client (Gmail) thread notifications regarding the same incident. So for instance: Email 1 is sent about incident 1. Email 2 is sent about incident 1. Gmail displays them in their own threads while we want them to appear as "replies" in the same thread. I thought all I needed was to append "Re: Subject Line" but that doesn

Handling of List-Unsubscribe callbacks on server

问题 When adding 'List-Unsubscribe' email headers, what kind of handling is required on the server-side for the callbacks? It's possible to add both a mailto-link and a web-link to the header, in PHPMailer it could look like this: $email->AddCustomHeader("List-Unsubscribe: <mailto:unsubscribe@example.com?subject=Unsubscribe>, <http://example.com/unsubscribe.php?unsubscribeid=$id>"); But does the mailto-address have to somehow automatically handle the unsubscription, or is it okay if the request

Does order in email headers indicate which MTA inserted each?

有些话、适合烂在心里 提交于 2021-01-28 08:06:18
问题 I'm trying to analyze a mail header to figure which element (MUA, MTA...) creates each. My supposition is: The sender MUA composes the body (including Content-Type, Mime, Content-Transfer-Encoding), and sends it via SMTP to the sender border MTA. MUA provides info for the the initial headers (From, To, Reply-To, ) which are inserted by this MTA This MTA inserts MessageID and Return_Path (and all extra headers and X-Headers it desires) Then it starts 'hoping'. On each hop the receiving MTA

Encrypting Headers S/MIME message/rfc822

问题 I am looking to encrypt certain mail headers ( Subject and Reply-To ) which are being sent in an encrypted mail. I am taking an entire MIME (Headers included) and successfully encrypting it. I can send this S/MIME encrypted mail to my mail client (Thunderbird) successfully. It will be successfully decrypted and verified as signed. However, any headers that are sent in the inner encrypted MIME are not being used by my mail client. According to RFC-5751 I should be wrapping my mail in a message

E-Mail Header: MIME-Version: 1.0 - When should this be used?

自作多情 提交于 2020-04-29 12:13:05
问题 This could be rightfully construed as a beginner's question. Consider the following e-mail header: MIME-Version: 1.0 My Questions: When should you stamp an e-mail with this header? When should you omit this e-mail header? EDIT: Is it true that whenever you specify a 'Content Type' header, no matter what that content type happens to be, that you should also specify 'MIME-Version'? [This link tipped me off to the possibility.] 回答1: According to Wikipedia, you should use the 'MIME-Version: 1.0'

Email from PHP has broken Subject header encoding

落爺英雄遲暮 提交于 2020-01-26 09:43:57
问题 My PHP script sends email to users and when the email arrives to their mailboxes, the subject line ( $subject ) has characters like a^£ added to the end of my subject text. This is obviously and encoding problem. The email message content itself is fine, just the subject line is broken. I have searched all over but can’t find how to encode my subject properly . This is my header. Notice that I’m using Content-Type with charset=utf-8 and Content-Transfer-Encoding: 8bit . //set all necessary
