Users discuss a feature request related to email clients ignoring the ‘Reply-To’ header, which can cause replies to go directly to the sender instead of the intended recipient (e.g., a Discourse forum email address). ashledombos highlights this issue affects mobile email apps (including Firefox OS’s default client and some iPhone apps), though desktop clients generally handle it correctly. They note it’s not a Discourse bug but a client-side limitation, and have filed a bug report with Mozilla here. codinghorror agrees, calling ignoring ‘Reply-To’ a serious bug. ashledombos adds that while desktop apps work fine, mobile apps lack reporting channels, making fixes harder. They suggest a workaround: including the ‘Reply+{messagekey}@…’ address in the ‘From’ header as well as ‘Reply-To’ to increase compatibility. Summary: Email clients ignoring ‘Reply-To’ breaks expected reply behavior; workaround proposed to include the reply address in ‘From’ header for better mobile support.
Hello,
I know it’s not a bug of Discourse, but a missing feature in some email clients (I have three examples in mind, such as the default and, for what I know, only email client of Firefox Os) which ignore the reply-to header, and reply directly to the sender (with the address info@… for exampe in the case of discourse)
Would it be possible to let the user have the possibility to force header “from” being the same as “reply-to”, for workaround?
Ignoring Reply-To is a very serious bug indeed.
Right, but I have seen this problem on various mobile dedicated email app… Until now no problem with desktop programs I tested.
I know it’s not a problem Discourse team is responsible with, but it could be a workaround for helping the user still continue using the ml feature, until these bugs are solved by each email application providere.
For information I opened an issue ticket here 1152683 - [email] reply-to header ignored because mailbridge tries to use an array value like a singular value
For the iphone apps, it’s less easy as I did not find a place to report issues, so I made comments about the apps but not sure if they will be read by developers.
Someone replied and even changed the title of my report
Summary: reply-to header is ignored in email app → [email] reply-to header ignored because mailbridge tries to use an array value like a singular value
Not sure to understand what it means…
