Add a Reply-To header

[julbrs]

Hi,

It seems that we are struggling to add a "Reply-To" header (which is different from the "From" header). What is the best way to define a "Reply-To"?

const message = createMimeMessage();
message.setHeader('Reply-To', contact.email);

generate the following message:

MIMETEXT_INVALID_HEADER_VALUE: You specified an invalid value for the header Reply-To

Thanks!

I am also seeing this issue

I also see the same problem with setting the Sender header.

const message = createMimeMessage();
message.setHeader("Sender", "test@example.com");

When setting "Sender", it is validating if the value is an instance of a Mailbox. When I try to import Mailbox however

import { createMimeMessage, Mailbox } from "mimetext";

I can only import the Mailbox interface but not the class, so I cannot call the Mailbox constructor to create a Mailbox.

Inspired by @yukikywong, this idea comes up to me:

message.setHeader("Reply-To", createMimeMessage().setSender("test@example.com"));

where setSender just returns a Mailbox instance.

It does work well even though be tricky.

@Gowee This seems to be a working solution for now. A dedicated message.setReplyTo({ name: ..., addr: ... }) would be more elegant though.

hey again, the Reply-To header is specially handled by the lib and proper way to add it is by creating an instance of Mailbox: msg.setHeader('Reply-To', new Mailbox('asd@asd.com')) as its just become available as of version v3.0.19. you have to import the Mailbox class: import { createMimeMessage, Mailbox } from 'mimetext'. closing this issue as it should all be resolved, open again if you face any problems.
