Passing reply-to in header for mailgun
-
When using Post SMTP with Mailgun, forms sent from plugins such as the popular Gravity Forms do not pass their reply-to address to Mailgun.
-
I have been trying to troubleshoot this exact issue, and we are using sendgrid. This has been an issue on and off for the past several months. We also have found a lot of emails are sent without the From: Name populated.

Please download the dev version from here:
https://downloads.www.ads-software.com/plugin/post-smtp.zipupload it manually and update me if the issue resolved.
Thanks @yehudah! I have tried the dev version. Both the From: field and the Reply-To: fields are not recognized in Gmail.
Here’s what the relevant header looks like:
Content-Type: text/html; charset=us-ascii Date: Thu, 29 Nov 2018 22:30:33 +0000 (UTC) From: Mime-Version: 1.0 Reply-To: [email protected] To: [email protected]Effectively if I reply to the email in gmail, it contains no To: address. When the email arrives, it has nothing in the From: name in gmail.
It appears the Reply-To is populated, however the From: and Mime-Version pieces are causing some issues on the receiver side.

This is the conversation between Postman and the mail server. It can be useful for diagnosing problems. DO NOT post it on-line, it may contain your account password. https://api.sendgrid.com:443 --Raw message follows-- SendGridMail Object ( [namespace:protected] => SendGrid [from] => SendGridEmail Object ( [name:SendGridEmail:private] => "[email protected]" [email:SendGridEmail:private] => [email protected] ) [personalization] => Array ( [0] => SendGridPersonalization Object ( [tos:SendGridPersonalization:private] => Array ( [0] => SendGridEmail Object ( [name:SendGridEmail:private] => [email:SendGridEmail:private] => [email protected] ) ) [ccs:SendGridPersonalization:private] => [bccs:SendGridPersonalization:private] => [subject:SendGridPersonalization:private] => [headers:SendGridPersonalization:private] => [substitutions:SendGridPersonalization:private] => [custom_args:SendGridPersonalization:private] => [send_at:SendGridPersonalization:private] => ) ) [subject] => Subject, Redacted [contents] => Array ( [0] => SendGridContent Object ( [type:SendGridContent:private] => text/html [value:SendGridContent:private] => content-of-email-redacted ) ) [attachments] => [template_id] => [sections] => [headers] => [categories] => [custom_args] => [send_at] => [batch_id] => [asm] => [ip_pool_name] => [mail_settings] => [tracking_settings] => [reply_to] => SendGridReplyTo Object ( [email:SendGridReplyTo:private] => [email protected] [name:SendGridReplyTo:private] => ) )I really appreciate your time and help on this, I discovered Gravity Forms has its own Sendgrid addon, tried it out and it works perfectly. Might be something to look at to fix this issue longterm within this plugin.
To OP: they also have one for Mailgun.
