html email rendering as plain text #22

Open adamaltman opened 9 years ago

adamaltman commented 9 years ago

When MailHog receives an email, which is html, it renders it as "plain text". I don't know why this happens, and how to render it as html.

Here is an example of part of the headers, as well as a screenshot: 

Content-Transfer-Encoding: quoted-printable
Content-Type: text/html; charset=utf-8

selection_218

ian-kent commented 9 years ago

Thanks @adamaltman, does this happen with all HTML messages or just occasionally?

I can sort of reproduce it, but only when the HTML email follows a plain text email. When it happens, the broken HTML message contains the previous plain text email at the start (and I assume the headers), which is why MIME parsing fails. I'll fix that anyway, but does it sound like it might be the same bug?

adamaltman commented 9 years ago

Right now it happens with all HTML messages.

ian-kent commented 9 years ago

Ok thanks, I'll have another look

Out of interest, do you know if the SMTP client is using pipelining?

adamaltman commented 9 years ago

Ian - I'm not sure. The client is a php web application. The library it uses for email is: http://swiftmailer.org/

ian-kent commented 9 years ago

No problem, thanks, I'll see if I can reproduce it a bit more consistently.

jygastaud commented 9 years ago

I have the same issue with a Drupal (PHP) website + PHPMailer library. Mails in (real) inbox as Gmail are display fine but MailHog seems not to understand it. Plain text with HTLML structure are displayed.

ian-kent commented 9 years ago

Would either of you be able to provide MailHog logs demonstrating the bug so I can replay the SMTP conversation against my MailHog to reproduce it?

If you don't want to post it here, if possible could you e-mail them to me instead? email@iankent.co.uk

Thanks

JanStevens commented 9 years ago

I have the same issue using a Rails application, i'm willing to provide logs if you guide me to their location or how to log them

Thanks for this awesome program, mailcatcher is sadly not really maintained and doesn't work for ruby 2.2.0 so this is a very good alternative!

ian-kent commented 9 years ago

Thanks @JanStevens, that would definitely be useful!

It'll depend on how you're running MailHog - if its from the command line, the logs should be going to STDOUT, so redirecting to file or piping to tee should work.

Let me know if its Docker and I'll give it a go, to be honest I hadn't even considered how logging would work for the Docker container builds (and I'm no Docker expert!!).

ian-kent commented 9 years ago

I'll keep this open for now, but I hope the latest release has fixed it - but couldn't reproduce it reliably anyway so not entirely sure.

jygastaud commented 9 years ago

Sadly, no. At least in my case.

MailHog version: 0.1.2 Linux amd64 OS: Debian 7

I will sent you a log file in a minute.

ian-kent commented 9 years ago

Think I've got it this time, but I'll keep the issue open for now

jygastaud commented 9 years ago

Great work Ian. Works for me in 0.1.3

JanStevens commented 9 years ago

Oke still doesnt work for me, I've send you an email with the output. If you need more information then please let me know! thanks!

ian-kent commented 9 years ago

Thanks @JanStevens, I'll have a look asap.

chuntley commented 9 years ago

I'm having this same issue. The headers look correct but the email is being rendered in plain text. Is there a way to force all emails to be rendered as HTML as a workaround?

4lyn commented 8 years ago

Same problem here. All my emails seen as plainText. It would be the perfect tool otherwise

ian-kent commented 8 years ago

Thanks for the updates @chuntley @4lyn - could you provide example SMTP messages plus the log output for MailHog receiving them.

4lyn commented 8 years ago

Simple php code :

$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=UTF-8' . "\r\n";
$headers .= 'From: Test <noreply@test.fr>';
mail('test@test.fr', 'Test html email', '<html><body>This should be html email<br/>Thank you</body></html>', $headers)

I only see the "Plain text" and "Source" Tab in the MailHog web interface

+1 Happens for me too

crazy-max commented 8 years ago

+1 For me too with the basic example from PHP website Example #4 Sending HTML email.

mail

akreal commented 8 years ago

I think the problem is that some messages have Content-type header, while MailHog checks only Content-Type one: https://github.com/mailhog/MailHog-UI/blob/master/assets/js/controllers.js#L461

4lyn commented 8 years ago

Nice shot ! It works for me now. Thanks a lot !

crazy-max commented 8 years ago

Maybe we can add an other control over the content (html tags) if the Content-type is blank ?

jehon commented 7 years ago

I have the same problem with a Drupal installation sending emails.

Looking a bit in the Drupal system, I see that it send content-type with a lower "t".

Is it possible to fix this?

nortmas commented 7 years ago

I think the problem is that some messages have Content-type header, while MailHog checks only Content-Type one: https://github.com/mailhog/MailHog-UI/blob/master/assets/js/controllers.js#L458

Guys, it's still not fixed. Can anyone fix this please?

nortmas commented 7 years ago

How to find controllers.js locally (Ubuntu)? Can't find it. Could someone help me please?

jehon commented 7 years ago

Still interested in a fix of this one...

How could I help?

nortmas commented 7 years ago

Can you fix this line - https://github.com/mailhog/MailHog-UI/blob/master/assets/js/controllers.js#L458

Instead of this: if (message.Content.Headers && message.Content.Headers["Content-Type"] && message.Content.Headers["Content-Type"][0].match("text/plain")) {

need to use something like this:

if ( message.Content.Headers && ( (message.Content.Headers["Content-Type"] && message.Content.Headers["Content-Type"][0].match("text/plain")) || (message.Content.Headers["Content-type"] && message.Content.Headers["Content-type"][0].match("text/plain")) ) ) {

Because some messages have "Content-type" header, while MailHog checks only "Content-Type"

Also I can't find controllers.js locally (Ubuntu) to fix this file. Do you know the location where I should search?

ian-kent commented 7 years ago

Sorry, thought I'd fixed this... https://github.com/mailhog/MailHog/issues/113 turns out it was a different bug!

controllers.js is inside MailHog-UI - https://github.com/mailhog/MailHog-UI/blob/master/assets/js/controllers.js

there's a bunch of places where it treats headers incorrectly - more than happy to accept a PR to fix this one, but otherwise I'll have a look at cleaning that mess up asap!

edit: afaik, to be RFC compliant in its header handling it can just lowercase everything before the comparison/lookup (I think it was defined in RFC822, but seems to be missing from the updated RFC2822 and RFC5322 - if anyone knows where its now covered it'd be a great help!)

timmetj commented 7 years ago

Any news on this? Also seeing everything in plain-text

Barry-Fisher commented 7 years ago

I'm finding that HTML tab doesn't display on version 0.2.1-4 - only the Plain text and Source tabs. The email body looks like:

This is a multi-part message in MIME format.

The Content-Type header appears to have the right case to match the javascript. I'm also using Drupal and the PHPMailer library.

Does anything appear glaringly obvious that I'm missing here?

I'm also seeing HTML emails in plain text.

Experiencing this consistently today with a Woocommerce site. If I have time I will help troubleshoot but does anyone want logs if I supply them?

webdobe commented 5 years ago

I am getting this as well with a Drupal 8 docker install. Regardless if I send in html or not. Been debugging, but not getting anywhere. I changed some info to remain anonymous, I see the mailhog.example.. not sure If that is causing the issue?

@hellerbenjamin Thanks I will use this.

Hi, I'm facing similar issue as the mail body is shown encoded. I'm using mailer lib from dart image image

smustgrave commented 3 years ago

I'm also experiencing this issue in Drupal if anyone has any suggestions. I'm using https://www.drupal.org/project/swiftmailer to send HTML emails but no luck.

Using MailHog with plain PHP and having the same issue. Using Content-Type: text/html;charset=utf-8 and all emails are coming in as plain text instead of HTML.

vandijkstef commented 3 years ago

Having the same issue also using UTF-8. Interesting; The 'MIME' tab shows and it shows each part as 'unknown'. When downloading the email as EML file, and opening it in apple mail, it renders as expected.

I'd love to drop a mailhog version, but 'mailhog --version' doesn't give a number, its blank.

nkboscia commented 3 years ago

Same issue. Using multi-type emails and it doesn't display the HTML tab at all and the MIME type just gives an error: Error: null is not an object (evaluating 'data.MIME.Parts.length')

Content-Type: multipart/alternative; boundary="1623876169.D35aAB6D0.32925"; charset="us-ascii" MIME-Version: 1.0

MIME-Version: 1.0 Content-Type: text/plain; charset="UTF-8"

I put a paid bounty on this in hopes it'll get bumped in priority.

tecbird commented 3 years ago

try to prepand body an "\r\n". in my case mailhog is now extracting data correct from message source....

nkboscia commented 2 years ago

The mail receive identifies to parse on the boundary just fine, but the web interface just throws everything into the plain text tab and ignores the boundary and Content-Type headers.

leymannx commented 2 years ago

Colleague of mine had the problem with Swiftmailer/Drupal. When they changed the "Sender" to use the "Default PHP Mailer" and keep just the "Formatter" using "Swiftmailer" it suddenly worked.

stefumies commented 2 years ago

This is still an issue in Summer 2022, I cant see how this will allow us to continue with Mailhog. Any updates? I have the issue from nodemailer

michaeljauk commented 1 year ago

Also having the same issue with nodemailer: ^6.7.8
