I see there are lots of useful changes in master but not "released". Any plans for release?

I downloaded release 0.2.0 and it doesn't seem to support the -t flag. Looking at the source code, it seems like that might have been fixed in master, but not released. Are there any plans to do another release? If not, is master in a state where it could be downloaded and built manually? (If so, any tips on how to do so? I'm not a Go developer, just trying to set up MailHog to work with our application so we can test the emails that are generated.)

Applications by default may invoke sendmail with the -t and -i flags, behavior which mhsendmail supports out-of-box.

We've set mhsendmail as the default system mailer; e.g. in our php Dockerfiles

FROM php:5.6-alpine

...
## sendmail integration
ENV MH_SENDMAIL_SMTP_ADDR="smtp:1025"
RUN [ -e /usr/sbin/sendmail ] && mv /usr/sbin/sendmail /usr/sbin/sendmail.dist ; \
  curl -Lfo /usr/local/bin/mhsendmail \
    https://github.com/BlueAcornInc/mhsendmail/releases/download/v0.3.0-rc1/mhsendmail_linux_amd64 && \
  chmod +x /usr/local/bin/mhsendmail && \
  ln -s /usr/local/bin/mhsendmail /usr/sbin/sendmail

and can work around the issue by configuring the php sendmail path according to your documention. Instead of erroring if these flags are passed; do you think it makes sense to silently continue so we can skip the sendmail path configuration?

Many thanks

I attached a simplified Makefile to generate silicon m1 executable please put in the Releases
mhsendmail-0.2.0.zip

I am not a "go" native person. ( on an off topic conversation why did they make go a snap?)

It would appear that this heavily revolves on "go get" for which I receive:

go: go.mod file not found in current directory or any parent directory.
'go get' is no longer supported outside a module.
To build and install a command, use 'go install' with a version,
like 'go install example.com/cmd@latest'
For more information, see https://golang.org/doc/go-get-install-deprecation
or run 'go help get' or 'go help install'.

What does one do with this? Thanks in advance...

Newer version of Go is adding the mhsendmail in ~/go/bin/mhsendmail.

The sendmail_path should be (path)/go/bin/mhsendmail

to get the (path), cd to ~/go/bin and type pwd, copy the output and append mhsendmail to it.

For example:

(myuser is an example user, you'll get different user in your end.)

1. cd ~/go/bin, this will output: /Users/myuser/go/bin
2. Open php.ini, find sendmail_path and change the value to /Users/myuser/go/bin/mhsendmail.

Thanks

I am running following command to send a mail and it does not work

mhsendmail --smtp-addr="mailhog-service:1025" [email protected] <<EOF
From: App <[email protected]>
To: Test <[email protected]>
Subject: Test message

Some content!
EOF

I am not seeing any error messages. Alternatively I was doing it with sendmail, which works:

sendmail -S mailhog-service:1025 [email protected] <<EOF
From: App <[email protected]>
To: Test <[email protected]>
Subject: Test message

Some content!
EOF

Any ideas?

See #16

-from "[email protected]" syntax should be supported for compatibility, but its parsed as -f "rom"

Any chance we could have a new tagged release please, or confirmation that the recommended way to install is to do so from source?

geerlingguy/ansible-role-mailhog#3 has been waiting on a MailHog 0.2.0 tagged release since Oct 2015, and as I'm waiting on the change in that issue, figured I 'd ask :)

The current release has a linux_arm build but this does not work on Apple Silicon Macs. An arm64 build is necessary

Hello

Lets assume that we have this example PHP code, lets run it ;)

$ cat test_mail.php
<?php
$to = '[email protected]';
$subject = 'Test';
$message = 'Test message.';
$headers = 'From: [email protected]' . "\r\n" .
  'Reply-To: [email protected]' . "\r\n" .
  'X-Mailer: PHP/' . phpversion();
$result = mail($to, $subject, $message, $headers);
var_dump($result);

Here is the result

$ php test_mail.php
panic: runtime error: slice bounds out of range

goroutine 1 [running]:

goroutine 17 [syscall, locked to thread]:

Here is the config

$ cat /etc/php5/cli/conf.d/zz-hitmeister.ini | grep sendmail_path
sendmail_path = /usr/bin/env /home/vagrant/go/bin/mhsendmail

Looks like it is almost the same as #3 . Hope you will have time to fix it ;)

have a nice day

comment installer mailhog et sendmail sur windows
sans oublier la configuration

Hello,

This is an excellent tool, thank you. I understand that it was meant for testing but is it possible to use this so that my php webform sends mails directly to my gmail account via mhsendmail?

I saw the setting directly below in the project page and was wondering if it can accept the settings that gmail would need (shown bottom) and if so, can you give any pointers on the syntax?

./mhsendmail --smtp-addr="localhost:1026" [email protected] ...

gmail:

tls on
tls_certcheck off
auth on
host smtp.gmail.com
port 587
user [email protected]
from [email protected]
password yourgmailPassw0rd

Thanks

Just like -i, --long-i Ignored. This flag exists for sendmail compatibility. (default true),
add support for the -bs flag.

With mhsendmail installed on application container and MailHog on another, I'm unable to set smtp addr using ENV vars. mhsendmail keeps trying to use localhost:1025.

docker-compose.yml:

services:
  fpm:
    container_name: fpm
    image: php:7.2-fpm
    environment:
      - MH_SENDMAIL_SMTP_ADDR="mailhog:1025"
  mailhog:
    container_name: mailhog
    image: mailhog/mailhog
    ports:
      - "1025:1025"
      - "8025:8025"

php.ini:

sendmail_path = /usr/local/bin/mhsendmail

test call run from fpm container:

php -r "\$from = \$to = '[email protected]'; \$x = mail(\$to, 'subject'.time(), 'Hello World', 'From: '. \$from); var_dump(\$x);"

result:

error sending mail
dial tcp 127.0.0.1:1025: getsockopt: connection refused
bool(false)

running the same test from host works fine.

I am trying to use this command line utility to send emails with some recipients cc'd and bcc'd. The client does set the headers properly but it only sends the email to the from recipient as far as I can tell. Here's an example:

mhsendmail --smtp-addr='app:9000' --from=from@localhost <<BODY
From: from@localhost
To: to@localhost
CC: cc@localhost
BCC: bcc@locahost

Example
BODY

I am only seeing one RCPT TO from tcpflow when I run this.

I installed mailhog & mhsendmail on a debian 10.5 virtualbox test server, running LAMP, ISPConfig, Roundcube, and Postfix.

I configured mailhog to load at boot using /etc/systemd/system/mailhog.service and I pass a ui-bind-addr variable to make the WebGUI accessible from my host machine's web browser, using the following config:

[Unit]
Description=MailHog service

[Service]
ExecStart=/usr/local/bin/mailhog \
  -api-bind-addr 127.0.0.1:8025 \
  -ui-bind-addr 192.168.0.100:8028 \ <--- This makes MH ui visible in my host machine browser (8025 has a different service already running)
  -smtp-bind-addr 127.0.0.1:1025

[Install]
WantedBy=multi-user.target

I have confirmed mhsendmail exists at /usr/local/bin/ and I have edited the default php.ini (7.3) version used by debian 10.5 /etc/php/7.3/cli/php.ini as follows:

sendmail_path = /usr/local/bin/mhsendmail

And, I have edited /etc/postfix/main.cf as follows:

relayhost = [127.0.0.1]:1025

However, none of my test emails appear in the mailhog WebGUI interface.

Anybody know what I am missing? THX

I'm trying to use mhsendmail as a sendmail replacement for some Drupal sites, and when I try sending emails using Drupal's built-in email functionality (with PHP's sendmail_path defined as /opt/mailhog/mhsendmail, where the binary is located), I get the following error in the logs:

flag provided but not defined: [email protected]
Usage of /opt/mailhog/mhsendmail:
  -from="nobody@example": SMTP sender
  -smtp-addr="localhost:1025": SMTP server address

It looks like mhsendmail expects a nice -from=address format, but Drupal (and many other PHP apps I've encountered use -faddress to provide a from email address.

Can you add support for this format, so mhsendmail can be more of a drop-in replacement for sendmail?

no clue

I'd like to be able to specify defaults via envars within docker containers that use mhsendmail as default MTA. Reason is we have mailhog/smtp service running in a linked container. Possible? Awesome work.

The official release (v0.2.0) sendmail binary is compiled with a version of Go <1.8 which means it doesn't respect the resolvconf option options ndots:0 when performing DNS lookups.

https://groups.google.com/forum/#!msg/golang-codereviews/aSIWRSuuwDE/hRvAKeoHAwAJ

It's possible to re-compile it and publish with the latest version please?

Using the latest relase (v0.1.7) I got the following error:

panic: runtime error: invalid memory address or nil pointer dereference

Now, I'm not a go expert, but I think user != nil need to be used instead of user == nil on line 22 in main.go :

if err != nil && user == nil && len(user.Username) > 0 {
    username = user.Username
}

I kept digging deeper and deeper (I really want to use mhsendmail instead of sSMTP for my Drupal dev environments!), and found that PHP's mail() function is the culprit here, in terms of how it uses sendmail...

To reproduce, install PHP on a server, set the sendmail_path ini directive to the path to the mhsendmail binary, then create a script somewhere with the following test:

<?php
$to = '[email protected]';
$subject = 'Test';
$message = 'Test message.';
$headers = 'From: [email protected]' . "\r\n" .
  'Reply-To: [email protected]' . "\r\n" .
  'X-Mailer: PHP/' . phpversion();
$result = mail($to, $subject, $message, $headers);
var_dump($result);
?>

If you run the script by accessing it through a webserver, check the webserver's error logs; you should get a message missing recipient, from mhsendmail.

The problem is that it seems mhsendmail is expecting the recipient as one of the command line args, but PHP's mail() function passes the recipient as a line in the header ('To: [recipient]'). See php-src: https://github.com/php/php-src/blob/fc33f52d8c25997dd0711de3e07d0dc260a18c11/ext/standard/mail.c#L356-L361

I think if you can make it so mhsendmail accepts the To address as the first line of stdin, it might work...

I'm trying out this sendmail for development and found a problem with using it through PHP's mail() function. The standard way to specify recipients seems to be to put them in the message headers and if there are more than one, separate them by commas. Unfortunate thing is that the format is not as simple as #21 proposes, specified in RFC 822 and RFC 1123 and witnessed for instance by this Go EML parser unit tests (but it doesn't cover many problematic cases either).

I don't mean to add complexity to mhsendmail, but without additional parsing net/smtp.SendMail() just fails with 501 Error: Bad recipient address syntax in this case.
