I am setting up the dev environment on the M1 MBP. The PHP and NGINX are installed with the HomeBrew directly on the machine. The ElasticSearch and MailHog - with the Docker.
I am struggling to see the email in the MailHog web interface after I send one through from the PHP file. The project is working and my local PHP and NGINX communicates with the Dockerised ElasticSearch well, so I am sure MailHog is "installed" properly; I see the interface on my web on port 8025 as well.
I've played around with the php.ini file (/opt/homebrew/etc/php/7.4/php.ini
). I've double checked that ini file is the one that is used for the project (verified it with changing memory_limit
value. I've updated the Postfix (/etc/postfix/main.cf
) configuration with the following configuration too:
# For MailHog
myhostname = localhost
relayhost = [localhost]:1025
...and reloaded it like this sudo postfix reload
.
My /etc/hosts
file has this line: 127.0.0.1 l.month db elasticsearch mail
; and pinging them all works too.
When I keep the php.ini file line (containing the sendmail_path
) commented out the mail
function in PHP script works; but the email is sent directly to my real email address, not the MailHog. If I uncomment it and set it to sendmail_path = /usr/sbin/sendmail -S mail:1025
then the mail
function from PHP is returning false
. I don't understand why, since this value is advised to be used from this source. However if I use the sendmail_path = /usr/sbin/sendmail -t -i
PHP again works, but the MailHog doesn't intercept anything. I've double checked that the real path for the sendmail
is /usr/sbin/sendmail
by executing the command which sendmail
.
I also played around with the SMTP
value and the smtp_port
(in same ini file); I changed values from localhost
to 127.0.0.1
and mail
; and the 25 to 1025 respectively. I didn't forget to restart my PHP service after each change either.
Furthermore, I experimented with the postfix configuration values by changing localhost
to 127.0.0.1
and mail
(as well as reloading it) as well; no luck.
To make sure I tried all of it, I also logged out and logged in to my account to make sure the changes take place; no luck again.
I assume that I do not need the mhsendmail
file on my local if I have the docket container running, so I never installed it, hoping it is in the docker container; otherwise, then what's the point of the container after all? If I am wrong with my assumption, please let me know.
Regarding logs, no errors are shown; only this message:
[05-Aug-2022 13:11:24 UTC] mail() on [/Users/[path_here]]src/pub/mail.php:3]: To: [email protected] -- Headers: -- Subject: Test Subject
FireWall is disabled on the machine.
Please help me solve my problem so that I could see the email send from the PHP in the MailHog web interface. Thanks!
CodePudding user response:
I found the issue. Found because decided to go with the workaround - downloaded the MailHog with the HomeBrew instead of using Docker. But it didn't work! I realised I forgot to download the mhsendmail
since I am using the local MailHog.
Then it hit me! I googled this: do i need to install mhsendmail if I use docker
. And I got the answer: No, mhsendmail is not included in the mailhog/mailhog docker container. You will need to download mhsendmail (by either curl or go get) in the container that you are planning to send email from.
So apparently I was wrong to assume that MailHog comes with the mhsendmail
binary.
It started to work when I downloaded one and updated the postfix config file to:
myhostname = localhost
relayhost = [127.0.0.1]:1025
I didn't even need to touch the php.ini! The sendmail
line can stay commented out!
I hope this answer helps others as well!
