Set up MailHog development SMTP server¶
MailHog is a simple development SMPT server that can be used to test sending of emails.
1 Install¶
1.1 If using MacOS without Homebrew¶
You can install it by downloading the appropriate binary from GitHub at
https://github.com/mailhog/MailHog/releases (in case of MacOS, search
for the one containing darwin in its name). If you go that way, put
the downloaded binary as mailhog to the appropriate place that is
configured in your PATH environment variable, usually bin
directory in your home directory.
Execute the following on the command line, replacing the path with the correct one for your OS:
cd ~/bin
wget -O ~/bin/mailhog https://github.com/mailhog/MailHog/releases/download/v1.0.0/MailHog_darwin_amd64
chmod a+x ~/bin/mailhog
2 Start¶
As we don’t always need it in a project, MailHog is to be started when needed.
Execute on the command line:
mailhog
You should receive output similar to the following:
