mhsendmail is a sendmail replacement for MailHog.
It redirects mail to MailHog using SMTP.
You can also use
MailHog sendmail ... instead of the separate mhsendmail binary.
Alternatively, you can use your native
sendmail command by providing
-S, for example:
/usr/sbin/sendmail -S mail:1025
For example, in PHP you could add either of these lines to
sendmail_path = /usr/local/bin/mhsendmail sendmail_path = /usr/sbin/sendmail -S mail:1025
