Recently I have had the pleasure of migrating a WordPress website which resulted in a peculiar problem - sending email functionality on the new server no longer worked. After some digging around I found out that PHP has this mail function which uses the sendmail program to actually send your email.
Well after messing around with real sendmail for a good while and still not really understanding how to configure it properly, I decided to write my own sendmail.py script that uses my gmail and its app password to send out an email to whoever PHP/Wordpress wants to send an email to on my behalf.
After script was done I had to tell php to use it via sendmail_path = path to sendmail.py line inside php.ini which was located /etc/php5/apache2/php.ini on my Debian server. Then I just restarted apache server and voila, sending email worked!
Here is sendmail.py in all of its hacky glory:
#!/usr/bin/python #this is replacement for sendmail that php can use to send its goddamn emails import smtplib import sys def findToAddress(lines): for i, val in enumerate(lines): j = val.index("To: ") if j != -1: return val[j+4:] return "" fromaddr = 'email@example.com' lines = sys.stdin.readlines() toaddrs = findToAddress(lines) msg = ''.join(lines) username = 'firstname.lastname@example.org' password = 'your app password' # The actual mail send server = smtplib.SMTP('smtp.gmail.com:25') server.starttls() server.login(username,password) server.sendmail(fromaddr,toaddrs, msg) server.quit()
