set up sendmail on my laptop

Can I set up sendmail at home on my laptop to actually send a mail from a simple contact page html file, using PHP?

My contact page works fine from my little cloud server, just trying to make it work at home, if that can be done!

Following this tutorial, I installed sendmail and related things.

It says I must have these lines in /etc/mail/sendmail.mc

Quote:

define(`SMART_HOST', `your.smtp.server')dnl define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl FEATURE(`authinfo',`hash -o /etc/mail/authinfo.db')dnl

I believe my smtp server is: qq.smtp.com for qq mail. But I remember when I used to fetch emails with Python, I needed the IMAP server and IMAP password.

As sudo, using nano, I created /etc/mail/authinfo with the following content:

Quote:

AuthInfo:qq.smtp.com "U:me@foxmail.com" "P:topsecret" "M:PLAIN"

/etc/mail/authinfo.db did not exist but was created with:

Quote:

sudo makemap hash /etc/mail/authinfo < /etc/mail/authinfo

Also, must I start all lines in /etc/mail/sendmail.mc with dnl ???

After following all the instructions from the link above, I did this in bash

Quote:

echo "This is a test email." | mail -s "Test Email" myname@gmail.com

But I did not get the email!

Any tips please?
