Using Sendmail for Yahoo and Google

William Park · 03-28-2017, 07:09 AM

Hi,

Yahoo and Google are pestering me to use SSL/TLS to access my accounts. I currently use fetchmail for POP3/IMAP and sendmail for SMTP. It's easy with fetchmail, just use "ssl" keyword. But, sendmail configuration is pain, so I'm still using "PLAIN" method.

Does anyone know any tutorial on how to
- configure sendmail for Yahoo/Google accounts, and
- create my own certificates?

Sendmail configuration is a pain. That's why I used fetchmail, which can be configured to use ssl rather easily. Here's an excerpt from my .fetchmailrc file.

Code:

poll imap.gmail.com protocol imap port 993 user "[username]@gmail.com" password "[password]" options ssl

I found an article about gmail, sendmail, and ssl. Maybe it will help.

Several months ago when the hosting provider for my Web pages and email advised transitioning to SSL/TLS, I found msmtp to be easy to configure. Even nicer is that the rc file resides in my home directory as .msmtprc. As I use Mutt, this works well.

Code:

# msmtp user configuration file

# A system wide configuration file is optional.
# If it exists, it usually defines a default account.
# This allows msmtp to be used like /usr/sbin/sendmail.
account default

from user@mailhost.com
domain mailhost.com

# The SMTP smarthost.
host mail.mailhost.com

port 465

auth login
user user@mailhost.com
password BigSecret

# Use TLS.
tls on

tls_starttls off
tls_trust_file /etc/ssl/certs/ca-certificates.crt

Whether this will work for Gmail or Yahoo, I don't know.

I found that msmtp honors /etc/aliases for local delivery of daemon mail and such.

Configuring Mutt is quite easy:

Code:

set sendmail="/usr/bin/msmtp"

Even the stock mailx may be is sufficient, it's also tls capable. Here is an gmail-config example.

ssmtp is the third choice. It was gmail-compatible last time I checked, which was admittedly a few years ago.

You don't need to set up an MTA just to relay to someone else' SMTP server.

If you really want to, though:

sendmail->gmail howto

postfix->gmail howto
