sSMTP no longer works - 'Invalid response: 501 5.5.4 HELO/EHLO argument [email protected] invalid, closing connection.'

As the title/tags say, I run sSMTP on Linux for a PHP server.

Whenever I try to send an email, I get these errors (that do not show up in PHP, only in the logs/ 'sudo service sendmail status' or 'sudo service php5-fpm status')

From /var/log/mail.log

Mar 31 03:34:34 ip-172-31-22-38 sSMTP[2004]: Creating SSL connection to host

From /var/log/mail.err and mail.warn

My /etc/ssmtp/ssmtp.conf

#
# Config file for sSMTP sendmail
#
# The person who gets all mail for userids < 1000
# Make this empty to disable rewriting.
[email protected]

# The place where the mail goes. The actual machine name is required no
# MX records are consulted. Commonly mailhosts are named mail.domain.com
mailhub=smtp.gmail.com:587

# Where will the mail seem to come from?
#rewriteDomain=

# The full hostname
[email protected]

[email protected]
AuthPass=[removed]
UseSTARTTLS=YES
# Are users allowed to set their own From: address?

my ssmtp.conf included [email protected], I changed it to hostname=localhost and the problem was solved.

After pulling my hair out for ages, I finally strapped down and copied the config from Arch Linux's wiki article for Gmail and SSMTP, and that ended up working! Be sure to triple check your configs, folks!

# The user that gets all the mails (UID < 1000, usually the admin)
[email protected]

# The mail server (where the mail is sent to), both port 465 or 587 should be acceptable
# See also http://mail.google.com/support/bin/answer.py?answer=78799
mailhub=smtp.gmail.com:587

# The address where the mail appears to come from for user authentication.
rewriteDomain=gmail.com

# The full hostname
hostname=localhost

# Use SSL/TLS before starting negotiation
UseTLS=Yes
UseSTARTTLS=Yes

# Username/Password
AuthUser=username
AuthPass=password

# Email 'From header's can override the default domain?
FromLineOverride=yes
