gmail smtp config error

[plguevara]

Alfresco 4.2.d Windows 7 32 bits (new installation)

I cannot configure gmail as my outbound SMTP
I have this in the alfresco-global.properties:

#Invitation Service
# Should send emails as part of invitation process.
notification.email.siteinvite=true

# Sample Gmail settings
mail.host=smtp.gmail.com
mail.port=465
mail.username=xxxxxxx@gmail.com
mail.password=xxxxxxxxx
mail.protocol=smtps
mail.smtps.starttls.enable=true
mail.smtps.auth=true

I am testing sending invitation emails to a site (Alfresco Share)
I get : 1 invitation sent: 0 Failed

I never get the mail


I get the following erro in alfresco.log:

If you are using smpts protocol you should download certificate from the remote SMTP server and install it.
1.download certificate
openssl s_client -connect smtp.gmail.com:465 -starttls smtp >gmail-smtp.cer.(you are using windows ,you can install cygwin then install openssl)
2.install certificate
sudo keytool -import -alias  smtp.gmail.com -file gmail-smtp.cer -keystore [java_home]/lib/security/jssecacerts.

Also I have noticed in your logs it shows that alfresco is trying to send test mail to this id
xxxx@aol.com
Check out where you have used this mail Id. Try replacing it with valid GmailId.
