I am attempting to setup so I can mail from Raspbian.
When I attempt to send I get an error
ssmtp: Cannot open smtp.gmail.com:587 (I also tried port:465)
I have set "Access for less secure apps" on Google and can send/receive from the account on Thunderbird.
I have installed
ssmtp and configured
/etc/ssmtp/ssmtp.conf to contain:-
# Config file for sSMTP sendmail # # The person who gets all mail for userids < 1000 # Make this empty to disable rewriting. email@example.com # 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 AuthUserfirstname.lastname@example.org AuthPass=xxxxxxxxxxxxxx UseTLS=YES UseSTARTTLS=YES # Where will the mail seem to come from? rewriteDomain=gmail.com # The full hostname email@example.com # Are users allowed to set their own From: address? # YES - Allow the user to specify their own From: address # NO - Use the system generated From: address FromLineOverride=YES
I have also configured
/etc/ssmtp/revaliases to contain:-
# sSMTP aliases # # Format: local_account:outgoing_address:mailhub # # Example: root:firstname.lastname@example.org:mailhub.your.domain[:port] # where [:port] is an optional port number that defaults to 25. root:email@example.com:smtp.gmail.com:587
Edit The settings above based on https://wiki.archlinux.org/index.php/SSMTP
I have done some further testing.
I selected a different SMTP server, which worked. (I do not want to use this, as it is only available when directly connected to my ISP.)
I tried setting an Application Specific password, and got the response"The setting you are looking for is not available for your account". (Presumably because this account does not have 2-factor authentication.)
The gmail account I am trying to use was specifically created to send messages from the Raspberry Pi.
