  • Since you don't have access to gmail.com logs, I would suggest two things. First, log to gmail.com account (abc@gmail.com), look for any mailbox quota warnings, change your password and update password in Toshiba smtp client settings. If that doesn't help, use different account for authentication, it can be another gmail.com address or better, email on different domain. If that doesn't produce results, contact Toshiba support and let them check for issues on device itself. – RonanW. Jul 13 '16 at 13:30
  • seeing as there is supporting info as to why this could be an issue, I'm not sure why it was downvoted. http://googleappsupdates.blogspot.ro/2016/05/disabling-support-for-sslv3-and-rc4-for.html – Jacob Evans Jul 13 '16 at 18:01

In my experiance with toshibas/any copier, you should setup a local MTA (postfix on a vm, raspberry pi, whatever), use the pi as a smarthost relay to gmail,

Another option is to put them behind the print server (no idea how your network is setup) and install smtp relay on the windows server (iis smtp work but others exist).

If PCI/HIPPA is involved you likely need that unit upgraded or replaced to scan PIAA over your network since only TLSv1.1 and 1.2 satisfy their latest desires.

But this is why it doesn't work: http://www.infoworld.com/article/3071171/security/google-to-shutter-sslv3-rc4-from-smtp-servers-gmail.html

This is why the company I worked for built an email server just for the copiers they sold.

SMTP Server or Client

you should use one or the other, either be your own MTA and send email (which might make it an open relay on your localsubnet) or be a client, I would suggest client and the postfix relay option.

I wonder if "Failed SMTP Authentication" equates to Unable to connect to server (perhaps, the software doesn't distinguish between the two issues). It's not uncommon for ISPs to block outbound SMTP traffic, unless you're a business user. Maybe there was a recent change on their end in regards to policy. I would recommend running telnet smtp.gmail.com 25 and examining the output. If you're unable to connect, that is likely the cause of the issue.
