Netbotz 450 and gmail

[DCIM_Support]

I have a customer who has their email server set up as a gmail account. I have tried all the options but just get the message "unable to send test email" and the log reports peer disconnected. The Netbotz is running version 4.3 now but was previously on 4.5 and had the same issue,

I know it isnt the network/firewall as I can send a mail succesfully from within the network from a command line ie

C:\OpenSSL-Win32\bin>openssl s_client -crlf -connect smtp.gmail.com:465

etc

etc

354  Go ahead  - gsmtp

Subject: Test Email from CREMS

Test me

.

250 2.0.0 OK  - gsmtp

Is it a supported config to use smtp.gmail.com ?

Hi Steve,

We ran into this recently as well

It used to work fine, I know because some folks here used to test email with gmail servers, but I think gmail now requires tls 1.1 or 1.2 and the bot only has tls 1.0 support. We are looking to update the version of TLS being used for future revisions but that's not something we can get out the door in a few weeks. I have no ETA so the only option I can suggest for now is to use an internal server and if you need to send it to a gmail account, use relaying.

Think I will advise waiting for the update. I did get the following when i was sending from command line which appears to show TLS 1 support --- No client certificate CA names sent Server Temp Key: ECDH, P-256, 256 bits --- SSL handshake has read 3721 bytes and written 331 bytes --- New, TLSv1/SSLv3, Cipher is ECDHE-RSA-RC4-SHA Server public key is 2048 bit Secure Renegotiation IS supported Compression: NONE Expansion: NONE No ALPN negotiated SSL-Session: Protocol : TLSv1 Cipher : ECDHE-RSA-RC4-SHA Session-ID: 9CC545551680BFA8E68E347DAEB79E865E7222C837F3BA13544EC22D70B453F9

Hi Steve,

One of our engineers actually took a NetBotz appliance home to test to make sure that the issue was not firewall related. He stated:

So I was able to get email to gmail to work from my bot, but in my gmail account I had to turn on access to allow for less secure apps for it to work, not good practice!

What he found was this google support doc:

https://support.google.com/accounts/answer/6010255

I still believe we need to address the TLS issue but this may be a viable workaround for you.
