SMTP not working after upgrade to 11.2.6

Was using xsibackup free version 11.0.1 and needed to upgrade as I ran into a bug where backups were failing to fire off, after I installed the latest ESXi patch.  Was doing (line 490: syntax error: unexpected "&") and not backing up anything.

Upgraded to 11.2.6 and now I can't get SMTP to work with Gmail at all. I've tried installing on two different ESXi boxes and they are both doing the same thing.  I have it configured the same way as 11.0.1 was.

Running  ./xsibackup --check-smtp=username@gmail.com --use-smtp=2
and here are the results:

Using stored SMTP server info...
Found conf/smtpsrvs file...
Using SMTP server #2: smtp.gmail.com:465
Open firewall: 2019-07-21T22:22:08|  Opening port 465 for SMTPout-465 service...
USING KEY: xsibackup_id_rsa
Firewall rule SMTPout-465 closed.
Killed


Not much for me to go on..  Any ideas?  Any way to turn on more detailed debug logging or am I testing incorrectly?

Re: SMTP not working after upgrade to 11.2.6

[root@ESXiR420:/vmfs/volumes/5be9760a-8ba90cd5-3a4e-000af77eadb8/xsi-dir] esxcli network firewall set --enabled false
[root@ESXiR420:/vmfs/volumes/5be9760a-8ba90cd5-3a4e-000af77eadb8/xsi-dir] nc -4z smtp.gmail.com 465

Connection to smtp.gmail.com 465 port [tcp/smtps] succeeded!

Netcat doesn't seem to have an issue reaching smtp.gmail.com either.

Re: SMTP not working after upgrade to 11.2.6

There have been some changes in OpenSSL lately and this affects the way keys are exchanged with e-mail servers. We have addressed this in latest versions and it is working with GMail for us and other clients. Please, contact suppport to receive personalized support, it is included for Pro users.

Re: SMTP not working after upgrade to 11.2.6

So what you're telling me is that the free version (11.2.6) is broken with Gmail and this is a known issue?
When will the free version fix be implemented?

Re: SMTP not working after upgrade to 11.2.6

Latest versions of XSIBackup-Free incorporate those improvements as well, this is the full output of a test we just made using a GMail account

Re: SMTP not working after upgrade to 11.2.6

Out of curiosity, what version of ESXi is that from?

I'm on version 6.5.0 Update 3 (Build 13932383) on both servers and both are doing the exact same thing.  No error message nor output to indicate an issue.

Re: SMTP not working after upgrade to 11.2.6

As a test, I copied the following files from my previous installation to the new one:

xsibackup_id_rsa.pub
xsibackup_id_rsa.pem
xsibackup_id_rsa
request.key

I noticed that the previous keys were in RSA format vs OPENSSH.

And now it will sucessfully send email.  Not sure if that request.key has anything to do with things..

Re: SMTP not working after upgrade to 11.2.6

All XSIBackup keys are RSA, they have not changed since long ago when they use to be DSA. We don't know what you mean by OPENSSH format.

Re: SMTP not working after upgrade to 11.2.6

The new xsibackup_id_rsa file headers look like this:

-----BEGIN OPENSSH PRIVATE KEY-----

Key goes here

-----END OPENSSH PRIVATE KEY-----



The old one looks like this:

-----BEGIN RSA PRIVATE KEY-----

Key

-----END RSA PRIVATE KEY-----

Re: SMTP not working after upgrade to 11.2.6

Those are just comments, they should not affect functioning. We'll take a look at this part and eventually publish any relevant information.
