SOLVED - How to set up Email with System Admin pro but no FQDN?

I am running the ISO on a virtual machine, based on CentOs I believe. I purchased the system admin module but have not been able to get email working. I’m trying to get it to work with gmail. I created the app and got the 16 digit password. I followed several guides setting up the and sasl_passwd file but keep getting “SASL authentication failed; server[] said: 535-5.7.8 Username and Password not accepted.” I am stuck what to try next. Had to edit post as it is seeing my information as links so am not able to post

sasl files has " mygamilemail:16digitapppaswordfromgooglenospaces

If you mark up text as pre-formatted, it won’t be scanned for links.

There is a preference for using for non-trivial file extracts.

queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
mail_owner = postfix
inet_interfaces = localhost
inet_protocols = all
mydestination = $myhostname, localhost.$mydomain, localhost
unknown_local_recipient_reject_code = 550
smtp_tls_security_level = secure
smtp_tls_mandatory_protocols = TLSv1
smtp_tls_mandatory_ciphers = high
smtp_tls_secure_cert_match = nexthop
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
debug_peer_level = 2
debugger_command =
         ddd $daemon_directory/$process_name $process_id & sleep 5
sendmail_path = /usr/sbin/sendmail.postfix
newaliases_path = /usr/bin/newaliases.postfix
mailq_path = /usr/bin/mailq.postfix
setgid_group = postdrop
html_directory = no
manpage_directory = /usr/share/man
sample_directory = /usr/share/doc/postfix-2.10.1/samples
readme_directory = /usr/share/doc/postfix-2.10.1/README_FILES
smtp_generic_maps = hash:/etc/postfix/generic
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_sasl_type = cyrus
smtp_use_tls = yes
smtp_tls_CAfile = /etc/pki/tls/certs/ca-bundle.crt
relayhost =
myhostname =

Some things I have noticed different from the different guides/posts: Some enclose the relay host in [ ] and some don’t? Ubunu and CentOs seem to keep the CAfile in different locations (I did edit the path to where I verified the file to be) There are different methods and commands to send email from the command line… tried all I could find but no success. I was not able to find a command line example where I could also enter the google 16 digit password… was hoping to verify it was not a google end problem.

Square brackets means don’t use a DNS MX record, but treat the address as literally the server to use.

Is one way better than the other?

Solved - not sure exactly which change I made made it work, or if it was more about rebooting at the right time. If it was due to a change, I did change the inet_protocalls = all to ipv4 in the file. I also suspect fwconsole stop …and then fwconsole start are more effective than fwconsole reload. I got clues on the stop and start that I did not get with just reload. I found several posts but few solutions when searching this problem, hope this helps someone.
