Hey just a tip, when posting the main.cf file -- it might be easier for readability purposes to cut out all the commented lines: I usually do something like
cat main.cf | grep -v ^# | grep -v ^$

smtp_sasl_password_maps = hash:/usr/local/etc/postfix/sasl_passwd

You sure you have a file located in this directory?

I purged postfix and then reinstalled postfix. I then chose "No Configuration". When I try to send an email now I get this message: https://imgur.com/a/ipDls1B


Here is what the main.cf.proto file looks like: https://imgur.com/a/wNYXpkI

Ok I just set this up on a new Ubuntu Server and can confirm it will work -- or it did for me at least.
I followed the instructions here:
https://www.linode.com/docs/email/po...ian-or-ubuntu/

I wanted port 465 and not 587 as I've stated earlier so I made the following modifications
/etc/postfix/sasl/sasl_passwd

smtp.gmail.com <your_gmail_username>:<your gmail app specific password>

I put the following at the bottom of my main.cf file:

# Manual Configuation for Gmail
## SASL Options
smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/sasl/sasl_passwd

## TLS Options
smtp_use_tls = yes
smtp_tls_security_level = encrypt
##Following line required for port 465
smtp_tls_wrappermode = yes
tls_random_source = dev:/dev/urandom

## Relay host
relayhost = [smtp.gmail.com]:465

disable_vrfy_command = yes

Hopefully that helps -- Admittedly I've set this up before, however this process took me all of 5 minutes. It took me longer to construct this post than setup the mail server.

I am unable to send an email. I still get this message: https://imgur.com/a/ipDls1B

I refer you back to post 12 in this thread again - your test emails could be bouncing.

The log entries in post25 tell me that at least some of your test messages are not getting to where they should:

[rjphares]

Do you know what I typed that could have produced those error message? Since I deleted postfix and reinstalled with "No Configuration" I have been unable to find a mail.log file.

[kevdog]

I think you need to install with internet configuration. See this post about log files for mail/postfix: https://askubuntu.com/questions/3947...tfix-log-files

[rjphares]

I am not sure the configuration is correct but this is the output : https://imgur.com/a/g5s5fJB

[kevdog]

Yikes - the postfix daemon isn't even running -- I'm not sure why. Something is screwed up with your postfix installation.

[rjphares]

Success. I changed my hostname to DESKTOP-K50P15B. Really excited to have solved this issue and couldn't have done it with out all the advice.
