help changing the From address when sending email

[Theresa Pettit]

I'm very new to this so maybe I'm oversimplifying it in my head. Do I really need to go through all of those steps? I do have a domain I purchased but it's not being hosted anywhere at the moment. 

Is it possible somehow just have my domain connected to my on-rev server account and then direct it to that to use as the from address or is it more complicated requiring the extra steps below?

Thanks,
Theresa

I thought sending email was an easy thing. It turns out in this spam/virus
world we live it gets more complicated.

First of all sending messages with a "from" other than your on-rev master
address is technically "spoofing". This is done legitimately all the time
with consultants running a server process on behalf of their customers.
There are several things one can do to prevent spam filters from having
heart failure.

1) Put a "mailfrom:ACCOUNTNAME at SERVERNAME.on-rev.com" in the email header.
This give spam filters a valid path back to the on-rev server.
ACCOUNTNAME = master on-rev email address(login username)
SERVERNAME = Server name (i.e. diesel, thor....)

2) Put a "from:SPOOFEDADDRESS at SOMECOMPANY.com" in the email header.
SPOOFEDADDRESS at SOMECOMPANY.com = is the email address you want the recipient
to see. It should be a valid email.

3) put a "Message-Id: <UNIQUE-ID at SOMECOMPANY.com>" in the email header.
UNIQUE-ID = I use the LC uuid

4) put a "Date: Wed, 7 Oct 2015 22:48:57 +0200" in the email header. LC
Example: ("Date:" && the internet date)

5) put a "Subject: MY SUBJECT" in the email header.

5) If the email is html then also include a text version also. Not including
a text version will up your spam score.

6) A short email body will up your spam score.

7) Non https images or links will up your spam score.

8) add a spf txt record to your DNS. This is not a show stopper. See
https://www.digitalocean.com/community/tutorials/how-to-use-an-spf-record-to
-prevent-spoofing-improve-e-mail-reliability for example. I am not vouching
for this site it's just an example. Do a "spf txt record examples" search
for more information.

There are on-line tools to test your spam score. Paste in the
email(including headers) and see your score.

Before I did all this my X-AntiAbuse spam score was 12 out of 10. All my
email was flagged as spam. By doing the above steps (sans the spf thingy) I
lowered it to -0.3

I am not an email expert and I'm sure this score could be lowered even more
with more header tweaking but this get my emails delivered and not put into
junk mail folders.

I have done some major re-working of the example sendmail script. Let me
know if you would like me to send you my updated version. You may have to
change a few things to make it your own.

I'm creating an app that needs to send an email to the user. I've gone
through the lesson about sending email through LiveCode Server here
http://lessons.runrev.com/m/4070/l/8184-sending-emails-from-livecode-server-
scripts
and I get the email to send but no matter what I seem to do, I can't get the
"from" address to be anything but my server account email. Is there
something I'm missing? I've tried it using a variable and also just putting
a straight email address in but I can't get it to change.
