I have 20 or so email notifications. I have some older ones that are received by my computer with an address like this:

From Me <mymail address

Subject  ISY Test

To Me <mymail address..

With the email setting like this:

Custom Notification 'Garage Notice' [1]

From  blank

Subject Garage Alert

Body    Garage Door is OPEN !!!

I also have one I just created with the following...

From blank

Subject  Arrival Set  - ${sys.program.#.name}

Body   Testing New Arrival Set

My email receives this like this:

My email list shows

Subject  Arrival - Set - ArrivalDepeartureSet        With the Correspondents    myemail.domainname

The older one from above  Subject  ISY Test     With the Correspondents      ISY MYHOUSE

 

My email server settings on ISY are:

SMTP Server    myisp smtp.server.com

User ID  myemail address

From*   ISY MYHOME:myemailaddress

So what is going on..  the same settings for both emails with different from receipts.

My email program has filters set to store my ISY notifications in an ISY folder...  otherwise this isn't an issue.. 

I just can't see why it works differently for email notifications all using the same email settings.

you have the From Field set correctly... many people miss that colon in the example.

SMTP Server    myisp smtp.server.com

this doesn't look correct... but if you're receiving emails apparently it is correct... the field should just have smtp.server.com

My understanding of your issue after reading the post multiple times is that you are having issues with the FROM address?

Perhaps you could restate exactly what the issue is, because it's very hard to follow from your initial post.

I have an email notification that I created early on that is sent to my email address that works fine.

My email shows this in the displayed header " what I see when looking at a list of new emails" (not the source code info)  like this;

Subject                                                 Correspondents                                    Date

Garage Alert                                         ISY MYHOUSE                                      01/04/2022,  2:42 PM

While an email notification that I just created is displayed like this:

Arrival Set                                           jim@mydomain                                       01/04/2022,   3:40 PM

 

My email settings on ISY are the same settings for all emails.

My Subject lines are blank in each separate customized notification message:

I have tried using  ISY MYHOME:name@mydomain.com   in the subject line of the customization as well..

This one has me baffled ...

Unless your curious don't spend any more time on this.. as I have created an email forward address

ISY@mydomain.com   so now my email will filter my email properly now...

Thanks for the look see...   I can't see why it is different based on either the number of custom emails I have or simply the time frame of when I created them...  maybe something change after v4 ? 

 

From the ISY's perspective, there's only two places From can come from:

The smtp client defaults as shown above,

and that can be override in an individual message.  In the case shown above the From is blank, meaning use default.  Note that when this field is used it's the same format as the default with Name and email address separated by a colon.

Now once it leaves the ISY and is accepted by the smtp server the smtp server could also be replacing a blank or corrupt FROM line. and likewise the email client thats receiving the email message could also be replacing a blank or corrupt FROM line, and likewise most mail clients allow filters to change the FROM line.  If I was betting tho, it's more than likely the email server providing a default FROM.
