Hi I'm trying a fax server and have it working with zoho mail but is there a way to change the email to fax from using
[SubjectTag],Telephone-number to
Telephone-number @mycompany.com I have a domain just for fax and use catch all so I can receive emails in that format.
Most applications that integrate with email to fax use this format
 
Is there a way? Yes. Has someone posted it? No. Is it complicated? Not at all for someone who knows php it needs some editing in the email_fax file
 
The below is not my code or information, and I have not tested. Test at your own risk.

From unknown IRC posting from unknown date:
the way i have it setup is that it will pull from 1 generic email like catchall@domain.com
then the user sends an email like 3333333333@domain.com and anything in the body will be part of the cover page and any attachment will be sent with the fax
I only have the email account configured on my default domain and then in other domains I have setup authorized senders. I'm using office 365 with a catchall rule for that domain so that any email sent to the domain is forwarded to that email box if it doesnt match another mailbox

then i modified the fax_emails.php so that it uses the updated information and with the fax queue off it's working

set it up and then configure your default domain and add authorized senders.
I also have this in my crontab that triggers it every 2 minutes i think */2 * * * * wget --no-check-certificate --delete-after https://subdomain.domain.com/app/fax/fax_emails.php

seems only to recognize authorized senders from the default domain \I set up a second domain to check a different folder in zoho mail it retrives the email but it does not work because the authorized sender is not in the default domain
 
As I mentioned in original message, I haven't tested this setup.
I would imagine you need to setup a cron job to run with URL of each domain you wan to use
 
I tried that and it ended up to be the solution
Funny I could send from the GUI but not from email so I started to look at the logs and found when you send from the GUI and subscriber not found showed but it used the other domain to send but not email to fax. even though gateway was global had to set outgoing route to global and it worked.
Thank you very much for your help

Do you have email to fax working correctly? I had it set up a few years ago and when I redid my servers, left it off because nobody was using it.
