Postmaster filter set customer

[stoicamarcus23]

Hello,
Currently I am using the Postmaster to create tickets from emails.
The email has some lines which represent dynamic fields,but also it has a line that is an email address.
Example:
First Name:xxx;
Last Name:xxx;
......
Email Address:x@x.x

I have two questions:
The postmaster filters accepts a number of limited characters, I have modified the .tt file and now I can input 10000 characters but when I click on submit not all the regex expression is saved.What can I do to fix this?
After the postmaster creates the ticket some notifications are send.I would like to send also a notification that a ticket has been created to the email address from the body of the email.How can I do that?

Thank you very much,
Marcus
