can I modify email address field format?

[dianis123]

Hello,

when I going to open a TT, I want to send it to many email addresses selecting an only customer, i'm doing it writting in the client email field: email1@sample1.com;email2@sample2.com;email3@sample3.com. in this form, when I select the customer, the ticket is sent to all email addresses.
but, when I want to reply all in microsoft outlook, we need that the email addresses are separated by an space: email1@sample1.com; email2@sample2.com; email3@sample3.com. can I modify in OTRS the format to send the tickets adding an space between the email addresses?

thanks in advance...
