Hi, am using osticket 1.15.2 version and expecting to trim the thread on view which is created by email source based on Adding ReadMore link to expand previous email history if user/customer reverted using email.

Usually i understand that , previous email history will use below mentioned html tag which needs to suppress for better thread view if user send email with very long history.

  • 'blockquote', // Standard quote block tag
  • 'div.moz-cite-prefix', // Thunderbird
  • 'div.gmail_extra', 'div.gmail_quote', // Gmail

Anybody suggest the way to do this.

Have you tried:
Edit your email template.
Add the Reply Separator Tag to the template before you quote the rest of the thread.
Your Reply Separator Tag is located at Admin panel -> Emails - > Settings
