Again most of the info asked in your previous thread is missing:

  • possible errors in the data/owncloud.log (which is btw. also asked in your partly filled template)
  • your mailserver setup

If you don't provide such information its really not possible to help here. Why are you not providing these as asked?

Hi sorry my english is not really well.

No Errors is coming nothin is doing when i send to external user.

my mail configuration is:
mail smtpmode = smtp
mail smptport = 25
mail smtpdebug = false
mail_smtpsecure tls

If nothing is logged in your data/owncloud.log and mails are sent to internal users but not to external users then there is a misconfiguration in your SMTP server not allowing to send out mails to external users.
