I had configured emails server for IMAP and SMTP, Already tested. working well with project management.
Problem is when I create Quotation then I click on 'Send By Email' button to quotation via email.
But it did not send any email to customer email.
* Even 'Opt-Out' and 'Receive Messages by Email' and other options are well set.
I did not figure out what exact problem may be.
Guide me where might be problem so it does not send an email.
