Cant Send emails

I have email And i downloaded emclient set it up and can recieve but cant send emails what should my setup be, SMTP imap etc… thanks for the help…

did you use the automatic account setup? The recommended IMAP/SMTP settings should be available online on your mail service’s website.
Can you post the SMTP settings of your account here (screenshot will do), to see it go to Tools > Accounts > Your account > SMTP tab.

Thank you,
