Actually 2 problems.
Captcha set up.
If I go to an "article" and click on the email icon, fill in the form, email is sent and received as expected. (So email is working)
If I use the "contacts form" fill in the form, which includes a captcha field it "thanks me for the email" but the email is never delivered to the recipient.
I wondered if it might have anything to do with captcha, but have been unable to figure out how to get rid of it in order to eliminate it as a possible cause. Change global config, and disable the captcha plug in, but the form still shows captcha as a requirement, although there is no form field to fill in for it and no captcha display.
A goggle search on Joomla, mail and contact forms shows lots of other people with similar problems.... Mail not working, but could not find a good solution.
Thanks for any help.
