Dear Basara,
I have tried an gmail account also. I have contacted my hosting and they say that they cannot enable allow_url_fopen function. I have tried with gmail smtp. Herewith, I have enclosed the configuration settings and the error log. I have configured my gmail as a mail client for my servers mail. It is working properly. So I have asked them that if gmail can send a mail from my mail server why can't abantecart. Kindly please tell me where the problem arises what to ask to my hosting provider and how to solve this if they didn't allow fsockopen().
