Error: MAIL FROM not accepted from server

Hi,

I am really struggling to fix an issue with my site and hoping someone can please help!! Basically, all functionality which involves an email being sent from the server is not working on my website.

This has previously worked, then started having intermittent issues, and now i get constant problems. The issue...

Any function that requires an email being sent from the site is making the website go to a blank white page and then giving the following error in the admin error logs:

PHP Notice: Error: MAIL FROM not accepted from server! in /home/content/65/11980265/html/system/library/mail.php on line 290

Litrally my error logs in the admin site is full of the same error every day! It means that registering for an account, creating an order as a new customer (registering for an account), Contact Us all arn't working at all. Also if a user checksout as a guess then no confirmation emails are sent to the customer or me the admin to say an order has been placed.

I would really appreciate some help on this as it is starting to cost me customers. Thank you anyone in advance who can offer some help and support. My website is iconcardsandgifts.com if you would like to try registering for an account or using the contact us to see the issue happening.

I am using OpenCart v1.5.5.1 and i first started noticing the errors when trying to add couple of different extensions that allowed you to send pictures of products with the order confirmations, this has now been removed but im not sure if it has left something over that has broke it still.

check the below line, possibly, the server does not accept >>> base64_encode($this->sender) <<<
