Order Confirmation email showing 'on behalf of'

Hi
I have a problem whereby our customer's order confirmation email "From" field now shows "my_server_name@my_host.com; on behalf of; My_Business_Name [contact@my_site.com]" whereas a couple of days ago, the "From" field just showed :" My_Business_Name [contact@my_site.com]"

I checked with my host, and they reported as follows: " *Nothing has changed on the server recently either as far as packages such as PHP, the Web Server etc are concerned. It appears that ZenCart's PHPMailer is adding this to the email headers:

Sender: "*

This new display only started on Saturday; no changes/alterations/upgrades were made to my zencart configuration.

Does ZenCart insert the "Sender" in the email headers and if so, how can that email address be changed?


Many thanks & hoping that someone has some advice for me

It's interesting that I don't find any of these variables in a standard Zen install or its database.

Could you hit reply and answer the posting tips?

• What version of Zen Cart are you using? 1.38a

• Has your site been upgraded? When? From what version(s)? no

• What addons have you installed? When?** no add ons since or just prior to Saturday.**

• If you're encountering problems that could be related to your server or hosting company, include the name of your hosting company (not their URL). Digital Pacific (Australia)

• WHEN did the problem "start"? How does that compare with other events of your hosting company, changes you've made to your site files/addons, or your admin settings, etc? Saturday, 26 June. (please see my host's response previous post)

• If this is your first store, have you tested all aspects of transactions before going live? store has been operational for a couple of years

If it worked before and things are now different and you didn't change anything then that only leaves the hosting ... Yell at them some more?

What addons have you installed? When?** no add ons since or just prior to Saturday.**So.... We can rule out ANY mods that might involve email?
