"Zoho Mail sends my outgoing emails with From:
me@mycompany.com [ this is GOOD ], and
Sender:
me@zoho.com - this is NOT so good.
Many email clients ignore Sender header, but some, most notably MS Outlook and Hotmail use it to construct "From" field along the lines of:
"Sent by
me@zoho.com on behalf of
me@mycompany.com"
This is confusing and unprofessional. I cannot possibly move my colleagues to Zoho until their emails look like they come from them directly."
