I'm using Mandrill to send E-Mails in my PHP Project and integrated it via the API. So far so good E-Mails go out and arrive their recipient, but something bothers me about the missing SPF and DKIM entries.
When the E-Mails are opened in outlook the "on behalf of" issue occurs (FAQ from mandrills KB). But I can't fix this, since too many of our customers do not have the necessary skills/ access-rights to create a SPF entry for their domain, so we learned to live with that.
We verified our own domain at mandrill to use it as custom sending-domain to get rid of the
from: reallyLongString@mandrillapp.com on behalf of customerName@customerDomain.com
and exchange it with
from: mailbot@ourDomain.com on behalf of customerName@customerDomain.com
but somehow I can't get this to work!
I cannot find an option to set "mailbot" as sender. Even worse, Mandrill makes up a phantasy e-mail-address consisting of customerName@ourDomain.com. If some customer gets the idea to send to this address we've got a disaster upcoming. Also the API does not specify anything like that in the "Messages"-Section.
How can I configure mandrill to send E-Mails with a from-field appearing in outlook like this:
mailbot@ourDomain.com on behalf of customerName@customerDomain.com
? Really cannot find anything in the docs or the web. Thanks in advance!
