i Got the following error:
i Configured a smtp server under IIS 6 as in: http://daniecsp.blogspot.com/2013/04/sp20132010-how-to-configure-incoming.html
When sending a mail from GMail it gets to the drop folder and SharePoint pics up the mail and add it to the list.
When sending a mail from Exchange 2010 client it gets to the drop folder disappears but does not go to the list in sharepoint.
After lots of trouble shooting i eventually intercepted a email(Copy the file before it disappears) from GMail and one from Exchange to compare them.
Open them it in notepad.
In the mail from gmail the x-sender reads: x-sender: email@example.com
In the Exchange Mail it reads(As image below): x-sender: firstname.lastname@example.org
When i edit the x-sender for the exchange mail to be the same as gmail it works..."x-sender: email@example.com"
Ok, now i need to try and figure out why and how to fix it...Hopefully i get a answer before the end of the week...Starting a new job and don't want this one to get the better of me.
If you have the same issue and i don't get a answer maybe this can at least point you in the right direction.
You need to go to your mail enabled list and change the
"Accept E-Mail Messages from any sender"
