A client would like to forward e-mails to us, and have those e-mails and attachments (with allowed file types) associated as notes for specific records in the web application we provide for them.
I'm looking for tools that will take e-mails sent to a specific address and provide our web application with access to the basic data of the email: sender, subject, time stamp, plain text content, html content, attachments, etc. We are flexible in how we can access the data (MS SQL, API, web service, etc).
Our budget is open, and may be expanded if needed, but we are ideally looking for something that is free or has a small one time fee. We may be able to sell something with a small monthly fee ($50 or less?) or a one-time fee of a $1,000 or less. We would prefer something that costs more and works reliably across the many different email formats and encodings, than something cheap that works 90% of the time.
(I'm having trouble finding good options on Google, because I can't seem to find the right terms for searching. E-mail is so widely used that importing searches are focused on end users and parsing searches provide options for parsing specific data fields from emails received.)
