I will definitely evaluate v3. But our use case doesn't need IMAP. Its not a mail server which many users are going to access from their local mail clients. What we are planning is an email application platform where when an email is received over SMTP, call a web service and store the attachment in another cloud storage.The JAMES server will not relay the emails to any external mail servers. The mail flow ends when it arrives at JAMES. We have an enterprise email server forwarding the emails to this proposed James server. The earlier implementation was using a perl script which was configured through an alias file in SendMail. So essentially the sendmail+perl is going to be replaced with JAMES+Mailets. I have setup Postage and I am going to test the performance with the scenarios. But wanted an expert advice before I start testing them. Do you foresee any issues implementing this using JAMES 2.3.2 ? I know that the performance of the whole flow will depend on the implementation of Mailet. I wanted to know if there are any limitations or constraints etc with the out of the box features of JAMES 2.3.2 considering my use case ?
