> Add processor to GetEmail supporting IMAP and POP3
> --------------------------------------------------
>
> Key: NIFI-1148
> URL: https://issues.apache.org/jira/browse/NIFI-1148
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Extensions
> Reporter: Joseph Witt
> Assignee: Oleg Zhurakousky
> Fix For: 1.0.0
>
>
> It is fairly common that users want to be able to acquire data via email.
> This means both IMAP and POP3. POP3 is easier as it is a sort of fire/forget
> model whereas IMAP involves more state handling. But in any event both modes
> are important to support.
