IMAP Trigger Node Binary File Attachments Corrupted

[darrengoldner]

Bug Description

Beginning around approximately commit 9f87cc2, all binary files retrieved from the IMAP trigger nodes in my workflow are overstated by approximately 2X.

To Reproduce

Create a new IMAP trigger node with credentials to any IMAP mailbox with file attachments.
Test trigger with filter criteria that include a message with attachments.
Compare binary data for attachment(s) vs expectactions

Expected behavior

Binary file attachments should be retrieved exactly as they are represented in the IMAP mailbox.

Hey @darrengoldner,

Are the files actually bigger and corrupted or do we just show a larger size in the UI?

@darrengoldner I have managed to reproduce and have created NODE-1344 as the internal ticket to fix this.
