Incorrect DCC checksum generated?
Posted: 22 Nov 2017 10:15
Hello,
I would like to know how you are feeding the received emails to the DCC engine.
I suspect that there is a bug when calculating the DCC BODY checksum in EFA. FUZ1
and FUZ2 checksums are correct.
I have done the following tests:
1) Reviewed the checksums of the DCC request packets sent to a DCC server generated by another product receiving a specific email.
2) Calculated the checksum of the same email transaction including heades using 'dccproc' application on a dcc server: 'cat email.txt | dccproc -QC'.
3) Reviewed the checksums of the DCC request packet sent to DCC server from EFA.
The ALL checksums of 1 and 2 above are identical.
The BODY checksum in 3 is different. The other checksums are correct.
It does not seem to be related to line endings problems when exporting the emails.
Can you investigate this issue?
