Why is dccproc is ignoring env_from whitelist entries?
DCC checksums are of the entire header line or envelope value. An entry in the whitelist file for jsmith@example.com will have no effect on mail with an envelope value of “J.Smith” jsmith@example.com. The file must contain “J.Smith” jsmith@example.com. Another common cause for this problem is implied by the fact that for an env_from whitelist entry to have any effect, dccproc must be able to find the envelope value in the message in a Return-Path header, an old UNIX-style From_ header, or an -f argument. If your mail delivery agent does not add a Return-Path header and you do not use dccproc -f, then dccproc cannot know about white or blacklist entries for envelope return addresses. Note also that dccproc has no whitelist by default and that dccproc -w must be used.
