Commit eb45c1bd5bd41ec4b62b649db4900f16ce868a19 breaks reading DMARC reports from STDIN

[twesterhever]

On several setups, I (ab?)use /etc/aliases to deliver incoming DMARC reports to the dmarcts-report-parser:

# DMARC Reports
dmarcreports:   "| /etc/postfix/dmarcts-report-parser.pl -e -"

In /etc/postfix/virtual, this destination is defined for mail addresses handling DMARC reports:

# DMARC reports
postmaster+dmarc@example.com					dmarcreports
postmaster+dmarc@example.net					dmarcreports

To the best of my understanding, this setup worked fine until commit eb45c1b, which now causes STDIN not to be a processable file anymore.

Is there another way to continue reading DMARC reports directly from STDIN? If so, I would be happy to be pointed into the right direction. Thank you in advance.

I guess something like changing this line

dmarcts-report-parser/dmarcts-report-parser.pl

Line 423 in 9dd92cf

} elsif (open(FILE, "<", $f)) {

should work, replace

                       } elsif (open(FILE, "<", $f)) {

with

                       } elsif (open(FILE, "<", $f) or (($f eq '-') and (*FILE = *STDIN))) {

This is not tested at all, but fits the "to be pointed into the right direction" I guess. :)
