After the 2.14.4 rollout the test server's mail.log held "discarding EHLO
keywords: ETRN" for every connection on every port: smtpd logs a discard
unless the mask has EHLO_MASK_SILENT (Postfix 3.10.13, src/smtpd/smtpd.c:2016;
src/global/ehlo_mask.c:88 "SILENT-DISCARD"; postconf(5)
smtpd_discard_ehlo_keywords, "Specify the silent-discard pseudo keyword to
prevent this action from being logged"). smtpd_discard_ehlo_keywords is now
silent-discard,etrn; ETRN is still refused (smtpd_etrn_restrictions=reject)
and still not offered.
make e2e (64 passed; checkPostfixHardening reads the value back,
testInboundRelay still sees no ETRN in EHLO and 554) and go vet + go test
(26 packages) on the test server for this tree.
