sendmail: make it possible to pause after connection helper is started If a non-starttls helper is in use, initial 220 response is processed by us, not by helper. Some servers consider us to be a spammer if we don't wait for it. It is not in protocol, but it is a real-life problem. The workaround in this patch is a magic envvar, $SMTP_ANTISPAM_DELAY: ... -H 'PROG ARGS' Run connection helper. Examples: openssl s_client -quiet -tls1 -starttls smtp -connect smtp.gmail.com:25 openssl s_client -quiet -tls1 -connect smtp.gmail.com:465 $SMTP_ANTISPAM_DELAY: seconds to wait after helper connect ... By using it, people can tweak sendmail behavior even if sendmail invocation is buried in some scripts. function old new delta packed_usage 30464 30497 +33 sendmail_main 1185 1206 +21 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 54/0) Total: 54 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
