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.
