Public bug reported:
My provider has a Cisco PIX and want the ehlo command for sending the e-mails
(no way to do it otherwise, he doesn't accepts helo command at all).
Each time I try to use postfix he doesn't work because even if I have
explicitly specified smtp_always_send_ehlo=yes (that means that I want to use
ehlo), postfix ignores it because the router is a PIX.
Now there are about 10 years that I am with this provider and are 10 years that
I patch manually the postfix smpt_proto.c file to avoid this problem and I
never ever had problems with the PIX server, but is annoying that this
"workaround" is still in the code.
It's maybe there for old PIX routers, but it seems that this bug is not present
any more in the last routers (produces in the last 10 years, more or less).
It's time to remove this feature forever or add an option to allow an
user who want to force the ehlo command to do it.
So two possibilities:
1. Remove the SMTP_FEATURE_PIX_NO_ESMTP from the lines where the
session->features are filtered
2. Add a smtp_always_send_ehlo_even_for_PIX=yes option (or something like that)
I'm using an Ubuntu 16.04.1 with postfix 3.1.0
