WTF, git

Dear Lazyweb, why is git so fucking slow?

I don't actually expect anyone to be able answer this, but I need to scream into the void anyway.

I changed 2 lines in a 5 KB file and it took 20 seconds.

Dear Lazyweb,

How do I prevent postfix forgeries in "From:" rather than envelope?

Putting "dnalounge.com REJECT Forgery" in "sender_access" prevents inbound unauthenticated SMTP connections from forging my domain in the envelope, but doesn't reject messages like:

Return-Path: spammer@example.com
From: example@dnalounge.com
or
Return-Path: spammer@example.com
From: "example@dnalounge.com" <spammer@example.com>

Looking for a postfix solution, not a spamassassin solution.

Current settings:

smtpd_helo_restrictions =
        permit_mynetworks,
        reject_non_fqdn_helo_hostname,
        reject_invalid_helo_hostname,
        permit

smtpd_sender_restrictions =
        permit_mynetworks,
        reject_non_fqdn_sender,
        reject_unknown_sender_domain,
        permit

smtpd_recipient_restrictions =
        reject_unauth_pipelining,
        reject_non_fqdn_recipient,
        reject_unknown_recipient_domain,
        permit_mynetworks,
        permit_sasl_authenticated,
        reject_unauth_destination,
        check_recipient_access hash:/etc/postfix/access,
        check_sender_access hash:/etc/postfix/sender_access,
        reject_rbl_client zen.spamhaus.org,
        permit

smtpd_relay_restrictions =
        permit_mynetworks,
        permit_sasl_authenticated,
        reject_unauth_destination


Update: I have still not gotten an answer to this question that I understand or believe. Is the person below who said "you can only solve this by adding even more nonstandard complexity to master.cf" correct?
