This is a sequel to "Postfix: relay to authenticated SMTP".

I would like to send mail from two different Gmail accounts using Postfix. Here is the relevant section in the Postfix documentation: Configuring Sender-Dependent SASL authentication.

As a concrete example, here's how to set up two Gmail accounts (only relevant sections of the config files are listed below):

/etc/postfix/main.cf:
    # sender-dependent sasl authentication
    smtp_sender_dependent_authentication = yes

sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relay

# There was a day where I have too many color schemes in iTerm2 and I want to remove them all.
# iTerm2 doesn't have "bulk remove" and it was literally painful to delete them one-by-one.

# iTerm2 save it's preference in ~/Library/Preferences/com.googlecode.iterm2.plist in a binary format
# What you need to do is basically copy that somewhere, convert to xml and remove color schemes in the xml files.

$ cd /tmp/
$ cp ~/Library/Preferences/com.googlecode.iterm2.plist .
$ plutil -convert xml1 com.googlecode.iterm2.plist
$ vi com.googlecode.iterm2.plist
