Parse all emails from mail server without chaning state on server

README.txt

# copy getmail config to ~/.getmail/getmailrc

# Create some temporary directories
mkdir -p /tmp/mail/cur
mkdir -p /tmp/mail/tmp
mkdir -p /tmp/mail/new
mkdir /tmp/mail/parsing

# Gather all emails
# They won't be removed from mail server and won't be marked as "read" on server since "peek" used
getmail

# Now move emails you want to different directory:
grep -L -Z -r 'user@needserverfrom.info' /tmp/mail/new | xargs -0 -I{} mv {} /tmp/mail/parsing

# Encoded and multipart emails can be decoded using little Python like:
