OfficePOP

Opinionated ActiveSync to POP bridge for restricted exchange environments.

How

POP Server passes the supplied credentials through to your exchange endpoint. Server is a minimal implementation, may not cover your particular client's commands. Tested using Mutt.

LIST shows unread emails only... not all emails in account

DELE only marks emails as read, no real deletion.

Running

Sets up a localhost bound port :9000 for local use. Simply running python3 main.py is enough to get started.

Requirements

Check requirements.txt for python depends.

Also requires a certificate for the S in POPS, generate a self-signed via...

openssl req -x509 -out localhost.crt -keyout localhost.key \
  -newkey rsa:2048 -nodes -sha256 \
  -subj '/CN=localhost' -extensions EXT -config <( \
   printf "[dn]\nCN=localhost\n[req]\ndistinguished_name = dn\n[EXT]\nsubjectAltName=DNS:localhost\nkeyUsage=digitalSignature\nextendedKeyUsage=serverAuth")

Muttrc

I use the following for my muttrc. Might work for you too.

source "~/.mutt/user"

set pop_user="$my_username@$my_domain"
set pop_pass=$my_password
set pop_checkinterval=60
set pop_reconnect=yes
set pop_host="pops://localhost:9000/"
set timeout=60

set from=$pop_user
set use_from=yes
set realname=$my_realname
set smtp_url="smtp://$pop_user@smtp-mail.outlook.com:587"
set smtp_pass=$pop_pass
