fdm

After trying a few different CLI mail clients---mutt/neomutt, s-nail, etc.---I've come to love the approach of mblaze[0], _i.e._ just a collection of commands to interact with maildirs, which can be separately managed by OfflineIMAP or whatever. I'm curious how mblaze+offlineimap compares to other similar setups: nmh[1], fdm[2], and getmail.

POP3 is still useful. I have many addresses for various needs and don't need to store email on servers for almost all of them (mostly because it costs money). There is at least one IMAP client* that supports fetching mail (not syncing like most of them do), but POP3 has much wider selection of clients and serves that need perfectly. *: https://github.com/nicm/fdm

It may not be helpful in your particular case depending on how your Slack is administered and similar, but my setup is like so: - https://github.com/wee-slack/wee-slack with WeeChat (weechat.org) for IM only (i.e. configured so that it only notifies when an IM (one-on-one or group) is received); and - https://github.com/tomhrr/paws for retrieving messages from Slack as email, and sending responses to those emails to Slack. https://github.com/nicm/fdm is used for all filtering of email, including Slack messages. This allows for rules like e.g. marking everything from Slack as read, unless it's from channel X and matches your username, or it was sent after 6pm, or similar. With this setup, IMs still come through as IMs, but everything else goes to email and is treated like email. Retrieving email and Slack messages happens based on local

If you're looking for something like fetchmail, I find fdm to be superior in just about every way: https://github.com/nicm/fdm
