bug: Neomutt with home-manager: No mailing lists found

Issue description

I was trying to setup neomutt declaratively with nix home-manager to manage my gmail. I tried a bunch of guides online, a bunch of dotfiles, but all seems to be fruitless.

What works:

1. I can send emails and receive email headers from neomutt.
2. I can go through all Inbox email headers.

Issues:

1. The email headers seem to load just fine, however I cannot get the body -
   when I press on the email header, it says 'No mailing lists found'.
2. Only Inbox is there - the sidebar doesn't show Sent/Trash/Drafts/etc.
3. Have been trying to also set up my University mailbox
   (they have Thunderbird instructions). It's not gmail-based.
   When I try syncing it with mbsync, I get:

Socket error: secure connect to <mail_server> (<mail_ip>:993): error:0A00018A:SSL routines::dh key too small

Here is my neomutt.nix:

  # Partially based on https://github.com/Baitinq/nixos-config/blob/c9851e910f6e0dc574527e2da4be29d704eda27d/modules/email/default.nix
  accounts.email= {
	maildirBasePath = "Maildir";
    accounts.gmail = {

	  address = gmailname;
	  userName = gmailname;

	  msmtp.enable = true;
	  mbsync = { 
	    enable = true;
	    create = "maildir";
	  };

	  folders = {
	    inbox = "Inbox";
	    sent = "\[Gmail\]/Sent\\ Mail";
	    trash = "\[Gmail\]/Trash";
	    drafts = "\[Gmail\]/Drafts";
	    #spam = "[Gmail]/Spam";
	  };

          set charset = UTF-8     # value of $LANG; also fallback for send_charset

          set use_from = yes

      };
	  primary = true;
	  realName = realname;

	  #imap = {
      #  host = "imap.gmail.com";
      #  port = 993;
      #};

      #smtp = {
      #  host = "smtp.gmail.com";
      #  port = 587;
      #};

	  imapnotify = {
        enable = true;
        boxes = [ "Inbox" ];
        onNotifyPost = ''
          ${pkgs.libnotify}/bin/notify-send "New mail arrived."
        '';
      };

	  signature.text = signature;
	  signature.showSignature = "append";
	  passwordCommand = pass_cmd;
	  flavor = "gmail.com"; # flavor sorta works, while individual imap/smtp setup doesn't
	  #maildir.path = "gmail";
	};
  };

  services = {
    mbsync.enable = true;
    imapnotify.enable = true;
  };
  programs = {
    neomutt = {
      enable = true;
      vimKeys = true;
      sidebar.enable = true;
      sort = "reverse-date";
    };
    mbsync.enable = true;
    msmtp.enable = true;
  };
  home.packages = with pkgs; [ openssl ];
  #programs.notmuch = {
  #  enable = true;
  #};
}

Just a few things I have tried (some commented out):

• imap/smtp setup manually instead of using flavor option
  (refused to even load the email headers. Flavor at least loads the headers)
• Setting gmail directories in folders option or neomutt.extraMailboxes
• Changing directory that stores emails on disk
• Tryin combinations of "imap"/"maildir"/"both" in mbsync.create
  and/or neomutt.mailboxType
• Using/not using mbsync and/or notmuch
• Not using imapnotify (wasn't in my original configuration,
  before I found cited github config)
• Hard-coding things into extraConfig, going without it, etc.

The way I call variables like 'pass_cmd' might be wrong,
but that's not actually what I'm doing in the actual file,
just replaced them for privacy reasons here.
Variables are definitely not the issue.

Please help, I tried fixing this error for a few days,
and cannot find anything even remotely useful online that improves my situation.
Even if you can give me a direction where I can go to, that would be amazing.
Thank you!
