This reverts commit c95428f0f1.

add uni.strath.ac.uk

Update UPMC/SU email address configuration

These might need STARTTLS explicitly disabled in the msmtp config file though

A user reports notifications not working on their setup because there is
no display id  contained in the `ps`/`pgrep` output  concerning the Xorg
process.

This commit checks if there's a display server running at all, and if so
it sends notifications even if there's no display id.

Resolves https://github.com/LukeSmithxyz/mutt-wizard/issues/661

Add ucsb.edu to domains.csv

Update domains.csv

Fix notifications on Wayland-based environments

remove old vars like pass_prefix, muttdir
reorder mailbox detection to find inbox case and later delim
offline delim set to _ which should avoid most issues

Fix duplicate mailsync notifications

mailsync: Check for ZDOTDIR when looking for environmental variables inside .zprofile and .zshrc

inside .zprofile and .zshrc.

~/.profile is not necessarily present when using zsh for login and
setting $ZDOTDIR in ~/.zshenv

Fix: `macro index o` overlapping with next account

When the transition is made from an offline profile to an online
profile, there is still someone else's macro - side effects...
Variables, macros, and so on must be taken-into-account
**symmetrically** with any of the `mutt-wizard`'s profiles.
