Added the line:
niser.ac.in,imap.gmail.com,993,smtp.gmail.com,587

Additionally, ceng.metu requires the `domain mailhost.ceng.metu.edu.tr`
option to be added to msmtp config file

when u have multiple emails in neomutt at the same time, you can sometimes forget which email u'r currently viewing, so with this addition youll be able to see.
all i did was add the email to the default status bar configuration
