hello again.....

not an ideal solution. i was resistant to
add smtpmail-local-domain after reading
server workarounds.(1) however, the issue is
resolved by adding code given on our mailing
list archive.(2)

* modified .gnus:

(setq gnus-select-method '(nnnil ""))

(add-to-list 'gnus-secondary-select-methods
              '(nnmaildir ""
               (directory "/home/jin/.Maildir/")
               (get-new-mail t)
               (directory-files nnheader-directory-files-safe)))

(setq mail-user-agent 'gnus-user-agent)
(setq read-mail-command 'gnus)

(setq mail-sources
                   '((pop :server "disroot.org"
                          :user "jindam.vani@disroot.org"
                          :password "password")))

(setq message-send-mail-function 'smtpmail-send-it)
(setq smtpmail-default-smtp-server "disroot.org")
(setq smtpmail-local-domain "domain")
(setq smtpmail-sendto-domain "domain")
(setq smtpmail-smtp-server "disroot.org")
(setq smtpmail-smtp-service 587)
(setq smtpmail-auth-credentials '(("disroot.org" 587 
"jindam.vani@disroot.org"
"password")))
(setq smtpmail-starttls-credentials '(("smtp.server" 587 nil nil)))

tried to change hostname given at
linuxhandbook website.(3)

i have modified both /etc/hosts & /etc/hostname,
it was showing same error:

jin@localhost:~$ cat /etc/hostname
jindam.home

jin@localhost:~$ cat /etc/hosts
127.0.0.1       jindam.home

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
