I have a website where mails are sent. Those mails from website (contact mail, booking mail) are being sent well. But when I go to shell with ssh and give
sendmail [email protected] it is not sending.
the error log in
did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
some time ago, i had a problem with permission, i changed without knowing the permission of
/etc/ folder, then later i did
chmod 755 /etc/ then everything seemed to work properly. but now, i am getting this error.
server os is openSuse.
what can I do?
