# The plugin stopped dead

 * [6 years, 10 months ago](https://wordpress.org/support/topic/the-plugin-stopped-dead/)
 * This plugin was quite complex to set up but I finally got it working. Using SSL
   on SMTP Port 465 with a G Suite account. Set it up identically on a second domain
   for development purposes using the same G Suite account & email & OAUTH codes
   and it too worked great. Then as I got down to testing emails sent I decided 
   I wanted to use a ‘noreply’ email on the same domain for initial emails anyway,
   to dodge spammers. G Suite support helped me set that up and it worked fine: 
   I could send emails from noreply but any email sent to it was bounced back, exactly
   as it should work. But when I changed the From email address to the noreply in
   the plugin’s setup, it wouldn’t work. So I thought maybe it had to match with
   the OAuth Email Address setting and changed that too but it didn’t work in that
   case either. So I put it back the way it was with the original email address 
   in both those fields, but it STILL didn’t work! And the identical setup on the
   other domain, which I hadn’t touched, also didn’t work anymore.
 * So I called G Suite support thinking maybe I had triggered some kind of flag 
   in Gmail somehow maybe by changing the email address that made it stop accepting
   my emails, but the support guy said there wasn’t any such flag. He gave me a 
   URL where I could try disabling Gmail’s ReCaptcha nuisance, but that didn’t make
   any difference either. I can still send and receive emails through the Gmail 
   account on my old Blackberry so it doesn’t seem to be a Gmail problem really,
   and the Support guy eventually told me we were outside the scope of his job and
   that I should get a WordPress developer to work on it.
 * This is my ‘Server Info’ from the plugin’s option for that:
    OS: Linux us-imm-
   web136.main-hosting.eu 3.10.0-962.3.2.lve1.5.25.6.el7.x86_64 #1 SMP Thu Apr 18

 * WHY did I wait almost four days for help that never came? I set up the ‘WP Mail
   SMTP’ plugin in just a couple minutes and it worked right away! Problem solved!

 * yep, same problem here, stopped working after years of it working with the same
   error.. I guess given that the plugin is free we can’t expect the world in terms
   of support but I’m glad there is an alternative plugin to switch to
