Title: Manrill Stopped Working Last modified: August 30, 2016 --- # Manrill Stopped Working * Resolved [Bryan Rainey](https://wordpress.org/support/users/bryanrainey/) * (@bryanrainey) * [10 years, 9 months ago](https://wordpress.org/support/topic/manrill-stopped-working/) * I love Postman SMTP and have had no issues. Everything has worked great for months until 3 days ago. * All emails have stopped and the logs show “535 Incorrect authentication data”. * Have you heard of this and do you have any thoughts? * [https://wordpress.org/plugins/postman-smtp/](https://wordpress.org/plugins/postman-smtp/) Viewing 7 replies - 1 through 7 (of 7 total) * Plugin Author [Jason Hendriks](https://wordpress.org/support/users/jasonhendriks/) * (@jasonhendriks) * [10 years, 9 months ago](https://wordpress.org/support/topic/manrill-stopped-working/#post-6694622) * Incorrect authentication data means your name + password are being rejected by the email server you are connecting to. * Either your account has expired, your password has expired or changed, or you are no longer connecting to Mandrill. * Thread Starter [Bryan Rainey](https://wordpress.org/support/users/bryanrainey/) * (@bryanrainey) * [10 years, 9 months ago](https://wordpress.org/support/topic/manrill-stopped-working/#post-6694638) * Thanks for the response, Jason. * I’ve contacted BlueHost, they say I’m not being block and all looks good. I’ve logged in to Mandrill and verified account active, reputation “excellent”, user name and password were copied and pasted into Postman. * Really strange. All of a sudden everything just quite working. * Plugin Author [Jason Hendriks](https://wordpress.org/support/users/jasonhendriks/) * (@jasonhendriks) * [10 years, 9 months ago](https://wordpress.org/support/topic/manrill-stopped-working/#post-6694659) * Bluehost? * > I’ve contacted BlueHost, they say I’m not being block and all looks good. * Quite unlikely. AFAIK – and trust me, at this point I’m quite the authority –;-), Bluehost blocks **all** access to external SMTP servers. Bluehost and GoDaddy were the reason I wrote the [Web Services version of Postman for Gmail users](https://wordpress.org/plugins/postman-gmail-extension/). * Please post the results of Postman’s Connectivity Test to Mandril. * Don’t worry, we can still it get to work 🙂 * Thread Starter [Bryan Rainey](https://wordpress.org/support/users/bryanrainey/) * (@bryanrainey) * [10 years, 9 months ago](https://wordpress.org/support/topic/manrill-stopped-working/#post-6694683) * I appreciate that, Jason. It’s just weird I’ve been using Bluehost for over year and Postman with Mandrill for over 4 months and on Friday it all quit working. * I was able to get Gmail API working with Postman. From what I can tell the GMail API has a limit of 100 messages.send per day which could be a problem. * Below is the diagnosis test when using Mandrill: OS: Linux server.validbrands. com 2.6.32-573.3.1.el6.x86_64 #1 SMP Thu Aug 13 22:55:16 UTC 2015 x86_64 HTTP User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:41.0) Gecko/20100101 Firefox/ 41.0 PHP: Linux 5.4.28 C PHP Dependencies: iconv=Yes, spl_autoload=Yes, openssl =Yes, sockets=Yes, allow_url_fopen=Yes, mcrypt=Yes WordPress: 4.3.1 en_US WordPress Theme: ValidBrands Apollo WordPress Plugins: ManageWP – Worker, Gravity Forms, Admin Columns Pro, Bean Tweets, Better Font Awesome, CRED Frontend Editor, Disable Comments, Disable Emojis, FacetWP – Cache, FacetWP, Font Awesome 4 Menus, Genesis 404, Genesis Layout Extras, Genesis Simple Edits, Genesis Simple Hooks, Google Analytics Track Outbound Links, Google XML Sitemaps, Gravity Forms Duplicate Prevention, Gravity Forms Sticky List, Gravity Forms Coupons Add-On, Gravity Forms MailChimp Add-On, Gravity Forms PayPal Standard Add-On, Gravity Forms Stripe Add-On, Gravity Forms User Registration Add-On, Heartbeat Control, Maintenance Mode, Page Links To, Postman SMTP, Q and A Focus Plus FAQ, Really Simple CSV Importer, Rename wp-login.php (unmaintained), SearchWP LIKE Terms, SearchWP, Shortcodes Ultimate: Extra Shortcodes, Shortcodes Ultimate: Additional Skins, Shortcodes Ultimate, Simple Share Buttons Adder, SumoMe, Access, Types, Visualizer: Charts and Graphs, User Bookmarks for WordPress, WP CSV, WP Views WordPress wp_mail Filter(s): Postman: 1.6.24 Postman Sender Domain (Envelope|Message): validbrands. com | validbrands.com Postman Prevent Message Sender Override (Email|Name): No | No Postman Transport URI: smtp:tls:plain://smtp.mandrillapp.com:587 Postman Transport Status (Configured|Ready|Connected): Yes | Yes | Yes Postman Deliveries( Success|Fail): 445 | 12 * Plugin Author [Jason Hendriks](https://wordpress.org/support/users/jasonhendriks/) * (@jasonhendriks) * [10 years, 9 months ago](https://wordpress.org/support/topic/manrill-stopped-working/#post-6694684) * That’s the Diagnostic Test, not the Connectivity Test. But if you were able to get the Gmail API to work, then you should also be able to get the Mandrill API to work. * Please download the Postman 1.7 beta, and switch to the Mandrill API.
