Hi all, I set up Mautic on my server, do the CRON jobs and all but, when I want to send an email, it doesnt work. I use Sendgrid services to send it and when I want to connect it’s show me this error (pass and Id are well registred): Unable to connect with TLS encryption Log data: ++ Starting MauticEmailBundleSwiftmailerTransportSendgridTransport \<\< [220-server.graditest.com](http://220-server.graditest.com) ESMTP Exim 4.86 #2 Fri, 20 Nov 2015 03:31:58 +0000 220-We do not authorize the use of this system to transport unsolicited, 220 and/or bulk e-mail. \>\> EHLO [marketing.graditest.com](http://marketing.graditest.com) \<\< [250-server.graditest.com](http://250-server.graditest.com) Hello [server.graditest.com](http://server.graditest.com) [162.144.202.98] 250-SIZE 52428800 250-8BITMIME 250-PIPELINING 250-AUTH PLAIN LOGIN 250-STARTTLS 250 HELP \>\> STARTTLS \<\< 220 TLS go ahead !!

The error message says: > [@](#): > > Unable to connect with TLS encryption Try a different encryption or a port number. ---

Hi escopecz, Thanks to always reply 🙂 can you be a bit more specific, I’m learning and sometimes can be a bit difficult to me. Ok, I need to change TLS, should it be: 1. from Mautic? 2. from my server? 3. from sendgrid? On Mautic, I just have option to change “Service to send mail through”. As I saw in another post where someone have a problem with sendgrid, i try to use “Other SMTP Server” with this config: SMTP host : [smtp.sendgrid.net](http://smtp.sendgrid.net) SMTP port : 465 SMTP encryption type : SSL / TLS / None (I tried all) SMTP authentication mode : Login and set my Sendgrid password and username. But it’s not working too. Something from Sendgrid I dind’t configurate well? Can it be from my server side? Thx Loic ---

I’m no expert for email configuration. All I have is [google search](https://www.google.cz/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8&client=ubuntu#q=sendgrid%20smtp). From the [Sendgrid docs](https://sendgrid.com/docs/Integrate/index.html?ls=Advertisement&cid=70180000000cl5Z&lsd=adwords&kw=Sendgrid%20smtp&mt=e&gaid=Integration_Sitelink&mc=Paid%20Search&mcd=AdWords&keyword=sendgrid%20smtp&network=g&matchtype=e&mobile=&content=&search=1&cvosrc=PPC.Google.sendgrid%20smtp&cvo_cid=Integration_Sitelink&gclid=Cj0KEQiApruyBRCFqoDu1pbk9rkBEiQAF8EFdZPQBt3fGxrQgkYdLB7bxGmBDs-McRyP26_5xdYATVsaAn0_8P8HAQ): [quote]Change your SMTP username and password to your SendGrid credentials Set the server host name to [smtp.sendgrid.net](http://smtp.sendgrid.net) Use ports 25 or 587 for plain/TLS connections and port 465 for SSL connections[/quote] So I’d say that you should change port from 465 to 587 to use TLS. ---

hi Escopecz, I check this doc and change the port from 465 to 587 but still don’t work. The strange things is when I install Mautic, the Sendgrid conection was working. But now, not possible to use it. Can it be something wrong configurated on my server? Usualy Mautic should use HTTPS? Thx ---

Check the Mautic logs (app/logs dir) and server logs for a PHP error. ---

I am using a shared host (1and1) so found that in order to connect to Sendgrid, I have to select “Other SMTP Server” in Mautic then configured as follow: SMTP host: [smtp.sendgrid.net](http://smtp.sendgrid.net) TSL encryption SMTP port: 2525 username and password as usual. Hope this helps. Kind regards, Linh ---
