Hi,

Your SMTP server configured is not reachable. It is a configuration or network issue.

I strongly suggest you to use only supported tryton series.

my network is fine and about the configuration of trytond.conf i have copy just the workful statements that i already used for my tryton 6.0 and work normally.
this is my own configuration (settings smtp) on trytond.conf
```auto
[email]
uri = smtp+tls://alvarespokomi@gmail.com:xxx@gmail.com:587
from = alvarespokomi@gmail.com
```
is there other settings i should made !

The error says it’s a network issue. Please try to telnet the Gmail service from your server before any further validation.

If you’re in a linux server:
$telnet [smtp.gmail.com](http://smtp.gmail.com) 587

_I use tryton 6.0.x on a linux server. and succed today to configure it_
A) i installed postfix and configure to use a smarthost (i choose internet with smarthost)
[https://www.cyberciti.biz/faq/how-to-configure-postfix-relayhost-smarthost-to-send-email-using-an-external-smptd/](https://www.cyberciti.biz/faq/how-to-configure-postfix-relayhost-smarthost-to-send-email-using-an-external-smptd/)
postfix system name mail is the user name server that you will use to send mail. for exemple if your FAI is [fai.com](http://fai.com) and you smtp user is [user@fai.com](mailto:user@fai.com) the system name mail (in postfix configuration) is [fai.com](http://fai.com)
get the infos from your isp for smtp to tweek main.conf
you will have to install one or 2 module more (postfix tells you in /var/log/messages/mail.info) i can’t remember i am not with the computer i tweek
B) in postfix main.conf
myhostname =[fai.com](http://fai.com)
C) ou must rename the from header in postfix

at this moment the mail command can use the fai’ smtp

in tryton.conf you must configure the mail from info
```auto
[mail]
from="Sender Name"
```
i did not touch anything else and it worked
