Email sending problem

[EXHDS]

Try telnet 17.182.34.64 25
and then to other mail servers. Maybe Your provider blocks port 25...

Thanks ruycz! Vultr by default block port 25. I sent them a request and now everything works fine. This is the detail from Vultr: https://www.vultr.com/docs/what-ports-are-blocked

Hello Lesy247,
Vultr block certain ports by default, i know i had an emnail problem myself but i asked them to unblock them and they sent me this email:

Hello,

I have removed the default SMTP block on your account. Please restart any active instances via https://my.vultr.com for the change to take effect (restarting via the server itself _will_not_ work).

For reference, our ANTI-SPAM policy is listed here:
