Unable to configure my SMTP email

[J4N]

Hi,

I've installed JIRA on my windows computer(Running as service), and when I configure the SMTP domain, I got this message:

Unfortunately no connection was possible. Review the errors below and rectify:
SocketTimeoutException: Read timed out

But, if I do a telnet USED_MAIL_HOSTNAME 25 I get answer directly, so what could make that the tomcat/java is unable to connect?

Previously, I was having a SocketException, due to JIRA using IPV6 to connect to the server. This is no longer the case after the manipulation indicated here:https://confluence.atlassian.com/jirakb/error-socketexception-network-is-unreachable-connect-when-setting-outgoing-smtp-mail-server-in-jira-780865909.html

What about the setenv.bat? Did you set a proxy?

No, I didn't change anything, I thought that if my computer was able to do a telnet, java running on the same computer should also be able to do it?

Can you try setting a proxy (if you use a proxy)?

JIRA is starting in an own environment (JVM) so it has own settings. Hope that helps.

I've no proxy set in internet explorer or chrome, so if there is one in the company, I have to admit that I don't know it
