SMTP mail server

[winzip]

I have mail server userid , password of a remote SMTP mail server. ( 625 port)
I also have mail sender ID.



I want to check whether remote SMTP mail server is working or not.

How do I check that SMTP server can send email to recipients from my ubuntu box?

I have ubuntu server 10 OS ( no GUI)

port is 465 ( The site deals with port 25....)

How do I send email for port 465?

[Cheesemill]

Just replace 25 with 465 in the initial telnet command.

[winzip]

SMTP failed in command line ...

Can you please tell what could be the issue ?

Here I'm trying to connect a remote SMTP mail server running at 465 port

user@user:~$ telnet xxx.xxx.x.x 465
Trying xxx.xxx.x.x...
Connected to xxx.xxx.x.x.
Escape character is '^]'.

helo xxx.xxx.x.x
Connection closed by foreign host.


(For security reason I have masked the IP)

Can you please tell what is the issue ? I see telnet is working ...that means SMTP mail server is running

.....then why helo command fails ? Where is the problem ? How do I troubleshoot ?

As far as I know port 465 is used for secure connections, so you cannot talk in plain text.
