i think you still can use the email client.
blocking outbound 25..
that doesnt mean you cant connect to your mail server out there..
you're connecting to port 25 not from 25..
traffic to port 25 still widely open for me here..

their main purpose is to avoid any user to use their own email server for sending out spam..

I can't connect to email server located in US through SMTP.

I am trying to send email through my server in US by connected to it via SMTP (port 25).

I think this does get blocked as it is "outbound" mail through SMTP. Cause I have no problems using Maxis broadband doing same thing.

have u tried it with other server?..
gmail maybe.. really weird.. i can connect to my company server, gmail, and my own hosting in us too..
if they really block outbound to 25 a lot of businessman will make noise already...

What is your IP? As stated in tmnet's statement, this will be done in stages. Probably your IP range is still no implemented yet.

They are trying to block spammer. Usually, spammers sent out emails by just sending an email directly out through port 25. Don't really need to have email server.

I am going to call tmnet to complain tonight. I just hope the support doesn't piss me off to dead with their stupid questions.

yup but normally all mail server does require authentication for SMTP..
even so if you're admin you will actually doing this if your mail server is publicly accessible..
so one cant simply doing that..

diff case if you got your own email server..

go ahead make noise.. because if they really doing this...
dunno what to say.. it doesnt make sense..

Hi Asellus,

I think you do not know how SMTP operation works. Do you know that NOT only email server uses port 25 to send out emails? Email clients also uses port25 to send out emails back to their email servers.
email server to email server -port25,  email client/user to email server can also use port 25.
Maybe there was a misunderstanding on the problem or you are not aware how email clients (outlook, thunderbird) works to sent emails back to their SMTP server.

I do not have an SMTP server at home. I'm only a user using Outlook Express to send emails back to my office email server in US. Previously my outlook clients uses port 25 for outgoing emails. Now i've changed it to use a different outgoing port. I'm forturnate my corporate email server supports an alternative port. For those that don't, they will have a tough time sending email out from a email client.

Please read and understand SMTP, SMTP auth

you're so wrong dude.. asellus was right..
yup you'll use port 25 for smtp.. we all know..
but from client you'll not be using port 25 for connecting to your mail server....
tmnet block all outbound smtp traffic
means all traffic from port 25..

i know you're really think when using email client u're using port 25..
play around with netstat while sending out mail then u know..
you're connecting to 25.. not from 25..

its same thing while u browsing..
did u really think u're using port 80 at your machine while browsing this forum(webserver)?..
