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
http://en.wikipedia.org/wiki/Simple_Mail_T...ail_SMTP_serverhttp://en.wikipedia.org/wiki/SMTP-AUTHyou'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)?..
