Check to make sure you are not dropping packets to port 113 (ident).
If you are doing this and your ISP is running an MTA such as sendmail then you will get a TCP timeout before you are able to send mail and this can be a good two to three mins in some instances (it seems like 10 when you are sitting and waiting)
Remember, security by obscurity is no real security - simply dropping all inbound packets wont tell someone you are not there (you did after all initiate a communication with the mail server). Rejecting traffic by sending back an ICMP port unreachable is usually a far better way to go unless you have a specific reason to silently drop packets.

Hi, so sorry for the late response. Well, because this thing happens to Mozilla mail, so i tried to set up Ximian Evolution mail with the same configuration. Turned out that the email could be delivered, but takes 10 mins more or less. Im trying to contact my ISP and ask them about the SMTP server.
Thank you for all replies. TuanAnh

Check the SMTP server setting in your mail software. Such a situation most probably means that your computer is trying to connect to nonexistent SMTP server. It is also possible that there is some problem
with SMTP server itself and it does not accept connections at that time.
You also can use for mail transmission your own SMTP server running on your computer (if your ISP allows it).

Im sorry for this uninformative question. But im quite a newbie in Linux
world. I bet the configuration i set up were the same as that which worked
before. There's no error at all. When i sent an email from my hotmail
account to that account, it recieved well.
But whenever i tried to send an email to wherever, it just hang up with
the message "Sending email .... ". I have to click Cancel and it said the
message's not been sent.
