Re: Connection Time-out when sending Email

Hi Allan

The server you are trying to send to is either not available, doesn't have SMTP running, or is not allowing you access for some reason. To prove a point, try and do the following from the superdome:

telnet mail.server.myemail 25

Port 25 is the SMTP port. If this is working, you should get a response from the remote server.

Re: Connection Time-out when sending Email

Try this smtp conversation (type the following - note: enter your domain name when requested):

telnet mail.server.myemail 25
HELO yourdomainname
MAIL FROM: root@superdomename.yourdomainname
RCPT TO: youremailaddress@yourdomainname
DATA
Subject:Hello there

This is the body
.
quit

If the mail is delivered to you, everything is working. Maybe the mailserver was down and the queued mails are sitting awaiting re-try? My example follows with the output from the remote SMTP server:

telnet a.b.c.d 25
Trying...
Connected to .
Escape character is '^]'.
220 SMTP Proxy Server Ready
HELO xxxx.com
250 +OK SMTP server V1.182.4.2 Ready
MAIL FROM: root@xxxx.xxxx.com
250 +OK Sender OK
RCPT TO: brysonk@xxxx.com
250 +OK Recipient OK
DATA
354 Start mail input, end with "."
Subject:Hello there
This is the body
.
250 +OK message queued for delivery.
quit
221 Service closing transmission channel closing connection
Connection closed by foreign host.

Re: Connection Time-out when sending Email

Hi,

Your effort is highly appreciated. Thak you very much. I already solved my problem. I asked our network guys to re-register my server on the SMTP server. Now, my email notifications is working.

Thanks.
