What you experienced is normal. As a general rule, the owner of
the SMTP server must be the same as the one providing your Internet
connection at that moment. For more on this see
http://www.postcastserver.com/help/Port_25_Blocking.aspx
The available workarounds when sending away from home are as follows:
1. Use webmail for sending (via your browser).
2. Ask your home ISP if they have a port other than '25' for SMTP.
3. If you use the same away-from-home connection frequently, substitute the SMTP
server belonging to that connection. This is a bit tricky, but if you want to go that route,
I can provide more details.
4. If you frequently send from multiple locations, get a free Gmail account,
configure it for POP access, and use it for your sending chores.
Gmail uses port 465 for SMTP, which is not blocked like port 25 is.

Telnet shows me that port 25 cannot be accessed..
Windows Mail gives the following error message
The connection to the server has failed. Subject, Account: , Server:,
Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10060, Error Number:

Dear all,
For the last 2 weeks I'm experiencing a major problem with Outlook 2007
(Vista 32 bit) AND Windows Mail. I cannot send emails.
Something is blocking port 25 and it aint the ISP, for sure. (so no
smtp.isp.com is required). Yes, I checked telnet.
I am perfectly able to receive emails in both Outlook and Windows Mail.
How do you know the port is blocked? What error message do you receive when
you try to send a message to yourself?
