Router Email restriction?

[tpuk57]

Hi

Can't get my head round this one.

New PC and laptop both connect to internet via Belkin router PC by ethernet laptop by wireless.

ISP Talk Talk

Both OS XP Home

On both machines if they try to send emails (via outlook express - i think) of more than 70 characters wont connect to internet.

Webmail no problems - could this be a router firewall restriction and if so how do you change it?

Thanks, as always for all and any help

If an email of less than 70 characters goes through, I don't see how this would be a router/firewall issue.

How did you determine 70 characters (must have been a lot of trial and error)?

What error messages are you seeing when the email is rejected?

[tpuk57]

Yes a lot of trial and error apparently.

Have spoken with belkin and they suggest doing a 'ping mail' then replacing the incoming and outgoing mail servers in the mail accounts with the IP addresses that are returned.

Not sure how this will be different but guy is so desperate will try anything

If you literally try to use the command:

ping mail

you'll receive the error:

Ping request could not find host mail. Please check the name and try again.

What they probably meant is to ping the user's email server(s), (their POP3 and SMTP server names). A few examples could be:

ping mail.bellsouth.net

ping pop.foobar.com
ping smtp.foobar.com

ping mia.mail.att.net

Have you tried using OE with email accounts other than your ISP (such as Hotmail, GMail)?

I use OE to monitor four email accounts including the above. If you can send mail using Hotmail, but not your ISP, then your ISP is where the issue resides....

Re the ping mail - thanks - used ping mail rather than the full text -

Just not sure if replacing the smtp. etc with the IP address would address the issue, and if it does why.

The ISP Talk Talk have been unable to shed any light on this matter despite hours of phone calls to their tech support.

As far as I know user only has the one account but will give anything a go.

Looks like "mail.talktalk.net" may work for both the POP and SMTP email servers.

If that doesn't work, you might try "smtp.talktalk.net" for the SMTP (Send) server and "pop.talktalk.net" (or "pop3.new.talktalk.net") for the POP3 (Receive) server.

Ok tried as belkin suggested but no joy

Anyone know if talk talk parental control or security settings restrict email sending

[jdc2000]

Things to try:

Try replaceing the mail server name(s) with the IP addresses. If that fails, try replacing the router with a different one.

[Train]

Bypass the router.
If it works, then I would say the router is blocking something.

If it does not fix it, then the problem is in your computer.

[tpuk57]

Tried replacing server names with with IP address's no difference.

Going to take my laptop over to clients and try connecting wirelessly and see if any restriction on my email.

Hopefully this will show if it is the router or something to do with the Talk Talk setup.

Ok - having visited site and eliminated Firewall, Antivirus and Router as being the cause have come to the conclusion that the MTU must be set too low. Will revisit site and post back if this rectifies prob.
