Help Please - I've blocked someone out

Not sure I’m in the right area, but hope someone can help.

I have downloaded the Comoda firewall, BoClean and Avast!

How do I add or remove a blocked email or web address?

I’m getting “550 relaying mail to xxxx.com.au is not allowed”

It looks like I’ve blocked someone out that I shouldn’t have.
Thanks in advance.

Hi m8 :slight_smile:

I don’t think your problem is Comodo Firewall Pro, CBOClean or Avast! related. Searching with Google I found this :

Thanks heaps.

I think I’ve read it right… It appears my address is blocked from the other end??

That is what I am thinking too :frowning:

I’ve just checked with them and they say I’m not blocked (I work a lot with them). Also they’re email system is on Gmail - don’t know if that makes a difference.

Do you know how I can check whether they’re on my blacklist on the firewall or virus scanner? I don’t seem to be able to find a tab that highlights that info.

Most Aussie ISPs (and most email servers for that matter) have blocked SMTP relaying, as a measure to reduce spam distribution. They will now forward emails only from direct logins to the domain.

For example, you may have email accounts with BigPond, iHug and TPG. If you are on a PC that is connected to BigPond, you can receive email from all three accounts, but you can only send via the BigPond SMTP server.

Hoe this helps,

Thanks Ewen and Rednose,

I kept trying to send emails to others at the same address and was able to get through to them, so I’m still a bit confused.
I am with bigpond.
And I still haven’t worked out how to view a blacklist in Avast! or Comoda to check if I’ve accidentally blocked them out.

Is it worthwhile uninstalling and installing the programs to see if it makes a difference?

P.S. Do you get called ‘Rudolph’ Rednose?

Hey Madalen,

I’m pretty sure the root cause of the problem is in how your email software is configured. Providing it is configured to ONLY send outbound email through “mail.bigpond.com” (or whatever BigPond email server you’ve been assigned to), you shouldn’t ever receive any error messages about relaying.

For exapmple, if I configure an email app to send outbound emails via mail.bigpond.com and I connect to the internet via a TPG account, any emails I send would result in a relaying error message. If I leave the email app they way it is and connect to the internet via BigPiond, I would then be able to send outbound email successfully.

All major Aussie ISPs have done this to prevent “outsiders” sending spam from their email servers.

Assuming that you have multiple email accounts, configure your email application to receive incoming emails via the respective POP (inbound) server for each account, but all accounts must be configured to use the SMTP (outbound) server of the ISP you are connecting to the internet through.

Cheers,
Ewen :slight_smile:

Thanks again - will take a look at it when I figure out how to do it! Will search for instructions.
