Could some educate me as to what this means:
“An error occurred while sending mail. The mail server responded: Service Unavailable; Client Host [Removed] was blocked using dun.dnsrbl.net. Please verify that your email address is correct in your Mail preferences and try again.”
Apparently my mail was blocked, outgoing. I think. I’m confused.
Yeah, it means that whereever you’re sending from is listed in, apparently, a dial-up IP list that your mail server is using to deny you access. If it’s Hindenburg, yell at Jason, it shouldn’t be doing that if you’re authenticating.
Hmm, I’m trying to send mail from work, using Hindenburg as my outgoing. So, is that a problem with my IP at work being list and hindenburg blocking it? Or is it that hindenburg is blocking it on the outgoing side?
why did I sign the bottom of that post. I’m a numbnut.
Do you use the SMTP authentication? Username and password (same as your UNIX login) should operate fine for you. It bypasses any restrictions I have in place.
By authentication do you simply logging in with the user name and password or do I need to use TSL or SSL? I haven’t been using either and it’s been working fine from home for months and months. This just started two days ago here at work. I haven’t changed anything.
I won’t give out the server address, but I’m using port 25 and logining in as usual.
Like I said, this is only happening at work. At home it works fine, and as far as I know the settings are identical.
Not that it’ll help, but I’m using Thunderbird 0.7 in both cases.
