hi,
I got this for the first time today, which is why I joined this community.
I'm using W XP, IE 8, my ISP is Demon, my email software is Pegasus 4.62 (latest version)
I switched off the output email scan and the emails go without any problem. Switch it back on and they don't go with this error number.
So it's not my ISP. I think it must be something about Norton Internet Security. I've upgraded to 2012 but no change.
Norton now wants me to fix something. Yes, you've guessed; it's the outgoing email scan. I read from someone that there's an ignore button. Not on my version; well nowhere that I can find anyway.
Trouble is, I can go on 'manually' ignoring the warning, but what about if there really is something that needs my attention?
