Can receive email but not send it (since installing/uninstalling Zonealarm personal firewall)

Hi,

I am running MS Outlook 2000 on my home PC with Windows XP installed.  About a week ago I installed Zonealarm personal firewall.  All seemed OK until I tried to send an email and it repeatedly came up with the message:

"The message could not be sent because one of the recipients was rejected by the server.  Server response: '553 sorry, that domain isn't in my list of allowed rcpthostsn (#5.7.1)'.  (Account: 'me@myisp', SMTP Server: 'smtp.myisp.co.uk', Error Number: 0x800ccc79)."

I have since uninstalled Zonealarms, as I figured that it must have been something connected with this, but I am STILL getting the error - can anyone advise?

I did try to roll-back, but didn't create a new restore point prior to installing Zonealarms (D'oh - lesson learnt!!).

Hope someone can assist...

Steve

Steve,

Not sure if you have already checked the options of outgoing server authentication..

Lazy to type it out hence this http://www.icewarp.com/FAQ/FAQFiles/1765.htm

CLose outlook , open it again and check if this would allow you to send emails without issue

Steve,

does your isp require you to login to smtp to send mails (SMTP Authentication)? If yes, you should check your settings in Outlook2000 (Account --> More Settings) if you provide the right credentials.

Have you tried creating a new profile in Outlook?  If your Outlook is installed in 'Corporate or Workgroup' mode, then you can go to Control Panel, Mail, and create a new profile.  To tell Outlook to open to that profile, you have to go back into Outlook and go to Tools, Options, Mail Services tab, and either tell it to open to the new profile or choose to have it prompt for profile to use.

If that doesn't work, I'd uninstall and reinstall Office to see if a particular component has been affected.

If that doesn't work, I'd REinstall Zonealarm, then go into the settings and set everything to be the LEAST restrictive.  Then reboot and try outlook.  If it works, then I'd go ahead and uninstall Zonealarm again.  I think that probably when you installed Zonealarm, the default settings are probably very restrictive.  And when you uninstalled it, it left components behind that are still messing things up.  So my thinking is if you reinstall it and set it to be the least restrictive as possible and that works, then when you uninstall it, even if it leaves some things behind again, the settings will still be unrestrictive.

Hope that made sense and hope it helps.
