Outlook Express

I am not sure if this is the right place for this, but I ran my anti-virus and did not find anything.
I run Windows XP with Outlook Express.
Have not had any problems till today. Computer is new since Christmas.
Now, I cannot send any messages. ZA comes up with alert telling me it is blocking my outgoing mail. I tried turning ZA off just to see what happened, but still get this error message. Anyone know how to help ?

The message could not be sent because the server rejected the sender's e-mail address. The sender's e-mail address was 'lonne@sytekcom.com'. Subject 'Fw: FIRE HAZARD', Account: 'mail.sytekcom.com', Server: 'mail.sytekcom.com', Protocol: SMTP, Server Response: '550 This system is configured to reject mail from XXX.XXX.XX(DNS reverse lookup failed)', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC78a

 

You might try uninstalling ZoneAlarm, running a registry cleaner to remove all traces of the application, and then try your email again. I'm not a big fan of ZoneAlarm as it has caused problems on a few PC's for me, and I've switched to Sygate, which doesn't have the cartoonish interface and seems to work great. Reread your post, and it could be that the person that you are trying to send email to has blocked you, although it could have been unintentional!

 

I thought of the fact someone may have blocked me, but I tried sending to myself and to my mom, who I know doesn't have me blocked. Still didn't work.


Thanks for the help. Think I will will uninstall Za and download it again. I have never had trouble with it before.

May I suggest reading the FAQ's onsite, particularly those pertaining to spyware?


It is surprising how often that seemingly terminal computer poblems are solved by maintenance.

No snark intended, FYI

 

I am not sure what you mean. I have ran adaware, spybot, spysweeper,cwshredder, plus I run an online scan at least once a week.

I looked thru the FAQ,and did a search to see if others have had this trouble and did not find anything.

Well, I uninstalled ZA and am trying Sygate, bur this us not what is the problem with my Outlook Express. The outgoing mail is still blocked. Hopefully, it is a problem with my server, and not something with the computer. I will check it again in the morning.
