Solved Outlook Express Email for Windows XP Tags: Outlook Express Computers Email Windows XP Last response: February 25, 2013 11:12 PM in Windows XP Share lkeeney February 13, 2013 3:33:56 PM Recently, I am unable to send email messages to two of my clients from one of my computers on my network. I am able to send email messages to these clients from other computers on the network. Here is the error I am receiving: Quote:Your message was rejected by mta7.am0.yahoodns.net for the following reason: Message not allowed -  The following recipients did not receive this message: <firstname.lastname@example.org> Does anyone know how to fix this problem?

I just sent both of these contacts test email messages to see if fixing my clock solved the problem. Edit: This did not solve the problem as both of the email messages I just sent were blocked. | Report abuse Reply to lkeeney PhilFrisbie February 15, 2013 9:23:15 PM Did you make sure the DATE was correct? | Report abuse Reply to PhilFrisbie lkeeney February 15, 2013 10:33:01 PM No, unfortunately I did not check the DATE. The date was off by one month. I corrected this, and sent a test message to one of the contacts I was having a problem with. I did not receive and immediate error reply like I did previously, so hopefully this fixed the problem. I will post here again when and if I receive a reply to my test message. Lawrence Edit: My email was received by the contact I sent it to. Hopefully, this will fix the other contact I could not send an email message to also. Thanks for you help on this problem. It is much appreciated. | Report abuse Reply to lkeeney lkeeney February 25, 2013 11:12:07 PM Best answer selected by lkeeney. | Report abuse Reply to lkeeney Register or log in to remove Ask the community Post an answer Tom's Hardware>Forum>Windows XP>Outlook Express Email for Windows XP> Related ressources: ForumOutlook Express Email for Windows XP ForumOutlook Express Email for Windows XP ForumXP 64 and Outlook Express email ForumCheck Outlook Express Email from my windows 7 computer ForumOutlook Express Email for Windows XP ForumOutlook Express Email for Windows XP ForumHow do you keep your email address when changing outlook express ?
