Please refer to the e-mail client settings detailed in this post and adjust your settings as necessary.

Re: cant send email

As far as no e-mails in SmartZone, do you have Outlook Express set up to leave a copy of messages on the server?   If not, then they are deleted from the Comcast servers when you download them into Outlook Express.

Re: cant send email

Do you have your SMTP server name as smtp.comcast.net???   I noticed in your first post that it was just comcast.net

Re: cant send email

I did change it to SMTP.comcast.net, but I believe Outlook auto types SMTP anyway.I still get the failed message.

The host 'SMTPcomcast.net' could not be found. Please verify that you have entered the server name correctly. Account: 'comcast.net', Server: 'SMTPcomcast.net', Protocol: SMTP, Port: 587, Secure(SSL): Yes, Socket Error: 11001, Error Number: 0x800CCC0D

 

 I haven't changed any sttings myself, and it only stopped sendeing mail recently. I did notice however that my settins of leave a copy on server had been changed.

You are missing a period between smtp and comcast in your smtp server name.

Re: cant send email

Added the period and now I get this message :

 

The message could not be sent because the server rejected the sender's e-mail address. The sender's e-mail address was 'patacke@comcast.net'. Subject '', Account: 'comcast.net', Server: 'SMTP.comcast.net', Protocol: SMTP, Server Response: '550 5.1.0 Authentication required', Port: 587, Secure(SSL): Yes, Server Error: 550, Error Number: 0x800CCC78

Re: cant send email

You need to check the "My outgoing server (SMTP) requires authentication” box.

Re: cant send email

You need to turn on outgoing authentication, like this:

I am quite new to this and tried for 2 days to solve this, even tried sending from my ymail account to my comcast e-mail and ,what do I see? you guessed it, address is invalid,the same notice on all e-mails.So on my way to check out my settings that dissappeared in 2 days,and no one else lives here so, the Gremlins krept in and messed me up. Thank you again. Fran     fmp1088882@comcast.net

"An unknown error has occurred.

 

Subject ''

Re: cant send email

Disregard.

 

 I wasn't thorough and it didn't help. Then I checked the security box (SSL) on outgoing email and it did it.

 

Everything works now.

Re: cant send email

What happens when you check the box to delete an email and click on the Delete icon?  Try clearing your browser cache too.
