email won't allow me to send an attached zip file

[Deano]

My Windows mail will send an email message w/o attachments with no problem,
but not with attachments. I tried to increase the timeout to 5mins maxium and
I still receive this error...

Your server has unexpectedly terminated the connection. Possible causes for
this include server problems, network problems, or a long period of
inactivity. Subject 'tnb doors inc -shop pics', Account: 'mail.comcast.net',
Server: 'SMTP.comcast.net', Protocol: SMTP, Port: 25, Secure(SSL): No, Error
Number: 0x800CCC0F

any help would be highly appreciated, thankyou in advanced.

Comcast made some changes in their email settings. Follow these steps:

Note that the outgoing server now requires port 587 rather than port 25.
Also, "My server requires authentication" must be checked.
