Hi, I'm hoping someone can help me with this. When I recently moved to a new apartment, and finally got internet again through Cablemas, I can receive e-mail on my domain name email accounts using Outlook, but can't send any e-mails. I get this error: Sending' reported error (0x80042109) : 'Outlook is unable to connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).' I've always had Cablemas internet here and never had this problem until I moved to a new apartment. Shortly after this problem showed up, I went back to the U.S. for awhile, and I could receive/send emails just fine. Now that I've returned to Cancun, I've got the same problem: I can receive emails, but can't send them. So I'm thinking the problem is with Cablemas, correct? Are they requiring me to use their outgoing SMTP server rather than the one provided with my domain? Has anyone else had this problem and/or know what the outgoing SMTP server is for Cablemas? I've done a web search on this error, and can't make sense of the suggested solutions considering I can send e-mails just fine from another ISP.
