I haven't been able to send e-mails when connected to T-Mobile for, oh, a year at least? My e-mail provider (Rackspace) only supports STARTTLS and SSL/TLS, and T-Mobile appears to break the authentication no matter which I choose. I can receive e-mail, but not send it on 465 or 993. As soon as I get home and switch to wifi, everything in my outbox gets sent. It's mighty annoying.
- rahimnathwani 12y ago993 is for IMAP, not SMTP. Try 587.
- dangrossman 12y agoMy mistake, just a typo. The app fills in the port itself depending on what authentication mode is chosen. It's 465/587.
- junto 12y agoI wasted a bit of time yesterday trying to get a .NET application to send email using SSL/TLS via Rackspace. It turns out that .NET System.Net.Mail doesn't support implicit SSL, only explicit SSL. You'd think that Microsoft would have solved that by now. The reasoning: This is not considered a bug, it’s a feature request. There are two types of SSL authentication for SMTP, and we only support one (by design) – Explicit SSL http://www.systemnetmail.com/faq/5.3.aspx http://www.systemnetmail.com/faq/5.3.aspx
