Setting Up Emails On Your Iphone

General Mail Setup
After you’ve set up your email on the server and know your email password, you can add it to your iPhone. The steps below cover iOS 18 and iOS 26 — the wording may differ slightly on older versions, but the fields you enter are the same.
Net3000 mail server settings
  • Incoming Server: rsb13.rhostbh.com
    • IMAP Port: 993 (SSL)
    • POP3 Port: 995 (SSL)
  • Outgoing Server (SMTP): rsb13.rhostbh.com
    • SMTP Port: 465 (SSL)
  • User Name: your full email address (e.g. [email protected])
  • Password: your mailbox password
  1. Open Settings on your iPhone.
  2. Tap Apps, then Mail. (On iOS 17 and earlier, scroll down and tap Mail directly.)
  3. Tap Mail Accounts → Add Account.
  4. Scroll to the bottom of the provider list and tap Other.
  5. Tap Add Mail Account.
  6. Enter your Name, full Email address, Password, and a Description (e.g. “Work”), then tap Next.
  7. At the top of the next screen, choose IMAP (recommended) or POP. See the note below to decide which.
  8. Under Incoming Mail Server, enter:
    • Host Name: rsb13.rhostbh.com
    • User Name: your full email address
    • Password: your email password
  9. Under Outgoing Mail Server, enter the same details:
    • Host Name: rsb13.rhostbh.com
    • User Name: your full email address
    • Password: your email password
    The User Name and Password are required even though iOS labels them “Optional”.
  10. Tap Next. iOS will verify the account — this can take a minute. If you are prompted about SSL, tap Yes to keep it on.
  11. Choose what to sync (Mail is on by default), then tap Save.
Verifying or correcting the ports
iOS sets the ports automatically when SSL is on (993 for IMAP, 995 for POP, 465 for SMTP). If mail does not send or receive, confirm the ports manually:
  • Go to Settings → Apps → Mail → Mail Accounts, tap your account, then tap the account row again to open its details.
  • Incoming: scroll to Advanced. Use SSL should be on, Authentication should be Password, and Server Port should be 993 (IMAP) or 995 (POP).
  • Outgoing: tap SMTP → rsb13.rhostbh.com. Use SSL should be on, Authentication should be Password, and Server Port should be 465.
Once the account is saved, send a test email to yourself to verify both sending and receiving work.
IMAP vs POP: iOS selects IMAP by default. IMAP keeps your messages on the server so the same mailbox stays in sync across your iPhone, computer, and webmail. POP downloads messages to one device and (by default) removes them from the server, which means messages downloaded on your computer will disappear from your iPhone. Choose POP only if you specifically want messages stored on the iPhone alone.
