Apple Mail doesn't have a "Flashcloud" preset, so it treats your address as a generic IMAP account. Add it as an "Other Mail Account," enter the server details below, and mail starts flowing in a couple of minutes. The steps are nearly identical on Mac and iPhone, since both use the same Internet Accounts system under the hood.
Before you start, create the mailbox in the portal if you haven't: Services, your hosting service, then the Email tile. Have the full address and its password ready.
Add the account on Mac
- Open System Settings, then Internet Accounts (on older macOS versions this is Mail, Contacts, Calendars).
- Click Add Account, then choose Other Mail Account.
- Enter your name, full email address, and password. Mail tries auto-discovery first.
- If auto-discovery fails (it often will, since Flashcloud isn't a big-name provider it recognizes), you'll get a manual setup screen. Enter:
- Incoming server:
mail.yourdomain.com, port993, SSL/TLS on - Outgoing server:
mail.yourdomain.com, port465, SSL/TLS on (or587with STARTTLS if 465 is blocked on your network) - Username: your full email address on both incoming and outgoing
Replace yourdomain.com with your actual domain. Full field-by-field values, including the fallback hostname to use if your domain isn't pointed at Flashcloud yet, live in Email server settings (IMAP and SMTP).
Click Sign In. Mail verifies the connection and adds the account; your inbox starts syncing within a minute.
Add the account on iPhone
- Open Settings, then Mail, then Accounts, then Add Account.
- Tap Other at the bottom of the provider list, then Add Mail Account.
- Enter your name, email, password, and a description (e.g. "Work"), then tap Next.
- iOS will try to auto-detect and usually fail the same way macOS does. When it drops you into the manual IMAP/POP screen, tap IMAP at the top and fill in:
- Incoming mail server: host
mail.yourdomain.com, username your full email, password your mailbox password - Outgoing mail server: host
mail.yourdomain.com, username and password the same as incoming
iOS doesn't show explicit port fields on this first screen. It fills in defaults and lets you verify. If verification fails, tap the account, tap SMTP under Outgoing Mail Server, tap the primary server, and confirm Server Port is 465 with Use SSL on (or 587 if your carrier or network blocks 465). Do the same check under incoming settings for port 993.
Why IMAP, not POP
Apple Mail defaults new manual accounts to IMAP, and that's what you want. IMAP keeps mail on the server and mirrors read/unread state and folders across every device, so your Mac and iPhone always show the same inbox. POP3 downloads messages to one device and can remove them from the server, which desyncs your devices fast. Stick with IMAP unless you have a specific reason not to.
Common failure points
- Username must be the full email address. Entering only the part before the
@is the single most common reason Apple Mail rejects the password. - Port and security mismatch. IMAP is always
993with SSL/TLS. SMTP is465with SSL/TLS, or587with STARTTLS. Mixing a port with the wrong security type fails silently or times out. - Domain not pointed yet. If you haven't switched nameservers to Flashcloud,
mail.yourdomain.comwon't resolve correctly. Use the alternative hostname shown on your service detail page under Services instead, then switch back tomail.yourdomain.comonce DNS propagates. - "Cannot Get Mail" banner on iPhone. Usually a password typo or airplane mode/VPN interfering with port 993/465. Delete and re-add the account if toggling settings doesn't clear it.

When to contact support
If you've matched the server, port, and security settings exactly and Apple Mail still won't authenticate, open a ticket from the portal under Support, then New ticket, or use live chat. A real person can confirm the mailbox exists, check for a typo in the password on the server side, and verify DNS is actually pointed where Apple Mail expects it.
