Email Settings for iPhone and Android

These are the settings to add your business email to a phone or desktop client. They are the same for every NexzaHost account — only the domain changes.

The settings

| Setting | Value | |---|---| | Username | your full email address | | Password | your mailbox password | | Incoming server | mail.yourdomain.com | | Incoming port | 993 (IMAP with SSL) | | Outgoing server | mail.yourdomain.com | | Outgoing port | 465 (SMTP with SSL) | | Authentication | required, same username and password |

Replace yourdomain.com with your actual domain throughout.

Use IMAP, not POP

IMAP keeps mail on the server and mirrors it to every device. Read something on your phone and it shows as read on your laptop.

POP downloads and typically deletes from the server, so mail exists on whichever device fetched it first and nowhere else. If you have ever wondered why an email is on your laptop but missing from your phone, POP is why.

Choose IMAP unless you have a specific reason not to.

iPhone and iPad

1. Settings → Apps → Mail → Mail Accounts → Add Account 2. Choose Other, then Add Mail Account 3. Enter your name, full email address, password and a description 4. Tap Next. iOS will try to detect the settings and usually fail — that is expected 5. Select the IMAP tab 6. Incoming Mail Server — Host Name mail.yourdomain.com, username = full email address, plus password 7. Outgoing Mail Server — same host name, same username and password. iOS labels the password "Optional" here. It is not optional. Fill it in or sending will fail 8. Tap Next, wait for verification, then Save

Android

Steps vary slightly by manufacturer, but the shape is the same:

1. Open Gmail (or Samsung Email) → Add accountOther 2. Enter the full email address, tap Manual setup 3. Choose Personal (IMAP) 4. Enter the password 5. Incoming — server mail.yourdomain.com, port 993, security SSL/TLS 6. Outgoing — server mail.yourdomain.com, port 465, security SSL/TLS, Require sign-in ticked 7. Finish

Desktop clients

Outlook, Thunderbird and Apple Mail use the same values. In every case choose manual or advanced setup — automatic detection guesses wrong for custom domains more often than not.

If it will not connect

"Cannot verify server identity" or a certificate warning. Your SSL certificate does not yet cover mail.yourdomain.com. Run AutoSSL in cPanel under Security → SSL/TLS Status with the mail subdomain selected. As a temporary workaround you can use your server hostname from the welcome email instead of mail.yourdomain.com.

Receiving works, sending fails. Almost always the outgoing password. iOS in particular marks it optional and people leave it blank. Fill it in and tick "require authentication".

Port 465 blocked. Some mobile networks and office firewalls block it. Try port 587 with STARTTLS instead.

"Username or password incorrect" but they are right. Use the full email address as the username. info will not work; info@yourdomain.com will.

Nothing connects at all. Confirm mail.yourdomain.com resolves — if DNS has not propagated since you set up hosting, no client will connect. Webmail at yourdomain.com/webmail is a good test: if that works and your phone does not, the problem is in the client settings.

Non-SSL ports

Ports 143 (IMAP) and 587 (SMTP) exist without SSL. Use them only if SSL genuinely will not work on a restricted network, and understand that your password crosses the network unencrypted. Always prefer 993 and 465.
