› How to Fix Common Mobile Webmail Issues
Mobile webmail is reliable, but occasional quirks happen — a blank page after sign-in, image-blocking that looks like broken formatting, a login loop on Safari, slow performance on a flaky 4G connection. This tutorial covers the most frequent issues UK customers report and the quickest fixes for each.
Most common causes:
- Typo in password. Mobile keyboards auto-capitalise. If your password has uppercase, confirm Shift state. Look at the "show password" eye icon to see what you typed.
- Account locked. Five failed attempts trigger a 60-minute lockout. Wait it out or ask your admin to unlock early.
- MFA prompt missed. If MFA is enabled, the TOTP prompt might be below the fold — scroll down.
- Using primary password instead of app password. If your mailbox enforces MFA for IMAP but not for webmail, the wrong kind of password may have slipped in.
Test your credentials on desktop webmail first. If desktop works and mobile does not, the problem is mobile-side (network, browser cache). If neither works, the credentials are wrong.
Sometimes the server serves desktop webmail to a mobile device. Causes and fixes:
- Forced desktop mode. In your browser menu, turn off "Request desktop site". Safari's toggle is in the AA menu on the address bar. Chrome's is in the overflow menu.
- Old user-agent string. Some older phones send a user-agent string the server does not recognise as mobile. Append
/m to the URL to force mobile: https://mail.epost.plus/m.
- Tablet landscape. On an iPad in landscape, the server may serve desktop by design. Rotate to portrait, or manually force mobile with
/m.
Mobile webmail blocks external images by default for privacy. To see images in a specific message, tap the Display images banner at the top of the message body.
To change the default:
- Settings › Privacy › External images.
- Choose Ask for each message (default), Always load from contacts, or Always load.
If a specific image still does not load even after you click Display:
- The external host may be offline.
- The URL may be HTTP (not HTTPS) — browsers block mixed content.
- A corporate proxy may be blocking the image host.
- An ad-blocker extension may be stripping tracking-pixel-style URLs.
Mobile webmail feels slower than usual? Quick diagnostics:
- Connection speed. Test at speedtest.net or
fast.com. Under 1 Mbps makes any web app sluggish.
- Large inbox. A 50,000-message Inbox is slower to paginate than a 500-message one. Archive old messages into an Archive folder to speed things up.
- Browser cache. Clear the cache if you have not in months. Settings › Safari or Chrome › Clear browsing data.
- Too many open tabs. Phone browsers slow as tab count grows. Close unused tabs.
- Device low on storage. Below 500 MB free on iOS or Android, everything slows. Clear some space.
On Android:
- Check you accepted the notification prompt. Settings › Apps › Chrome › Notifications.
- Confirm webmail push is enabled in Settings › Notifications.
- Do Not Disturb mode suppresses notifications — check it is off.
On iPhone:
- Web push requires iOS 16.4 or later and requires webmail installed as a PWA (home-screen icon).
- After install, open webmail via the PWA icon (not Safari tab). Settings › Notifications › Enable.
- iOS Settings › Notifications › [Your webmail PWA] › Allow.
- File too large. 35 MB cap on SmartXHosting. For bigger, use a Nextcloud or similar share link.
- File type blocked. Executables (.exe, .bat) are blocked as malware-prevention.
- Permission denied. Mobile browsers need file-access permission. Settings › Apps › Safari/Chrome › Permissions › Files.
- Cloud storage not connected. To attach from iCloud Drive or Google Drive, sign in to that service on your phone first.
A rare issue where you sign in, land on a page, are redirected back to sign-in, repeat. Causes:
- Private browsing mode blocks cookies essential for session continuity. Leave private mode.
- Tracker prevention in Safari is aggressive. Try Safari › Settings › Privacy › Prevent Cross-Site Tracking → off (just for webmail domain, re-enable after).
- Date and time on the phone are wrong. TLS certificate validation depends on correct clock. Enable automatic date/time.
If the home-screen icon opens in Safari or Chrome like a regular website, the PWA install failed.
- Delete the home-screen icon.
- Open webmail in the right browser: Safari on iOS, Chrome on Android.
- Ensure you are on the HTTPS URL, not HTTP.
- Re-install via Share › Add to Home Screen (iOS) or the overflow menu (Android).
If none of the above resolves the issue:
- Compare desktop vs mobile. If webmail on your laptop works and mobile does not, the problem is mobile-specific. If both fail, the problem is account or server-side.
- Try another browser. Safari vs Chrome vs Firefox — at least one should work.
- Try a different network. Switch from Wi-Fi to 4G/5G or vice versa.
- Restart the device. Resolves transient state issues.
- Contact SmartXHosting support. Raise a ticket via your Client Area. Include: device model, OS version, browser version, the URL you tried, a screenshot of any error message, and the approximate time of the attempt.
