Built-in providers
FOLD ships server profiles for eleven mail providers; every other address is set up through DNS, your domain's autoconfig file or by hand.
The eleven profiles
A built-in profile matches the domain after the @ exactly, including the listed alternative domains. All incoming servers use port 993 with implicit TLS. For outgoing mail, port 465 uses implicit TLS and port 587 uses STARTTLS.
| Provider | Addresses | Incoming (IMAP) | Outgoing (SMTP) | Sign-in |
|---|---|---|---|---|
| Google Mail | gmail.com, googlemail.com | imap.gmail.com | smtp.gmail.com:465 | Google sign-in |
| Microsoft Outlook | outlook.com, hotmail.com, live.com, msn.com, outlook.de, hotmail.de, live.de | outlook.office365.com | smtp.office365.com:587 | Microsoft sign-in, not available yet |
| iCloud Mail | icloud.com, me.com, mac.com | imap.mail.me.com | smtp.mail.me.com:587 | App-specific password |
| Yahoo Mail | yahoo.com, ymail.com, rocketmail.com, yahoo.de, yahoo.co.uk | imap.mail.yahoo.com | smtp.mail.yahoo.com:465 | App password |
| Fastmail | fastmail.com, fastmail.fm, fastmail.us | imap.fastmail.com | smtp.fastmail.com:465 | App password |
| GMX | gmx.net, gmx.de, gmx.com, gmx.at, gmx.ch | imap.gmx.net | mail.gmx.net:587 | Password |
| WEB.DE | web.de | imap.web.de | smtp.web.de:587 | Password |
| Posteo | posteo.de | posteo.de | posteo.de:465 | Password |
| mailbox.org | mailbox.org | imap.mailbox.org | smtp.mailbox.org:465 | Password |
| Telekom / T-Online | t-online.de, magenta.de | secureimap.t-online.de | securesmtp.t-online.de:465 | Password |
| Zoho Mail | zoho.com, zohomail.com, zoho.eu | imap.zoho.com | smtp.zoho.com:465 | App password |
Notes on individual providers:
- iCloud Mail requires an app-specific password when two-factor authentication is on. You create it at appleid.apple.com.
- Yahoo Mail, Fastmail and Zoho Mail accept third-party mail apps only with an app password from their account settings.
- GMX and WEB.DE have IMAP access switched off by default. Turn on “POP3/IMAP Abruf” in the provider’s settings before you add the account.
- Microsoft addresses are recognized, but sign-in is not possible yet; see Sign in with Google.
The profiles are part of the app and change only with an app update. An updatable, signed provider database is planned.
All other providers
For any other domain, FOLD asks the DNS SRV records of the domain and the domain’s own autoconfig file, as described in Add your first account. If one of them points to a server outside your domain, you confirm the host with Trust this server before FOLD connects.
If nothing is found, FOLD opens the manual setup with imap.<domain> and smtp.<domain> prefilled. Your provider’s help pages list the correct values.
After a successful lookup, FOLD remembers the result for that domain on this device for 30 days, so a second address at the same domain is set up without a new lookup.
