IMAP is OFF by default and must be toggled on in settings (documented, not a paywall). Same server identity as mail.com — the IMAP banner H migmxus005 is byte-identical in shape to imap.mail.com's. |

| Composes with | 65 GB × N free accounts. GMX and mail.com are both United Internet properties, but only GMX leaves IMAP open on the free tier — so GMX is the reachable half of that 130 GB pair. |

| Reliability | Free accounts are deleted for inactivity; IMAP access is auto-revoked "for security reasons" after a long period of non-use, so a dormant archive mailbox can lose its programmatic path. |
