## GMX (free) — 65 GB mailbox, IMAP after opt-in, 135 MiB SMTP SIZE

- `storage/gmx-65-gb-mailbox-imap-after-opt-in-135-mib-smtp-size` | fails-quota | evidence reported | binding none | category cloud-drive
- identity a placeholder: card and phone unknown | verified 2026-10-21 (inherited) | stale on 2026-11-05
- url https://www.gmx.com
- free tier: GMX's own storage page: "With GMX, you can store up to 65 GB worth of emails. To put that into perspective, that's around 500,000 emails!" | unit: GB | metered on: stored-bytes | read on: 2026-10-21 | source: [1]
- per-object cap: not stated | source: [1] | note: not stated
- retention: 65 GB total is the byte ceiling. Folders can be set to auto-delete on a timer, so retention is user-visible and must be left at 'unlimited'. | source: [1] | note: not stated
- egress: Unmetered; mailbox service. | metered: no
- identity: email
- interface: rest
- limits note: per-object-cap from SMTP: `smtp.gmx.com:587` -> `250 SIZE 141557760` = 135 MiB per message (identical value on mail.com, same platform). 65 GB total is the byte ceiling. Folders can be set to auto-delete on a timer, so retention is user-visible and must be left at 'unlimited'.
- interface detail: rest
- tooling: IMAP probe-verified: `imap.gmx.net:993` -> `* OK [CAPABILITY IMAP4rev1 CHILDREN ENABLE ID IDLE LIST-EXTENDED LIST-STATUS LITERAL- MOVE NAMESPACE SASL-IR SORT SPECIAL-USE THREAD=ORDEREDSUBJECT UIDPLUS UNSELECT WITHIN AUTH=LOGIN AUTH=PLAIN]`. 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.
- notes: the same as the free tier
- extras:
  - dead_end.failure_class: quota
