Our verdict on intrvll Hosted Mailboxes

intrvll Hosted Mailboxes provides custom-domain email hosting for small teams that want mailbox sizing to match individual needs. The service includes webmail alongside IMAP retrieval, SMTP submission, CalDAV calendars and CardDAV contacts, so teams can connect standard email and productivity clients. Mailboxes are hosted on the vendor’s European infrastructure with EU-only data residency, while aliases and catch-all addresses support shared or role-based address patterns.

Pricing is straightforward and billed monthly per inbox. The Mailbox · 5 GB plan costs €2 per inbox per month, the Mailbox · 15 GB plan costs €5, and the Mailbox · 50 GB plan costs €15.5. Each mailbox tier includes IMAP, SMTP, CalDAV, CardDAV and webmail. The service also offers monthly prorated billing without a minimum term, letting teams choose storage per inbox rather than adopting one fixed size for everyone. Aliases and catch-all addresses are included, with aliases available without a stated limit.

The strongest operational features are flexibility and email administration. Mailbox resizing can happen without downtime, daily backups are retained for 30 days, and IMAP migration assistance can support a move from another provider. SPF, DKIM and DMARC generation, spam filtering and virus scanning add domain-authentication and message-filtering capabilities. Teams that want standard protocols, European hosting and adjustable mailbox capacity should find the offering well aligned. Organizations seeking a vendor-native mobile experience or broader platform coverage should consider whether third-party apps and webmail fit their workflow.
