A desktop mail client for PEC, REM, and IMAP.
Unwraps PEC/REM envelopes, shows the operator’s delivery evidence, and keeps original .eml files plus a searchable SQLite archive. It connects to mailboxes you already have — Gmail, Microsoft 365, Italian PEC gestori, and generic IMAP/SMTP. Mail never leaves this PC for search.
Reads the inner postacert.eml and shows accettazione, avvenuta consegna, and ETSI evidence (SubmissionAcceptance, Delivery, Retrieval). PEC avvenuta consegna is deposit in the certified mailbox. The app shows gestore / QTSP evidence; it does not issue a qualified receipt.
IMAP, POP3, and SMTP to Gmail, Microsoft 365, Aruba, InfoCert Legalmail, Namirial, Poste, Register.it, Libero, Intesi, and custom hosts. Gestore password or Identity Hub (XOAUTH2) for Google and Microsoft. Folder stores hold .eml on disk with no password and no SMTP.
The whole IMAP folder in mail.db plus .eml on disk. Keyword search, optional on-device EmbeddingGemma, practice labels, and spam marks stay on this PC. Optional boot-time sync refreshes saved mailboxes with nobody signed in.
Readable FatturaPA XML preview. Export of original .eml files. Import EML, mbox, and Outlook PST into a folder store. Easy Migration packs mail, accounts, and secrets into a passphrase-locked .postbundle.
English, Italian, French, German, Spanish. Country packs under Settings → Features (Italy, Europe, France, Germany, Spain, Switzerland). Ordinary IMAP stays available when packs are off.
Windows (portable zip and setup, no .NET SDK required), Linux Flatpak, macOS DMG (Apple Silicon and Intel). macOS builds are unsigned; first launch is Open from the context menu.
Envelopes and receipts come from the gestore / QTSP; Postclient opens them and keeps them locally. It is not a qualified trust service provider, not a PEC operator, and not hosted mail.
Gmail / Microsoft sign-in: Identity Hub privacy and terms.
