Forté Agent 8 under Wine

Tested setup details for preserving an established Agent installation and a large mail/news archive on Linux.

Status: documentation, not an installer. This guide describes the combination tested on one Debian host. The Wine and profile details are provided below; the custom POP bridges are not yet packaged for public installation. This documentation package alone does not reproduce the complete mail service.

Last evidence update: September 19, 2026.

Installation instructions: see Agent 8 on Debian 12 for the dependency list, build/install recipes and first-run procedure. These instructions are reconstructed from this working host, not clean-machine verified. A fresh Agent installation, startup, default-folder navigation and normal exit were tested here. The custom POP bridges remain excluded.

1. What works

Larry tested the application on the desktop while OpenAI Codex performed the investigation, build and integration work. The Wine patch described here is upstream Wine work, not a fix invented by Codex.

Other SMTP providers, attachments/BCC combinations, encrypted NNTP and binary-news features have not been established by these tests. Text rendering still has some rough edges. Hotmail OAuth support has not been integrated.

2. Tested environment

Linux Mint has not been tested here. Neither has a clean-machine installation of this guide. These are the known working components, not a claim that this exact old Wine version is required or that newer versions lack the fix.

3. Wine build and input fix

The Wine 11.14 source used here includes upstream commit a1bae27f21b53fa3ac6be6b08f4cbfb441360ade, titled “win32u: Don't ignore raw mouse input.” It changes dlls/win32u/input.c and references Wine bug 59986.

• Upstream commit and complete diff
• Wine bug 59986

Failing sessions on this host produced very large numbers of unknown-input diagnostics. Successful interactive sessions followed the corrected build. That evidence does not prove every earlier retrieval crash had the same cause.

For an exact-version build, obtain the official Wine 11.14 source and apply the referenced upstream change. Configure in a separate empty build directory and install into a separate Wine installation directory. Do not overwrite the distribution Wine. If using newer source, first determine whether it already contains the fix; do not apply it twice.

These are configuration references, not commands to paste:

The LLVM tools, including llvm-dlltool, mattered. An earlier GCC/MinGW build failed in oleaut32's VarR4FromUI8; the Clang build path avoided that failure. Normal Wine build prerequisites, including development libraries, Bison and Flex, are still required. This guide does not provide a verified complete dependency list for another machine or distribution.

Both patched and unpatched builds can report wine-11.14. That version string alone cannot prove the fix is installed. Use the intended Wine executable and its matching wineserver, rather than accidentally mixing installations.

4. Preserve the profile before testing

The executable and message database are different parts of the installation. In the tested prefix they reside under Program Files (x86)/Agent and the Windows user's AppData/Roaming/Forte/Agent, respectively. Determine the data directory actually used by your own installation before copying anything.

The following is a migration checklist, not a command sequence or authorization to overwrite an existing installation:

1. On the source Windows installation, as its owner: close Agent normally before making a backup/copy. Keep the original untouched. Stop if Agent cannot close cleanly or the backup cannot be verified.
2. On the destination Linux desktop, as the ordinary user: create a separate Wine prefix using the intended runtime, and install your licensed Agent. Expect an independent installation. Stop if it points at your only archive or would overwrite an existing prefix. Do not try to change an existing prefix's architecture by changing an environment variable.
3. With Agent closed on both systems: place an independent writable copy of the complete profile in the destination's correct data directory. Preserve settings, indexes, filters and mail UID tracking together, not just selected .DAT files. Verify the copy and the desktop user's access to its parent directories. Stop on a mismatch or unexpected existing destination. Do not hard-link a writable store to the only backup.
4. On the Linux desktop: first open that copy with provider access blocked independently of Agent's saved settings. Expect the original folders and readable old messages. Stop if the wrong profile appears, a new-account wizard unexpectedly opens, or the program hangs. Do not enable networking to work around an offline/profile failure.
5. In the responsive Agent window: close normally after checking the archive. Expect the application to exit. Stop further tests if it hangs; preserve the backup and investigate before reopening the working copy.

Do not let Windows and Wine write the same store concurrently. A Wine prefix is a separate environment, not by itself a network or security sandbox.

The setup carried forward Wine Gecko 2.47.4 x86. No Microsoft .NET requirement was demonstrated for the tested Agent functions. For reference, the launcher uses WINEDLLOVERRIDES=mscoree=d;winemenubuilder.exe=d, disabling CLR loading and Wine's automatic menu generation. This is an observed setting, not a claim that every Agent installation needs these overrides.

5. Usenet and outgoing mail

Giganews header/body retrieval, composition and posting worked. The progress article in alt.usenet.offline-reader.forte-agent was posted from Agent under Wine and retrieved afterward; it was not a local simulation.

The tested news connection used port 119 without encryption, by Larry's choice. Unencrypted NNTP can expose authentication and article traffic. This is not a recommendation to disable encryption elsewhere, nor a test of encrypted NNTP.

Because Agent is network-isolated in this deployment, a standard socat byte relay supplies the selected news connection. It is a transport path, not a replacement NNTP client or OAuth adapter. Its use here does not demonstrate that an ordinary Wine installation requires a news proxy.

For an initial online test in your own installation, inspect old Outbox items first and begin with headers and one article body from an existing subscription. Expect a successful task, possibly with zero new headers. Stop on errors. Do not use Send All as a connectivity test. Before any intentional post, verify the group, identity, content and absence of unintended email recipients.

The AT&T SMTP test used Agent's existing TLS/login settings through a byte relay to the selected SMTP service. A successfully delivered plain-text message qualifies that path, not all email functions or providers.

News posting and emailing a copy are separate operations. The original Usenet post succeeded while its added email BCC failed. On a partial or ambiguous result, check whether the article already appeared before retrying; otherwise a second news post may be created.

6. The custom POP component

This is the largest difference between the tested deployment and simply installing Agent under Wine. Agent talks to local POP listeners; native Linux helpers connect to real mail providers over certificate-verified TLS.

Each poll inventories the server's UIDL/LIST snapshot, compares retained delivery tracking and offers untracked messages to Agent. Bodies are fetched on demand using disk-backed temporary storage. Agent continues applying its local routing filters. Completed deliveries are recorded across sessions.

Current limits are:

• Up to 1,000 messages and 256 MiB per account per poll.
• Up to ten polls per session.
• A 10 MiB maximum per message.
• Inventory bounds of 100,000 rows and 8 MiB per metadata response.

The old ten-message-per-account limit no longer describes this launcher. Nevertheless, “all new mail” is still subject to these safeguards. Another successful poll can continue resource-limited work. Oversized messages remain on the provider. An error requires investigation, not an automatic retry. Zero remaining describes the checked snapshot, not an empty server mailbox or the absence of later arrivals.

Server retention is deliberate: the upstream helper does not implement POP DELE, and the local side rejects deletion requests. Account-level “leave on server” settings alone were insufficient because some existing filters had their own deletion overrides. Those overrides were cleared without removing the routing rules and have not been restored.

A generic TLS tunnel does not supply this inventory, duplicate tracking or no-delete enforcement. The custom bridge is not included in this documentation package and is not yet a portable public package. Its configuration and supervision are host-specific. Publishing an installer or configuration-independent bridge would be additional work; there is no download promise or release date here.

7. Troubleshooting lessons and remaining limits

Normal use now has persistent disk-backed profile storage, not the limited RAM overlay used in that test. These explanations apply to the observed incidents, not every superficially similar symptom on another machine.

The archive's size alone did not explain the earlier problems: the established archive remains in use. We have not verified every historical message, every provider, attachment type or binary-news feature.

8. Useful information from other users

When describing a problem, include the Agent build, Wine version and patch status, distribution, desktop/session type, whether the profile is new or migrated, the failing operation and a short sanitized error excerpt.

Do not upload complete profiles, account configuration files, mailbox inventories, credential/token files or unreviewed logs. An installer failure, an offline folder-navigation hang and a provider authentication rejection need different investigations.

This package contains documentation only: no proprietary Agent installer, Wine binaries, mail archive, account credentials or private diagnostic logs. It is an experience report, not an official Forté, Wine or OpenAI support product.
