GoAutoResponder | Automated Email Reply System

Multi-Account IMAP/SMTP Email Auto-Reply Software

GoAutoResponder is a Windows application for monitoring incoming email across multiple IMAP accounts and automatically sending configurable replies through the corresponding SMTP servers.

It is designed for authorized business and internal email workflows where incoming messages need to be filtered, processed, and answered automatically. The package includes ready-to-use Windows executables, multilingual graphical interfaces, detailed documentation, message template examples, and the complete Go source code.

Key Features

• Multiple email accounts: process multiple IMAP and SMTP accounts from one account list.
• Multi-threaded processing: configure the number of concurrent workers and the delay between them.
• Three operating modes: auto-responder, account validation with list cleanup, and validation-only mode.
• Flexible processing cycles: run continuously or for a specified number of cycles.
• Unread or all messages: reply only to unread emails or process all matching emails.
• Subject and body filters: process emails only when configured phrases are found.
• Ignore filters: skip delivery failures, automated replies, notifications, and other unwanted messages.
• Recipient blacklist: supports exact addresses and wildcard masks.
• Per-recipient reply limits: prevent repeated replies beyond the configured limit.
• Per-account cycle limits: limit how many messages one SMTP account can send during a processing cycle.
• Configurable delays: apply a randomized delay between replies.
• Optional message deletion: independently control deletion of replied, ignored, or over-limit messages.
• Contact collection: save information extracted from incoming messages.
• Detailed output lists: separate valid, invalid, malformed, SBL-listed, and successfully used accounts.
• Debug logging: save diagnostic information and optional copies of sent or processed messages.

Powerful Email Templates

GoAutoResponder uses editable MIME templates consisting of a header file and a body file. You can create plain-text, HTML, multipart, Base64, quoted-printable, and Outlook-style message templates.

The built-in macro system supports:

• Sender and recipient email addresses and display names.
• Original Subject, Message-ID, References, and In-Reply-To headers.
• Original incoming-message content and cleaned message text.
• Random subjects, links, domains, first names, and last names.
• Masked and Base64-encoded address variants.
• Random selection from multiple values.
• Random numbers and generated character sequences.
• Static random values shared between the header and body of one message.
• Custom date and time formats with minute-based time shifting.
• External text files with configurable fallback values.
• MIME header encoding and body encoding.
• Original reply text and quoted-message content.
• Template string replacement and repeat operations.

A complete reference for every supported macro is included in the English and Russian documentation.

Attachment Support

• Attach one randomly selected file or multiple configured files.
• Standard attachment and inline attachment methods.
• Random or explicitly selected files from the attachment directory.
• Custom attachment display names with macro support.
• Macro processing inside supported text-based attachments.
• MIME attachment insertion for advanced custom templates.

Optional OpenAI Integration

GoAutoResponder can generate reply text using the OpenAI API or a compatible API endpoint. The cleaned text of an incoming email can be inserted into a configurable prompt using the OPENAICHATGPT[] macro.

• Configurable API base URL.
• Configurable model ID.
• System and user instructions.
• Maximum output token configuration.
• Temperature support for compatible models.
• Configurable fallback response for failed or unavailable API requests.
• HTML escaping of generated text before insertion into the email template.

Important: an OpenAI or compatible API account is not included. API availability, billing, usage limits, and generated content are controlled by the selected API provider.

Proxy and Network Support

• Direct connections without a proxy.
• SOCKS4 proxy support.
• SOCKS4a proxy support.
• SOCKS5 proxy support.
• Authenticated SOCKS5 in user:password@host:port format.
• Local proxy list or proxy list loaded from a URL.
• Random or sequential proxy selection.
• Proxy retry and automatic proxy-list refresh settings.
• Optional DNS SBL checking with configurable DNS resolvers.

IMAP and SMTP Security

• Implicit TLS for SMTP port 465.
• Automatic STARTTLS for other SMTP ports when supported by the server.
• Compatibility fallback when an SMTP server does not provide STARTTLS.
• Implicit TLS for IMAP port 993.
• STARTTLS support for other IMAP ports.
• TLS certificate verification.
• TLS 1.2 or newer when an encrypted connection is used.

Available authentication and connection methods depend on the selected email provider. Some providers may require IMAP access to be enabled or an application password to be created.

Account Format

Accounts are imported through a simple text format:

email|password|smtp server|smtp port|smtp login method|imap server|imap port|imap login method

Example:

user@example.com|password|smtp.example.com|587|0|imap.example.com|993|0

A helper utility is included for combining separate IMAP and SMTP account lists into the required GoAutoResponder format.
