Capmail - IMAP mail built into Dolibarr 2.0.6

Overview

In most companies, mail is handled in a mail program while customers live in Dolibarr. You copy an address by hand, look for the quote a message answers, forward the attachment yourself. Capmail brings your emails inside Dolibarr: your IMAP mailboxes, your replies, and every email linked to the right thirdparty, the right project, the right proposal.

Capmail in its own window

Capmail opens in a dedicated window, without the Dolibarr menus. All the room goes to the mail: message list, reading pane and actions side by side. Keep it open all day, next to your other windows or on a second screen, while you work in Dolibarr.

• Installable as an app: from Chrome or Edge, Capmail joins the applications menu of the computer and opens straight into its own window, with no address bar.
• Fullscreen reading: one key (f) hides the list and the action panel to keep only the message, another (Esc) brings them back.
• Keyboard shortcuts for everything you do daily: reply, archive, mark read or unread, star, spam, move to the next message.
• Comfortable writing: built-in rich text editor, reply templates, attachments, choice of the sending mailbox, reply, reply all, and forward with the original attachments.
• Resizable columns, whose width is remembered on the computer, and a compact mode to show more messages.

Mail that files itself

• Automatic link to the thirdparty: the sender is recognised from the Dolibarr thirdparties and contacts.
• Replies to your proposals, orders and invoices: when a customer answers a document sent from Dolibarr, the reply is linked to that document and shows in its "Linked objects" block.
• Conversation threads: messages of the same exchange are grouped, and linking a thirdparty applies to the whole thread.
• Automatic filters on incoming mail: tag, archive, forward, auto-reply, notify a colleague, create a ticket, a thirdparty or a project. A simulation shows the matching messages before you save the rule.
• Tags, shared or personal, with colours and keyboard shortcuts.
• Snooze: a message disappears until the date you choose, then comes back at the top of the list.

From email to customer, in one click

• Create a thirdparty, a contact, a project or a ticket from a message, with the fields prefilled.
• Data extraction: phone numbers, company registration number, address and company name are spotted in the message and offered to complete the thirdparty card.
• Extraction templates for the contact forms of your website (Contact Form 7, Wix...): each form field lands in the right Dolibarr field.
• Duplicate detection by address, phone, registration number or similar name, so the same customer is never created twice.
• Attachments copied to the linked project, proposal or invoice.
• A Capmail tab on every thirdparty card shows the complete history of exchanges.

Several mailboxes, one team

• As many IMAP mailboxes as you need: contact, sales, support, personal mailboxes.
• Rights matrix: for each user and each mailbox, read only or read and send.
• SMTP server per mailbox, with a custom sender address. Mails sent from Dolibarr proposals, orders and invoices can go out through a Capmail mailbox and are copied into its "Sent" folder.
• Two-way synchronisation with the server: read or unread, star, archive, spam. Markers are compatible with Thunderbird, so you can keep your usual client alongside.
• IMAP folder detection and repair, tested with OVH, Free, Gmail and Dovecot.

Security

• HTML messages are displayed in an isolated frame: no script contained in an email ever runs.
• Mailbox passwords encrypted in the database.
• Delete permission separate from read permission, personal mailboxes invisible to other users.

Languages

Interface available in French, English, German, Spanish, Italian, Dutch and Brazilian Portuguese.

Try it

A demo filled with sample emails opens in less than 20 seconds on dolitest.fr/capmail.

Requirements

• Dolibarr 18.0 or higher, PHP 8.0 or higher
• One or more mailboxes reachable over IMAP with a login and a password (an app password for Gmail)
• Outlook.com and Microsoft 365 are not supported: Microsoft only accepts OAuth2 authentication for IMAP. Proton Mail offers no direct IMAP access.

Every feature is documented online (in French): doc.cap-rel.fr/capmail

Support

Support goes through our support form, not through the comments on this sheet.

Support is not free. You want competent people on the other side: it is fair that they are paid for that time. The price shown covers the module and its updates. It covers neither installing nor configuring your Dolibarr, nor training your teams, nor specific developments, nor investigating an environment we do not host.

A reproducible bug in the module is fixed at no charge, as part of the updates above.

Before buying

• Check the Dolibarr and PHP versions stated at the top of this sheet: beyond them, the module is not tested
• Modules are deployed from Home > Setup > Modules > Deploy an external module, which requires an active custom directory on your installation
• When a module relies on an online service, the subscription to that service is separate from buying the module, and is stated above
