GersaMail

Mail stays with you

Mailboxes, calendar, contacts and files sit on your server. Access to correspondence does not depend on someone else's cloud plan or on the country of the data center.

One platform instead of a kit

Receiving and sending, webmail, calendar, phones, the panel, antispam and file exchange arrive in one installer. There is no need to join a separate web client, a separate calendar and a separate file exchange.

People work as they already do

A browser, Outlook and a phone connect to the same mailbox. Autodiscover tells the mail program the server address, so the administrator does not dictate ports to everyone.

One calendar for everyone

A meeting created in webmail is visible on the phone. Calendar and contacts live in one CalDAV service, Gersa Push — there is no second calendar database, and browser and phone do not drift apart.

Messages get delivered

The server signs outbound mail with DKIM. The panel shows ready SPF and DMARC text for the registrar and checks PTR and the address reputation. The signature is applied by the node that hands mail to the internet, so a message has one signature, not two.

A company signature without reminders

The server adds the mailbox or domain signature. It is the same in webmail and in the mail program: the employee does not forget the company block and does not put a personal version.

The administrator sees the whole mail system

Domains, mailboxes, aliases, groups and lists, quarantine, the delivery log, certificates, the cluster and an audit of actions — in one panel. A disputed message is found in the log, not in a user's retelling.

Mailboxes from the company directory

Active Directory and LDAP connect from the panel. A mailbox is created and matched to a directory account instead of being entered by hand a second time.

Spam stops before the mailbox

Rspamd scores every message, ClamAV checks attachments, and anything doubtful goes to quarantine. If policy requires Kaspersky, it is connected separately, on its own license.

Mail, meetings and files

• Its own webmail: messages, calendar and contacts
• Outlook over IMAP/SMTP or the GersaMail connector for Windows
• A phone via Gersa Push: ActiveSync, CalDAV and CardDAV
• Apple Mail — IMAP and the same calendar
• A file leaves as a link: the recipient does not need a mailbox

The day closes from the panel

• Domains, mailboxes, aliases, groups and lists
• The server checks the right to send as a group
• Quarantine, the message log and an audit of actions
• Ready DKIM, SPF and DMARC, and an address reputation check
• A Let's Encrypt or your own certificate, panel login with a limit on attempts

From one server to a cluster

• A single server combines the gateway and the mailbox store from the start
• The gateway accepts mail from the internet, the master stores mailboxes
• The reserve repeats the master and is not exposed to the internet itself
• The spare gateway holds the same domains and mailboxes: if the main one is silent, the queue goes there
• Built-in DNS can be turned on. The customer publishes records at the registrar
