The email server tailored to b1gMail

Use b1gMail to unleash the full potential of your b1gMail-based email portal! b1gMailServer is a custom-made email server which has been optimized for use with b1gMail.

b1gMailServer contains POP3, IMAP and SMTP services which allow your users to access their email accounts with almost any email client application available. At the same time, the built-in SMTP server can be used as an MX server for your service which has been specifically optimized for b1gMail.

With modern features like IMAP push, support of the Sender Policy Framework (SPF), grey listing, AutoDiscover and AutoConfig, TLS encryption and more, your email system is well prepared for the future.

b1gMail account in Thunderbird

POP3, IMAP and SMTP access

With POP3, IMAP and SMTP access, you enable your users to synchronize their email accounts with almost any email client and mobile device available, including smartphones and tablets.

When using the IMAP protocol, all emails and the complete folder hierarchy of the account can be synchronized with the email client. Besides that, the email account can be synchronized among multiple devices, e.g. the user's desktop PC, notebook, smartphone and tablet. b1gMailServer's IMAP service supports IMAP push. Using IMAP push, smartphones can immediately notify the user once a new email arrives.

POP3, IMAP and SMTP access can be individually enabled or disabled for certain b1gMail user groups within the b1gMail ACP. This way, you can, for example, limit IMAP access to certain groups (e.g. active subscribers) only.

Autoconfig

AutoDiscover and AutoConfig

Thanks to integrated support for the AutoDiscover and AutoConfig protocols, configuring an email account is easy and does not require the knowledge of technical details like ports or server names.

In Outlook and Thunderbird, users can configure their accounts just by entering the email address and password. The email client then queries all the technical details required for setup directly from b1gMailServer.

b1gMailServer administration

Seamless integration with b1gMail

b1gMailServer can be administrated using a web-based frontend which is fully integrated into b1gMail's administration control panel.

The admin interface provides multitudinous configuration parameters to adapt b1gMailServer to your individual needs. With the built-in statistics and logs, you never lose track of the server's activity and important events.

b1gMailServer adds new parameters to the user group editor. For every user group, you can configure individual send frequency limits and permissions.
