Mailhub

Mailhub is the ForgeOne service for professional email communication in Austria and the DACH region. This page helps customers classify common mail topics and provide the right information when support is needed.

What Mailhub is for

Mailhub supports email accounts, mailboxes, webmail, delivery, spam and virus filtering, and secure operation of mail domains. Typical topics include SPF, DKIM, DMARC, DNS, forwarding, aliases, shared mailboxes, password changes and vacation notices.

Which entry point should I use?

  • Mailhub / Roundcube is the customer entry point for email, password changes, filter rules, forwarding and vacation notices.
  • Sign in with the full mailbox email address as username.
  • If login does not work, first check the spelling of the email address and whether the password also fails in other email clients.

Setting up email clients

Use encrypted connections for new devices:

  • IMAP server: mailclient.forgeone.solutions
  • IMAP port: 993
  • IMAP security: SSL/TLS
  • SMTP server: mailclient.forgeone.solutions
  • SMTP port: 587
  • SMTP security: STARTTLS
  • Username: full email address
  • Password: Mailhub mailbox password

If your email client offers automatic setup, use autodiscovery first and then verify server name, port and encryption.

Changing your password

The password can be changed in Mailhub:

  • Open Mailhub.
  • Sign in with the full email address and current password.
  • Open settings.
  • Select password change.
  • Enter the current password and the new password.
  • Update the new password on all email clients on computers, phones and tablets.

A good password is unique, long and not reused for other services.

Filters, forwarding and vacation notices

Depending on the account, Mailhub can manage filter rules, forwarding and vacation notices. Check especially:

  • whether new rules apply only to new emails or also to existing messages,
  • whether forwarding should keep a copy in the mailbox,
  • whether a vacation notice has a start and end date,
  • whether external recipients should receive an automatic reply.

Classifying delivery issues

For delivery problems, these first questions help:

  • Does no email arrive at all, or only messages from specific senders?
  • Is only one email client affected, or webmail as well?
  • Is there a bounce message?
  • Does the message land in spam or quarantine?
  • Were DNS, SPF, DKIM or DMARC changed shortly before the issue?

Helpful information for support

For Mailhub issues, please provide:

  • affected email address,
  • time of the issue including time zone,
  • sender and recipient,
  • error message or bounce message,
  • email client or webmail used,
  • whether other users are affected.

First checks

  • Does login work at https://mailhub.forgeone.solutions?
  • Is only one email client affected, or webmail as well?
  • Is one address, one domain or several users affected?
  • Is there a concrete error message?
