As it is common for contributors to move between different email providers, email aliases (forwarding addresses) are provided to allow for a consistent email address to be given by a contributor. These are currently offered under two domains:
Any contributor to the KDE project is able to request a
kdemail.net address by submitting a ticket, including the initial destination address of the alias.
If a contributor wishes to request a
kde.org address, then they need either the support of two existing
kde.org address holders, or they need to be a member of the KDE e.V. (as an eV-member you are already supported by two persons in the past). Contributors who meet these requirements should file a ticket, mentioning the criteria they qualify under, the desired alias, and the initial destination address of the alias.
All changes to both kdemail.net and kde.org aliases should be made by filing a ticket. It is necessary (for authentication purposes) that the ticket is filed using a Identity account associated with the email alias in question.
Changes can include adding further destination addresses to your alias or removing existing destination addresses.
All email destined for kde.org and kdemail.net address is subject to both spam filtering and virus scanning. All mail which is determined to be definite spam or infected by malware will be rejected and not accepted for delivery.
For those contributors with either kde.org or kdemail.net aliases who are concerned about losing mail due to this can request that a copy of the filter logs for each day is sent to them by filing a ticket.
In certain instances, contributors may find that mail sent via their regular mail provider does not arrive at its destination, or cannot access their regular provider due to restrictive networks. In this case, contributors can try sending their email through mail.kde.org, the primary KDE email server. As an additional benefit, email sent via mail.kde.org from a kde.org address will be signed using DKIM, allowing the recipient to verify the email is legitimate.
In 2018 the mail server moved host from postbox.kde.org to letterbox.kde.org, however it is recommended that people use the canonical hostname mail.kde.org in their settings for SMTP as that will point to the correct host even if it changes again
You should use your Identity username and password to authenticate. You will also need to file a ticket asking for your account to be provisioned with the rights to send email through mail.kde.org
The following details should work in most email clients.
Host Name: mail.kde.org Port: 465 Connection Security: SASL/TLS Authentication: PLAIN
Host Name: mail.kde.org Port: 587 Connection Security: STARTTLS Authentication: PLAIN
