Version 1.703 ​

Released: 2026-06-01

Support for Ubuntu 26.04 LTS new ​

This release of DirectAdmin starts supporting the latest Ubuntu 26.04 LTS systems.

‼️ More secure outgoing email delivery new ​

The Exim configuration is updated to use a more secure email delivery mode for outgoing emails. When outgoing email is being routed, Exim will check the MX records for the destination domain even if this domain is configured as local on the server. If MX records point back to the server, the local mail delivery will be performed. If MX records point to an external server, then email will be delivered over SMTP.

Key benefits of this change:

  • Protection from email hijacking. If some user adds a popular domain like gmail.com or proton.me as his own domain, he will not be able to hijack outgoing emails for these domains that are being sent by other users on the same server.
  • Correct routing when MX proxy is being used. If the domain owner is using an external mail filtering service, his domain MX records will point to the service provider. After email is checked by the service provider it will be delivered to the DirectAdmin server. Emails from one user on the server to another user on the same server would get routed to the external service provider.

This new feature is controlled with the FORCED_MX_DNS_CHECK macro. It is enabled by default but can be disabled by setting this macro to the value no.

Examples:

sh
# Disable strict MX checking (insecure):
sed -i '/^FORCED_MX_DNS_CHECK /d' /etc/exim.variables.conf.custom
echo 'FORCED_MX_DNS_CHECK = no' >> /etc/exim.variables.conf.custom
da build exim_conf

# Restore strict MX checking
sed -i '/^FORCED_MX_DNS_CHECK /d' /etc/exim.variables.conf.custom
da build exim_conf

Flexible Exim configuration for not counting local-to-local emails update ​

Starting with DirectAdmin version 1.702, the Exim mail server configuration is updated to count all emails (including emails delivered locally) into the email send limit.

This release adds a new Exim configuration macro SEND_LIMIT_COUNT_RECIPIENTS, that allows selecting which recipients are counted in the email send limit and which are not. This option allows restoring the old Exim behaviour of not counting emails that will be delivered to the same server.

Default macro definition is SEND_LIMIT_COUNT_RECIPIENTS = $recipients_list. This means all recipients must be counted. Examples for different behaviour:

sh
# Do not count emails where sender and recipient address is from the same
# domain:
sed -i '/^SEND_LIMIT_COUNT_RECIPIENTS /d' /etc/exim.variables.conf.custom
echo 'SEND_LIMIT_COUNT_RECIPIENTS = ${filter{$recipients_list}{ !eq{${domain:$item}}{$sender_address_domain} }}' >> /etc/exim.variables.conf.custom
da build exim_conf


# Backwards compatibility mode, do not count mails that will be delivered
# locally:
sed -i '/^SEND_LIMIT_COUNT_RECIPIENTS /d' /etc/exim.variables.conf.custom
echo 'SEND_LIMIT_COUNT_RECIPIENTS = ${filter{$recipients_list}{ !match_domain{${domain:$item}}{+local_domains} }}' >> /etc/exim.variables.conf.custom
da build exim_conf
