BashEmailFOR DIRECTADMIN
A DirectAdmin spam filter that protects both sides of every mailbox.
Keep incoming spam, phishing and infected attachments away from customer inboxes, then contain outgoing abuse before one compromised sender damages the server's reputation. BashEmail filters mail on the DirectAdmin server you already operate, without changing MX records or sending customer messages through an outside gateway.
No MX or DNS change
Incoming and outgoing protection
Mail stays on your server
DirectAdmin email security for shared hosting
An unwanted message and a compromised sender create different risks.
Customers judge a mail service by what reaches the inbox. Repeated promotions, convincing phishing messages and harmful attachments quickly become support tickets. Yet the costliest incident may start quietly in the opposite direction when a stolen mailbox password or vulnerable website begins sending abuse through the server.
A DirectAdmin spam filter should protect both directions without treating every user alike. BashEmail lets the hosting team set the server-wide posture, make exceptions for a domain or mailbox and contain risky sending without disabling the customer's website, incoming mail or the rest of the hosting account.
On-server DirectAdmin spam filtering
Make one clear decision before each message reaches its destination.
BashEmail stays in the existing mail path. It applies the appropriate domain and mailbox policy, then sends wanted mail onward while suspicious messages follow the outcome selected by the administrator.

Set strictness where it belongs
Apply a different level to one domain or mailbox without forcing the same compromise on every DirectAdmin user.
Hold infected mail for review
Messages containing malware or viruses are kept safely instead of vanishing without an explanation.
Choose quarantine or Junk
Decide whether caught messages should be held centrally or delivered to the recipient's Junk folder.
One server, properly separated users
Reduce avoidable support work.Customers can find, preview, deliver or delete their own held messages without asking an administrator.
Keep every account private.A DirectAdmin user cannot search or act on mail belonging to a different hosting account.
Make retention predictable.The quarantine explains how much is held, how recent it is and when older mail will be removed automatically.
Give each DirectAdmin user control without exposing anyone else's mail.
Shared hosting depends on clear boundaries. BashEmail keeps quarantine access scoped to the domains, subdomains and mailboxes assigned to the current user. The hosting team retains the complete server view, while customers can resolve routine held-mail decisions for themselves.

Administrators can search and preview held mail across the server. Customers work only inside their own scope. Both can choose an action that simply resolves this message or one that also improves how similar mail is handled later.
Outgoing spam protection for DirectAdmin
Stop sending only.Incoming mail, websites, FTP and other hosting services remain available while outbound delivery is contained.
Protect every sending address.Reputation monitoring follows the addresses the server actually uses for delivery and warns when removal action is needed.
Keep the response visible.The hosting team can see why a sender entered watch, hold or suspension and when the automatic state will end.
Contain the sender without taking the customer offline.
A compromised mailbox or website is a security incident for the customer and a reputation incident for the hosting company. BashEmail watches outgoing activity, supports per-sender and per-domain rate limits, and gives legitimate higher-volume senders deliberate exceptions.
Automatic responses move through watch, hold and sending suspension. Every automatic action expires, so a temporary restriction is not left behind after the original risk has passed.

Keep customer mail on the DirectAdmin server where it already lives.
Cloud filtering services often require every domain to send incoming mail through an outside provider. BashEmail installs on the existing DirectAdmin server instead. MX records, DNS settings, mailboxes and the normal delivery route stay in place.
No third party becomes the temporary holder of customer messages or quarantine. The hosting company keeps operational control and customers continue using the mail service they already know.

See what BashEmail would do before it changes delivery.
A mail filter sits on a critical service. BashEmail is designed to enter production cautiously and leave the server in a predictable state.
Observe before enforcing
The initial installation holds nothing. Administrators review likely outcomes on their own traffic before enabling protection.
Fail open
If filtering is unavailable, mail continues rather than being deferred or bounced because of BashEmail.
Respect existing mail service
BashEmail adds protection without taking ownership of the customer's domains, mailboxes or delivery route.
Uninstall cleanly
Removal restores the previous filtering state, releases held mail and preserves what BashEmail learned for a later reinstall.

DirectAdmin spam filter questions
What hosting teams should know before enabling BashEmail.
What is BashEmail for DirectAdmin?
BashEmail is an on-server DirectAdmin spam filter for hosting companies. It filters incoming spam, phishing and malware, contains outgoing abuse, provides server-wide administration and gives users private access to held mail associated with their own domains.
Does the DirectAdmin spam filter require an MX change?
No. BashEmail runs on the existing DirectAdmin server and works with the current mail route. Customer domains do not need to point their MX records at an outside filtering gateway.
Does customer mail leave the server for inspection?
No. Filtering and quarantine remain on infrastructure operated by the hosting company. BashEmail is not a cloud mail relay and does not send customer messages to a third party for inspection.
Can different domains use different spam filter settings?
Yes. Strictness can be adjusted for an individual domain or mailbox, and allow or deny lists can represent trusted relationships and known unwanted sources without forcing the same policy on every user.
What happens to suspicious incoming mail?
The administrator chooses whether caught messages are held in quarantine or delivered to the recipient's Junk folder. Infected messages are held for review rather than silently discarded.
How does BashEmail handle outgoing spam?
BashEmail can move risky sending through watch, hold and sending-suspension stages. Rate limits support per-sender and per-domain overrides, and automatic actions expire instead of remaining in place indefinitely.
Does a sending suspension disable the DirectAdmin user?
No. The suspension applies to outgoing mail only. Incoming mail, websites, FTP and the rest of the hosting account remain available while the sending problem is investigated.
Can DirectAdmin users manage their own quarantine?
Yes. A user can preview, release and delete held mail for assigned domains, including bulk deletion and empty-all actions. Account boundaries prevent access to messages belonging to another user.
What happens if the filter is unavailable?
BashEmail is designed to fail open. Mail continues through the server rather than being stopped, deferred or bounced because the filtering service is unavailable.
