Sorting mail with Maildrop or Procmail
- For sme9 and sme10
yum install smeserver-mailsorting --enablerepo=smecontribs
Allows a user to configure mail rules with the UserManager
Procmail or maildrop is used to process your email on the server. It follows user defined rules. Common uses are to sort mail into folders or forward selected email on to other email addresses. The rules that you define are executed as email arrives in your mailbox on the server, and are independent of your email client. If you sort to folders you will need to use a IMAP mail client to read them.
The panel shows a table of active rules and the order they are executed in. Each rule has links to modify or remove them.
A yes* in 'copy to' copies the email to your inbox
To forward an email to multiple addresses, place a space between them.
A user defines a pattern for emails that if matched, an action occurs.
The rule fields are in fact regular expressions compatible with egrep. As a result the above cited characters are interpreted as structure of the language. Refer to "man egrep" for correct syntax. As an example if you want to catch mails with the subject including "[mymailinglist]", your rule will be :
Also please note that that character "|" (pipe) is the default character used to separate fields in the internal database, so it is forbidden.
Use either procmail or maildrop
db configuration setprop qmail FilterType procmail db configuration setprop qmail FilterType maildrop db configuration delprop qmail FilterType [delete to disable]
If you want to bypass filtering for an individual user
db accounts setprop user MailFilter bypass db accounts delprop user MailFilter [delete to disable]
after any command
Any mail that passes through procmail or maildrop without matching a rule
is delivered according to the existing user setting.
ie. deliver locally, forward or both.
Only For SME9
Once Sieve enabled by the Contrib smeserver-dovecot-extras, filter rules defined in a user's ~/.procmailrc or ~/.mailfilter file are applied prior to the mail getting passed to dovecot-lda and Sieve. If you want to prohibit the use of Sieve for a determined User
db accounts setprop USERNAME Sieve disabled signal-event mailsorting-conf
Procmail will automatically delete duplicate email.
Maildrop has to be enabled at the command line
db processmail setprop USERNAME deldups yes signal-event mailsorting-conf
To enable for all users
db processmail setprop maildrop deldups yes signal-event mailsorting-conf
Create a global rule
It's possible just to use db commands, here is a subset of options
db processmail setprop 50001 pmGlobalRule action delete basis subject criterion xyz
50001: is the rule precedence
action: is either - sort delete forward
basis: match against this - headers Subject To From
criterion: using the text entered here - 'xyz'
For more flexibility create a fragment in templates-user, expand template as above
By design the mail user .procmailrc file is built from SME templates whenever a system update is performed. You can disable that action by enabling "geekmode", using the command below. With that done, you may write your own .procmailrc file and place it in the appropriate mail directory.
db accounts setprop USERNAME geekmode enabled
Geekmode implies you know what you are doing when creating a custom .procmailrc file.
Create a simple rule, eg Subject = xyz > forward to USER2
Send an email to USERNAME to match, check in USER2's inbox
