Spam sieve

The solution is very similar to Replacing antispam plugin with IMAPSieve,but instead of automatic learning it is supposed to store a copy of the message moved by user for further manual reviewing.In the example below when any user moves a message into or from Junk folder, a copy of the message is placed into report_ham or report_spam folder of spam@example.com mailbox respectively. When a message located in Junk folder replied to or forwarded, a copy of the message is placed into report_spam_reply folder.Requirementspigeonhole v0.4.14 or laterFoldersCreate report_ham, report_spam and report_spam_reply folders in the spam@example.com mailbox.Dovecot configuration20-imap.conf:protocol imap { mail_plugins = $mail_plugins imap_sieve}90-plugin.conf:plugin { sieve_plugins = sieve_imapsieve sieve_extprograms # From elsewhere to Spam folder or flag changed in Spam folder imapsieve_mailbox1_name = Junk imapsieve_mailbox1_causes = COPY FLAG imapsieve_mailbox1_before = file:/usr/local/etc/dovecot/sieve/report-spam.sieve # From Spam folder to elsewhere imapsieve_mailbox2_name = * imapsieve_mailbox2_from = Junk imapsieve_mailbox2_causes = COPY imapsieve_mailbox2_before = file:/usr/local/etc/dovecot/sieve/report-ham.sieve sieve_pipe_bin_dir = /usr/local/libexec/dovecot sieve_global_extensions = +vnd.dovecot.pipe}Sieve scripts/usr/local/etc/dovecot/sieve/report-spam.sieve:require ["vnd.dovecot.pipe", "copy", "imapsieve", "environment", "imap4flags"];if environment :is "imap.cause" "COPY" { pipe :copy "dovecot-lda" [ "-d", "spam@example.com", "-m", "report_spam" ];}# Catch replied or forwarded spamelsif anyof (allof (hasflag "\\Answered", environment :contains "imap.changedflags" "\\Answered"), allof (hasflag "$Forwarded", environment :contains "imap.changedflags" "$Forwarded")) { pipe :copy "dovecot-lda" [ "-d", "spam@example.com", "-m", "report_spam_reply" ];}/usr/local/etc/dovecot/sieve/report-ham.sieve:require ["vnd.dovecot.pipe", "copy", "imapsieve", "environment", "variables"];if environment :matches "imap.mailbox" "*" { set "mailbox" "${1}";}if string "${mailbox}" [ "Trash", "train_ham", "train_prob", "train_spam" ] { stop;}pipe :copy "dovecot-lda" [ "-d", "spam@example.com", "-m", "report_ham" ];Compile Sieve scripts:# sievec /usr/local/etc/dovecot/sieve/report-spam.sieve# sievec /usr/local/etc/dovecot/sieve/report-ham.sieveNow copies of e-mail messages should be placed in the report_ham

Synthetic material sieve frames, with no detachable pieces. All of this helps prevent food contamination. Efficient cleaning Arenit or Arenit Plus - choose between wooden or synthetic sieve frames The Arenit plansifter is fitted with wooden Nova sieve stacks. These are coated in resin with sturdy metal frame inserts. The sieve covers are glued to the metal frame inserts. The Arenit Plus comes with synthetic NovaTec sieve stacks, which offer a higher level of sanitation. These NovaTec stacks are available in one format of 730 mm x 730 mm. Billions of people come into contact with Bühler technologies to cover their basic needs for food and mobility every day. Our motto is creating “innovations for a better world.” Find out more about our key topics. The Arenit plansifter has a lightweight motor, designed to boost energy efficiency. You can adjust the swing weight to the settings of the sieve hub. The bearing assembly in the swing weight is also very robust and requires little maintenance. Our NovaTens sieve tensioner uses compressed air and rigid clamps to produce an even tension across the whole sieve. Designed for easy use, you need only a brief training course to use it.

Key benefits --> Efficient sieve cleaning The partitions in the compartment channels are well sealed. This prevents dust from spreading during sieving and grading and keeps the product pure. CKB0000011005--> --> High sifting throughput in a small space The Arenit has a net sieve surface of up to 84 m², with up to 26 Nova sieve compartments. CKB0000011004--> --> Sturdy and rigid frame A cast metal frame keeps the Arenit stable and robust for 24/7 operation.

CKB0000011006--> Highlight features High throughput Compact design for new plants and retrofits The Arenit plansifter is a key component in the flour production process. It is compact with a small footprint, reducing the amount of space you need for installation. This allows you to easily and quickly integrate the Arenit into new plants. It is also well-suited for retrofitting existing production lines. High sanitation Food safety and preventing food contamination The Arenit’s sifter compartments are insulated to prevent condensed water and damage to the product. The sifter compartments also have a stainless steel lining. The Arenit Plus has high-grade
