sorry for stupidness - I really forgot to include *any* information... ok: this is a linux-system currently running under kernel2.4.16 cyrus-imapd is 2.0.16 (sasl: 1.5.27) sendmail is 8.12.1
a incoming mail is processed via sendmail which delivers to procmail, where - after prefiltering (attachments, viri, spam) a perlscript is called that checks the recipient against a sql-database and then applies some simple per_user-filters and finally calls 'deliver' to store the mail into the correct users mailbox and subfolder. perl is 5.6.1 this works quite fine. When heavy load is on the system, then this chain shows its many weaknesses, cause the backend of the sql-server cant serve that much clients and other things. This is why - as soon as I figured out how to deliver mails from perl directly to a imap-box - we will skip the procmail and deliver-part in the future and implement a pure perl-solution. But on the last load-test some different problem took place: lmtpd consumed 1,2GB memory and therefore made the system unusable. (the system went into 'permanent swapping' mode :) The problem was not reproduceable. On further tests the chains failed at its expected nodes, but lmtpd was behaving correctly (consuming 0,2% of cpu and 10-20MB) thnx, peter $cyradm -u cyrus localhost IMAP Password: localhost.localdomain> version name : Cyrus version : v2.0.16 vendor : Project Cyrus support-url: http://asg.web.cmu.edu/cyrus os : Linux os-version : 2.4.16 environment: Cyrus SASL 1.5.27 Sleepycat Software: Berkeley DB 3.2.9: (January 24, 2001) OpenSSL 0.9.6b 9 Jul 2001 $imtest -u cyrus localhost a ID NIL * ID ("name" "Cyrus" "version" "v2.0.16" "vendor" "Project Cyrus" "support-url" "http://asg.web.cmu.edu/cyrus"; "os" "Linux" "os-version" "2.4.16" "environment" "Cyrus SASL 1.5.27; Sleepycat Software: Berkeley DB 3.2.9: (January 24, 2001); OpenSSL 0.9.6b 9 Jul 2001") a OK Completed my configs: $ cat /etc/imapd.conf configdirectory: /data/imap/config partition-default: /data/imap/spool admins: cyrus pilsl srvtab: /data/imap/srvtab allowanonymouslogin: no sasl_pwcheck_method: PAM tls_cert_file: /data/imap/config/server.pem tls_key_file: /data/imap/config/server.pem ------------------- $ cat /etc/cyrus.conf # standard standalone server implementation START { # do not delete these entries! mboxlist cmd="ctl_mboxlist -r" deliver cmd="ctl_deliver -r" # this is only necessary if using idled for IMAP IDLE # idled cmd="idled" } # UNIX sockets start with a slash and are put into /var/imap/socket SERVICES { # add or remove based on preferences imap cmd="imapd" listen="imap" prefork=4 imaps cmd="imapd -s" listen="imaps" prefork=0 pop3 cmd="pop3d" listen="pop3" prefork=0 pop3s cmd="pop3d -s" listen="pop3s" prefork=0 sieve cmd="timsieved" listen="localhost:sieve" prefork=0 # at least one LMTP is required for delivery # lmtp cmd="lmtpd" listen="lmtp" prefork=1 lmtpunix cmd="lmtpd" listen="/data/imap/config/socket/lmtp" prefork=1 } EVENTS { # this is required checkpoint cmd="ctl_mboxlist -c" period=30 # this is only necessary if using duplicate delivery suppression delprune cmd="ctl_deliver -E 3" period=1440 } -- mag. peter pilsl phone: +43 676 3574035 fax : +43 676 3546512 email: [EMAIL PROTECTED] sms : [EMAIL PROTECTED] pgp-key available
