Hi We really need some help resolving the slow email issue. I have been researching this for over 2 weeks now before calling our to RT_Users. I have searched all of the below,
http://wiki.bestpractical.com/ http://gossamer-threads.com/lists/rt/ http://www.google.com/ and much wider across the Internet. Almost given up!! ++Description: Overall there are no issues with email leaving RT - email reaches all destinations There are no issues raising tickets into the queue via email. Overall speed of moving around RT Web front end is fast / acceptable ++Issue: replying to a ticket takes up to 30 seconds to complete and sending the email in some cases up to 1 min. this is simply prohibitive to use in a professional setup. ++Other Issues: Squirrel Mail (Linux Web Mail) has the same issue, up to 30 seconds to send an email - no solution SSH to shell remotely same problem 30s - Now resolved by removing the DNS lookup: /etc/ssh/sshd_config [UseDNS no] SFTP - Slow 30 sec - fixed by line above Sendmail takes 30 sec to send an email from command line test an issue we have had with php apps for over a year - now resolved by : Edit the sendmail.cfg Was: # pass to name server to make hostname canonical R$* $| $* < @ $* > $* $: $2 < @ $[ $3 $] > $4 Now: # pass to name server to make hostname canonical #R$* $| $* < @ $* > $* $: $2 < @ $[ $3 $] > $4 OR sendmail.mc Add: FEATURE(`nocanonify')dnl then rebuiuld sendmail using m4 Sendmail now blistering fast. ++RT mail Configuration: Previously I was using sendmailpipe $MailCommand = 'sendmailpipe'; $SendmailArguments = "-oi -t"; $SendmailPath = "/usr/sbin/sendmail"; Now that I have confirmed that Sendmail is NOT the issue I am now using: $MailCommand = 'sendmailpipe'; #$SendmailArguments = "-oi -t"; $SendmailArguments = "-oi -ODeliveryMode=b -OErrorMode=m"; $SendmailPath = "/usr/sbin/sendmail"; Also have soft link: /etc/smrsh/rt-mailgate -> /opt/rt3/bin/rt-mailgate Note sure what else to test. The common denominator here is Apache Http So here is the conf entry for RT: [r...@caitanya conf]# diff httpd.conf httpd.conf.working.20101126 997,1015d996 < Alias /rt "/opt/rt3/share/html" < PerlModule Apache::DBI < PerlRequire /opt/rt3/bin/webmux.pl < <Directory /opt/rt3/share/html> < AllowOverride All < Options ExecCGI FollowSymLinks < <IfModule mod_access.c> < Order allow,deny < Allow from all < </IfModule> < </Directory> < < <Location /rt> < RewriteEngine On < RedirectMatch permanent (.*)/$ $1/index.html < AddDefaultCharset UTF-8 < SetHandler perl-script < PerlHandler RT::Mason < </Location> Appreciate any help that one can give. Its the only issue stopping us from moving RT from test environment to production. Naresh Maharaj, Hewitt & May (Shirtmakers) Ltd email: [email protected] web: http://www.hewittandmay.co.uk
