I'm having problems using mail on one server. Any mail that seems to be generated seems to just get stuck in the outgoing mail queue. Most are sent from a php script but some may not be. The messages reports look like this: EB68F28D 444 Wed Mar 16 01:32:29 [email protected] (connect to 127.0.0.1[127.0.0.1]:10024: Connection refused) david@myother server.com all other messages also seem to be connection refused netstat -tap Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 localhost.localdo:10025 *:* LISTEN 3417/master tcp 0 0 *:mysql *:* LISTEN 8190/mysqld tcp 0 0 localhost.localdo:spamd *:* LISTEN 2730/spamd.pid tcp 0 0 *:sunrpc *:* LISTEN 2292/portmap tcp 0 0 *:ftp *:* LISTEN 14776/pure-ftpd (SE tcp 0 0 badbison.badbiso:domain *:* LISTEN 1640/mydns tcp 0 0 localhost.locald:domain *:* LISTEN 1640/mydns tcp 0 0 *:munin *:* LISTEN 3568/munin-node tcp 0 0 *:ssh *:* LISTEN 2502/sshd tcp 0 0 *:smtp *:* LISTEN 3417/master tcp 0 0 localhost.localdoma:671 *:* LISTEN 3463/famd tcp 0 0 localhost.localdo:45931 localhost.locald:sunrpc TIME_WAIT - tcp 0 0 localhost.localdo:39425 localhost.localdoma:671 TIME_WAIT - tcp 0 0 badbison.badbison:39470 badbison.co.uk:mysql TIME_WAIT - tcp 0 52 badbison.badbison.c:ssh 5acbb067.bb.sky.c:49447 ESTABLISHED 7097/0 tcp 0 0 badbison.badbison:36356 badbison.badbison:imap2 TIME_WAIT - tcp6 0 0 [::]:imaps [::]:* LISTEN 3331/couriertcpd tcp6 0 0 [::]op3s [::]:* LISTEN 3349/couriertcpd tcp6 0 0 [::]op3 [::]:* LISTEN 3337/couriertcpd tcp6 0 0 [::]:imap2 [::]:* LISTEN 3314/couriertcpd tcp6 0 0 [::]:http-alt [::]:* LISTEN 13764/apache2 tcp6 0 0 [::]:www [::]:* LISTEN 13764/apache2 tcp6 0 0 [::]:tproxy [::]:* LISTEN 13764/apache2 tcp6 0 0 [::]:ftp [::]:* LISTEN 14776/pure-ftpd (SE tcp6 0 0 localhost:domain [::]:* LISTEN 1640/mydns tcp6 0 0 [::]:ssh [::]:* LISTEN 2502/sshd tcp6 0 0 [::]:https [::]:* LISTEN 13764/apache2 tcp6 0 0 badbison.badbison.c:www 5acbb067.bb.sky.c:50248 TIME_WAIT - tcp6 0 0 badbison.badbison.c:www 5acbb067.bb.sky.c:50252 FIN_WAIT2 - uname -a Linux badbison.badbison.com 2.6.26-2-amd64 #1 SMP Tue Jan 25 05:59:43 UTC 2011 x86_64 GNU/Linux
Till, thank you for that. starting the service and flushing the mail queue worked. How did you know that was the issue? Was it just the lack of service for amavisd from the netstat command?
It was the error of the message in the mailqueue: connect to 127.0.0.1[127.0.0.1]:10024: Connection refused The normal email port is 25, but the error occured on port 10024, which is the port of the amavisd daemon.
Sadly I should have asked the question, why was amavisd offline to start with.... It is running now but mails are still getting caught in the queue with errors. When sending an email through roundcube, the server load went sky high and caused it to become completely unresponsive. The load went up beyond 50. It's now down to: Code: uptime 23:01:30 up 33 days, 21:28, 1 user, load average: 0.59, 0.31, 0.45 uptime 23:02:26 up 33 days, 21:29, 1 user, load average: 0.23, 0.26, 0.43 uptime 23:03:06 up 33 days, 21:29, 1 user, load average: 0.12, 0.22, 0.41 The queue looks like this: Code: C05392E 1495 Wed Mar 16 22:18:26 [email protected] (host 127.0.0.1[127.0.0.1] said: 451 4.5.0 Error in processing, id=21674-01, parts_decode_ext FAILED: file(1) utility (/usr/bin/file) error: run_command (open pipe): Can't fork at /usr/lib/perl/5.10/IO/File.pm line 66. at /usr/sbin/amavisd-new line 2892.

Thanks Till Increased ram to 1gb - and munin reports actually show some white space now. For info of others who ask about minimum spec and performance, the server with 512kb was running fine serving about 20 CMS sites but when mail services were added it needed the extra memory most probably for the intense amavisd service. The extra ram has coincidently made web serving MUCH faster. Full spec as below on a vds: 250 MHz processing reservation though no limit on bursts 1Gb of ram 1Gbps connectivity
