\"Mysza\"<\/a>Sometimes you need to remove some mail from queue or do other things in shell. For experienced administrators this is not a problem, but I decided to write some usable shell commands and scripts for less experienced users.<\/p>\n

Here are few commands to remove mail from Postfix queue. Don’t ask me why – just for example. This time i will describe it step by step. This is mail queue:<\/p>\n

# mailq\r\n-Queue ID- --Size-- ----Arrival Time---- -Sender\/Recipient-------\r\n571AAC45      48204 Tue Dec 21 07:52:39  MAILER-DAEMON\r\n                (connect to example.com[221.X.X.70]:25: Connection refused)\r\n                                         datadm@example.com\r\n...\r\n<\/code><\/pre>\n

\nLet’s choose only messages from MAILER-DAEMON:<\/p>\n
# mailq|grep MAILER-DAEMON\r\n571AAC45      48204 Tue Dec 21 07:52:39  MAILER-DAEMON\r\n5C0671838      4528 Mon Dec 20 15:19:35  MAILER-DAEMON\r\n806BF1FB0     12469 Mon Dec 20 00:38:55  MAILER-DAEMON\r\n2CDC81BDE     47643 Mon Dec 20 12:05:33  MAILER-DAEMON\r\n623E21AFE      4096 Mon Dec 20 13:16:59  MAILER-DAEMON\r\n682491647     11799 Wed Dec 22 06:18:43  MAILER-DAEMON\r\n...\r\n<\/code><\/pre>\n
Operations are done on Queue-ID, so we need to select only first column:<\/p>\n
# mailq|grep MAILER-DAEMON|cut -d\" \" -f1\r\n571AAC45\r\n5C0671838\r\n806BF1FB0\r\n2CDC81BDE\r\n623E21AFE\r\n682491647\r\n...\r\n<\/code><\/pre>\n
Now, send it to postsuper<\/code> command:<\/p>\n
# mailq|grep MAILER-DAEMON|grep ^5|cut -d\" \" -f1|postsuper -d -\r\npostsuper: 571AAC45: removed\r\npostsuper: 5C0671838: removed\r\npostsuper: Deleted: 2 messages\r\n<\/code><\/pre>\n
I limited scope to those, which begin with 5 (grep ^5<\/code>), to show that grep<\/code> and cut<\/code>, can be replaced with one gawk<\/code> (GNU awk) command:<\/p>\n
# mailq|gawk '\/MAILER-DAEMON\/ { print $1 }'|postsuper -d -\r\npostsuper: 806BF1FB0: removed\r\npostsuper: 2CDC81BDE: removed\r\npostsuper: 623E21AFE: removed\r\npostsuper: 682491647: removed\r\n...\r\n<\/code><\/pre>\n
If it happens that the argument list is too long, then you need to use xargs<\/code> command before postsuper<\/code>.<\/p>\n
# mailq|gawk '\/MAILER-DAEMON\/ { print $1 }'|xargs|postsuper -d <\/code><\/pre>\n
