ah, but if you've got a really really big queue, and you want to produce a
listing, you can then use really basic unix tools like "grep" and "awk" to
manipulate it.
I'll save some bandwidth and post a trivial script here...
For example, get a one-message-per-line listing into a file called mq, grep it
for "hotmail.com" and pipe it into this script which thaws batches of mail;
I'll leave it as an exercise for the reader to make freezers, senders and
canceller versions.
Demonstration of shell hackery coming right up!
#!/bin/sh
# exim-thaw - thaw mail in batches of five, pipe in filtered queue listing
count=0
while read a b mailID1 c
do
read a b mailID2 c
read a b mailID3 c
read a b mailID4 c
read a b mailID5 c
echo "$count : thawing messages ${mailID1} ${mailID2} ${mailID3}
${mailI
D4} ${mailID5}"
/opt/exim/bin/exim -Mf ${mailID1} ${mailID2} ${mailID3} ${mailID4}
${mai
lID5}
count=`expr $count + 5`
done
