I think, I have found a problem in
exiscan !!!
(and also a solution(?))
In my tests with
exim for queueing emails
exiscan + sophos for scanning and dequeueing emails
I have seen, that in condition to working time of my tests
"younger" emails were transmitted earlier than "older" emails.
After 1h test time I've found delays of 45-55 minutes...the older emails
were still in the queue
???
What were to be seen at the (perl) code of exiscan:
In a SUPERLOOP part of the code exiscan
-reads the content of the email queue directory
-looks, if given emails aready in process (scanning)
-uses only non used email-Identifier (headerfile names) as an entry to
an assoziative array %IDs
-looks for all entries of this array and writes this entries to
the temporaray ID-array @tmpIDs (keys operation)
...here is the problem: I have tested it ... the keys operation
doesn't return the entries in alphabetic order
...After 1h I've found the oldest entries at the end of the temporaray
ID-array @tmpIDs ... >>> growing delays for older messages
I have now changed the perl code of exiscan:
old:
my @tmpIDs = keys %IDs;
to new:
my @tmpIDs = sort keys %IDs;
...new test:
After 1h I have only delays from 7-12 minutes (I think, it's ok ...my test
server is an older model...)
