I asked the mailbase people about their delivery/recipients ratios.
Their postmaster very kindly skimmed their logs and came up with these
figures for todays mail
1 : 96750
2 : 12570
3 : 4824
4 : 2309
5 : 1388
6 : 1061
7 : 704
8 : 637
9 : 305
10 : 262
11 : 301
12 : 237
13 : 114
14 : 176
15 : 95
16 : 104
17 : 85
18 : 104
19 : 145
20 : 71
21 : 65
22 : 75
23 : 20
24 : 58
25 : 7
26 : 8
27 : 8
28 : 2
29 : 6
30 : 33
31 : 5
===============
Total Recipients: 201816
Total SMTP sessions: 122529
Ratio: 1:1.65
I think this amount of bandwidth saving is well worth doing!
I also asked about addresses and distinct domain addresses:-
} Number of distinct domains : 27814
} Number of subscriptions : 186534
Going back to what started this long ago, I was wondering if there is some
halfway house we could use on the envelope sender address, so that each
separate SMTP envelope has a constructed sender address which would allow
easy determination of a group (maybe just one) of users that the anonymous
bounce message you receive is linked to.
This would need to be done within exim (rather than within the list
handler), and would somehow have to be passed to the transport (I guess)
as an option.... not sure how you would do it - I guess you would need a
command line option!
