Hey all, I had an older courier ispc3 system and converted it to dovecot for one of many reasons but one problem I didn run into is that ispc3 no longer tracks the mailbox traffic information (not that I really cared too much anyway). What makes it worse is that since it's not using procmail and instead using sieve, sieve has no way of writing to file (that I know of, possibly security reasons) so the ispconfig_mailsize files are no long updated. Using dovecot settings, I had written a sieve wrapper which will process the emails sizes and create/append the files upon receiving mail. I don't know how the new dovecot support works since 3.0.3 and how many people are using it. The sieve script and wrapper is still a bit quick patched up since I wrote it a while back but if there's interest, I'll release the code/howto. Tremors.
