Dear Mark, dear listers,

I responded much too quickly that the issues with digest-mode were fixed. In reality they are not fixed, they reproduced and it is being a pain. In collaboration with our host, we have cleared, several times, the buffer, discarding repeteadly volumes (to get rid of potentially offending messages), reinitiate the mailman several times (in case it would be frozen somehow) and, still, is not sending any volume daily or when it reaches 250 kb, as it should, according to current settings. We have set new lists in the server and they seem to work normally, distributing volumes daily, as they should. The problems seems to be associated with these two lists, one with 600 other with 1700 registered members. Most of the 600 email addresses are also represented in the 1700 ones.

The only way we found it can work is by triggering, daily, manually, from administrative panel, the distribution of a new volume digest, if it is not empty. This works, nicely, and the digests are distributed normally and do not appear to have any problem. Of course, as you can imagine, this is suboptimal and it is not an acceptable solution.

Even though we use a dedicated web server this is administered by host and, thus, we have no root privileges and our administrator, at the hosting, is not able to provide any additional help beyond clearing volumes or reinitiating mailman nor it would allow us to access the mailman folder to explore for any additional problems. The found an email address they thought was causing some problems, although it is a standard email address used normally by his owner outside mailman context. Nonetheless we removed this address, but problems continued. Could it be that we have still, somewhere, an email address, someone that is registered in both lists for digest mode, triggering these troubles and limiting the distribution of volumes?

At hosting level they keep indicating that mailman is outdated, no longer maintained and that we should consider moving to other programs, like phplists, which I checked and doesn't do, at all, the same function as mailman. Phplist is for newsletter distributions not for email-based discussions, as mailman does nicely.

I'm happy with mailman, and I'd like to keep using it but when I come across these troubles, like now, where it seems nothing can be done to fix this no-digest-volume-dispatching it is really disappointing.

What else could I do? Thanks again for ideas or suggestions.

best regards

Lluis

the two large list are not sending any digest-mode, with the exact
same settings, even if I decrease the value to 256 or if I trigger
sending a new digest dispatch right now, which does not happen. I'm
totally amazed. I've seen the archives of mailman and, unfortunately,
the problems with digest-mode appear to be rather common, many reports
found, but not really solutions, at least, I could not find the one
that will fix my bug.


There is almost certainly a message or messages in the
lists/LISTNAME/digest.mbox files for these lists that is causing an
exception to be thrown in the scrubber in it's attempt to process the
digest.

Ask the hosting provider to look for relevant error messages and
tracebacks in Mailman's error log.

You may have to have the hosting provider just move the
lists/LISTNAME/digest.mbox files aside and abandon the current
accumulated digests if the hosting provider can't do anything more
selective to find and fix the offending messages.
