Hi folks,
Hi,
I've run into an apparent limit in size - we send newsletters through one of our lists, and they can get large. One in particular runs over 20MB, and I get an error on the held messages page trying to process it.
I'm guessing that you are aware of the Maximum length (max_message_size) setting on the General Options page.
Remember that Base64 attachments become 4/3s their size. So a 20 MB file attachment becomes ~27 MB of Base64 encoded content.
Also remember that the MTA's maximum message size will add any headers and body content onto the size. So I'm guessing you want to be able to support 30 MB email messages. This should be easily doable. Even if some people (myself included) don't like it.
Currently we have version 2.1.20, I know there are updates but not if they address this limit or if there's some other fix.
I'm guessing that this is a Mailman and / or MTA configuration issue.
The fact that the message makes it into Mailman tells me that the MTA can handle the attachment. I wonder if simply raising the Maximum length (max_message_size) might allow the message to pass normally.
I don't know what to think about the pending moderator requests / hold page's behavior. I'll defer to other more knowledgeable people on the mailing list.
