Looking at top 8 newest messages from my personnel email account: Newsletter Magazine Renwal Offer Ebook Update Notice Travel Deal of Week Sales Flyer with weekly specials Reply to forum thread Anouther Newsletter Custommer Service Response. Etc.
Hmm. All of these could really expire at 30 day mark except custommer service response in my opinion. Even if they expired at 365 days its better then sitting there forever. I can not honestly think of any reason to keep any of these past 30 days. If personnel messages never expire thats fine but all this other crap can AFAIC. On personnel messages perhaps give sender option of choosing option of 30days, 12months or never and default to never. Seems like new email clients default to leaving mail on server rather then downloading and deleting. Thats fine tell every email user is using 10G+ for email server space. Server space is not free and backups take time and even more space. Plus this all slows down POP3 etc as everytime you check email it must return a list of messages and when there are thousands of messages to look at that this can really load down a server. I imagine this would be like return receipts. Yeah its there but that does not mean all clients or servers are going to honor it.
