Option 1 is not available because that's the standard behavior of IMAP. IMAP will ALWAYS download only the headers initially, and the message body only when actually opening the message. The whole point of IMAP is keeping the message stored on the server, so it doesn't "prefetch" messages. > I note that setting isn't available for an IMAP account - I wonder why > as I have a greater chance of downloading attachments automatically > without it... particularly since the option below also isn't available > in IMAP settings. > > Edit|Mail & Newsgroups Account Settings|<account>|To save disk space, do > not download: x Messages larger than __ KB Well, since email in IMAP is only *temporarily* stored on local disk, the "save disk space" justification is just not there.

No, you are right in that Seamonkey does fetch the attachments when the message is opened. I *thought* that it would fetch only the message body, leaving the attachment to be manually requested. I tested, and noticed that yes, the (undesirable) behavior you described was happening. So I went to Google to figure it out. There's a pretty complete writeup of the issue here: http://kb.mozillazine.org/Entire_message_fetched_when_opening_a_IMAP_message Summarizing: Yes, there are a few settings to fine-tune IMAP behavior. But they are hidden in about:config. The default values should work, though. By default, Thunderbird/Seamonkey will fetch only the headers, then the message body on message open, and then the attachments on request (that is, if you try to open/save the attachment). However, it will get the entire message (on message opening) if any of the following conditions is true: - If the IMAP folder is set to be locally cached; - If the attachments are rendered by the mail reader itself (like images, or TXT attachments) - If the junk mail controls are active for the account (because Seamonkey will fetch the entire message to be analyzed). -- MCBastos This message has been protected with the 2ROT13 algorithm.
