Been exploring the new Atmail interface, and overall it's a nice update from Roundcube, with one major asterisk. That asterisk being that the webmail contents do not properly reflect the IMAP listing.
Say I opened Apple Mail and received 10 emails. I deleted eight, and kept two. If then I opened webmail, in Roundcube, those eight emails I deleted would appear ghosted (I could still view them if I wanted, though), and there was an option to compress the mailbox to accurately reflect the status of the IMAP server.
In Atmail, it appears if I've done nothing to the server (emails that have been deleted are not ghosted) and there's no way to compress the folder view. The only work around I've found is if I receive a new email and delete it, once the webapp refreshes, then it accurately reflects the proper state of the inbox.
If I'm missing a setting/function, please let me know. But if not, please find a way to introduce a compress feature, or simply figure out a way to have webmail accurately reflect the state of the IMAP server.
