Hi,

as I wrote almost year ago in topic for old version of SimpleMail, E-mail account with lot of e-mails synchronizes slowly over IMAP.
This was present in the old version and is still present in version 2.86.8.

I have two e-mail accounts:

1. Gmail account where I use IMAP to access e-mail in Simple Mail. On that account I have almost 2000 e-mails remotely on Gmail server. Refresh of that e-mail account in Simple Mail takes very long, like 15 minutes, and during that time Firefox responds slowly. I have a feeling that Simple Mail each time downloads all those e-mails to compare if it already has them locally downloaded. Before the update of Simple Mail plugin this refresh took also 1-2 seconds, and if new e-mails were present they were downloaded by Simple Mail

2. Gmail account where I use IMAP to access e-mail in Simple Mail. On that account I usually have only few e-mails, since I also connect periodically with my other mail client that pulls the e-mails locally and doesn't leave them remotely on Gmail server. Refresh on that e-mail account in Simple Mail happens very quickly, maybe 1-2 seconds.
If I get many mails, and I don't download them locally with another e-mail client so they are no longer on Gmail servers, refresh in Simple Mail will also take longer and longer as number of mail grows, although I already have downloaded all those e-mails with Simple Mail.
Then if I download locally with another e-mail client all those e-mails, so they are no longer present on Gmail server and I try to refresh in Simple Mail refresh will again be done in 1-2 seconds.


I found a solution to this problem.
The solution was to modify overlay.js by removing the folowing piece of code from getMail function:

if (account.pop3.isImap) {
var messages = technalxs.simplemail.SimpleMailOverlay.storage.getAccountMessages(account.id);
var flag = "";
var folder = "inbox";
technalxs.simplemail.SimpleMailOverlay.SynchroMail(account, messages, folder, flag);
}

Now there's no more problem of long synchronization when a lot of e-mails are present on IMAP server.
