Apple Event: May 7th at 7 am PT

Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

imap synchronization on read/unread flag stopped with iOS 4.1, then 4.2

I use dreamhost imap on my mac and on my iphone. Until around the 4.1 timeframe there were no issues but around 4.1 on the iphone I noticed messages that I read on my mac are still marked as unread on my iPhone. I currently have something like 62 (out of 200 visible) unread messages on my iPhone. It's not predictable as far as I can tell which messages are unread. It's just a percentage of them.

Meanwhile my iPad had zero trouble.

Until the 4.2 update on the iPad. Now the iPad is exhibiting the exact same behavior as my iPhone, neither of which had trouble until the 4.1 timeframe.

gmail in imap mode works fine. However, clearly this is something that changed in the iphone software.

Anybody else seen this problem or have a fix/workaround? I've tried deleting my account and starting over. That works initially but quickly goes back.

BTW, it's happening to me and my wife and my friends also on dreamhost.

Macbook 2.4Ghz, Mac OS X (10.6)

Thanks for your email.

I just send another message to dreamhost to make sure they

(1) still believe their previous verdict; and

(2) are still working on deploying servers with the fix

I will let you know if I hear anything unsatisfactory.

Cheers!

Well dreamhost got back to me and said that Yes, they are still working on deploying upgraded dovecot servers.

Fingers crossed ...

@Lluis M

I encounter the same issue as yours.

I am my own email service provider and I replaced my server recently.

Since I have done that I have noticed that when I use the "reply" with a message from my iPhone then all my old messages truns immediately to unread.

If I write a new message instead of using "reply" the problem does no occurs.

I have also found out that if I deactivate SLL on the iPhone the problem disapears.

Changing the name of the mail server (mail.server.com instead of imap.server.com) does not solve the problem.

Can anybody confirm this is a bug ? ?

Here's what DH told me today:

According to our admins, an upgrade to the latest version of dovecot is

planned this year (2013)… Unfortunately, we do not have an ETA as to when the upgrade will be completed.

My take: We'll be living with this annoyance for awhile longer yet!
