Opera Mail does not fetch new messages from GMail

I have Opera Mail set up to download messages from my Gmail account, so I have a local backup of all my messages. It worked fine in the past, but now I checked again and it turns out it stopped loading new messages in the last few months.

In GMail POP is set up so it serves messages since 2004 (POP is enabled for all mail that has arrived since 9/14/04).
Authentication works because when I tell opera to check for new messages then it connects and I see its access in the activity log of GMail. (Also, I can send mail from Opera via Gmail without any problem).

The problem is Opera always says 'no new messages' when it connects to GMail. Why is that?

It's Opera 11.51

Not sure, but things you can try:

* Set the Mail Database Consistency Check Time to 0, save the change and restart Opera. Choose OK to perform the maintenance. The number will reset to a high number after the restart, so don't worry about that.

* Download the Opera installer and install Opera over the top of itself (upgrade to the same version) to repair any corrupted program files.

*. Close down Opera and delete autosave.win in the sessions folder.

* Log the connection and see if the log reveals anything odd about the connection.

* In the mail folder, in the pop3 folder, delete the uid file for the account. See accounts.ini to see what number the account is so you know what uid file to delete. This will make Opera refetch all messages that are on the server and new messages should then come in now problem.

Or, just do <http://operawiki.info/ImportFromBadMailFolder> to fix things.

If none of that helps, I'd look to see if any anti-virus software you have has an email scanner. If it does, disable the email scanner to see if it helps.

You might want to goto mail.google.com and disable the POP and then re-enable it.

You might to go into "mail and chat accounts" in Opera and purposely change the account's server settings. Then, retype and reset the correct settings.

On the incoming tab in the account properties, make sure "check every..." is set and "include this account when checking manually" is set. (These should be set since you get a "no new messages" notification, but make sure those settings are correct anyway.

Or, the first thing you can do is download the Opera installer and use the "standalone installation" option to install to a folder on your desktop. Then, setup the POP account in it (don't import). But, don't uncheck "leave messages on the server" and don't set "delete gmail's copy" at mail.google.com. If things work fine, then you know that it's just something messed up with your normal Opera profile (probably the mail folder). If things don't work fine, then I'd investigate into what's interfering with Opera.

Thanks for the suggestions.

Setting Mail Database Consistency Check Time to 0 didn't do anything. After a restart nothing happend, no check was offered.

Logging the connection did not reveal anything special, only that gmail returns a list of mail ids and Opera does not fetch any of them.

I deleted the uid file and it triggered fetching some messages, but apparently only old messages which were already in M2 were fetched again.

Disabling and reenabling POP in gmail had similar results.

I noticed that M2 shows some dates wrong. E.g. a mail from March 2008 is shown with the date March 2011. So something is really not right with Opera's mail database.

Maybe a clean reinstall will help, though I'm pretty disappointed I have to do that. Opera's internal mail handling implementation is not very high quality apparently.

You have to click "save" after you set it to 0. Then, when you shut down, Opera asks if you want it to perform maintenance. If you click ok, Opera will do so for a bit. Then, you just start back up. If you want to see what it found, you have to look at recovery.log in the mail folder.

Not sure what's up with that. But, on a side, make sure you time, date and time zone are correct. Them being off wouldn't cause that problem, but check anyway.

It should.

I did save it and Opera didn't ask me anything when I quit. I even tried setting it to 1 instead of 0, but nothing happened in this case either. After I set it to 1 I checked the value after a restart and it was set to -7.

You might want to check the permissions on your mail folder and all files in it. You should check permissions on both of Opera's profile folders too (the mail folder is in the one).
