iOS 4 Mail and self-signed certificates

I connect to a mail server that has a self-signed certificate. Under previous versions of iOS, this meant that I would have to allow the server connection once after a phone restore or update; however under iOS 4.2.1, I have to allow the certificate every time I access mail after the phone has been idle for the 'lock' time.

Can I get iOS 4.2.1 to trust the self-signed certificate the mail server uses?

MacPro Quad Core, G4 1000bT, MacBookPro, mini server, Mac OS X (10.6.5), 10.6.5 Server on MacPro

This is also an issue that I've been experiencing since upgrading last night. I called Apple Care, but as my phone is over the 90 days initial phone support period, the person I spoke to couldn't really help. She suggested to delete my accounts (I've got 5 with this issue) and recreate them, which I had done this morning, to no avail. She also suggested to create a new server and turn off SSL, but that didn't work either. Looks like I'm in for a trip to the Apple store. Whether that'll help is another story...

I seem to have found a resolution for this. I had a user name and password in my Outgoing Mail Server info, I have now removed these as they appear to be optional. You will probably still get the verification message a couple of times while setting up your accounts or modifying your settings, but once this is done, go back into Outgoing Mail Server and make sure SSL is turned off. I've recreated all my accounts, and so far, so good.

I am not really technical at all, so I am not sure I fully understand the subtlety of it al, but I haven't been getting any message at all since I've done this, either for incoming or outgoing mails, and believe me, I tried sending and receiving emails a few times from each of my accounts before posting on here. Whether this is the solution, I can't say, but it is currently working for me, and thought it might be helpful to others. It looks like it is saving me a trip to the Apple store, which is definitely a plus.

I am also affected by this. Both my iPhone 4 and my iPad 3G now display the certificate error "Cannot Verify Server Identity" when I wake the device up and send an email. I get it for both incoming and outgoing email.

I can click "Continue" and it works. I can click "Details" and "Accept" and it works. BUT I do not want to have to do this whenever I try to send mail after waking the device up. I know my mail server, I signed the certificates, and I am OK with its level of security. However, there seems to be no way to tell iOS that the certs are OK and safe to use and not bug me about. 😟

This is not good. :/

Hello all,
Can someone please explain (in non-techie terms) why we should or shouldn't use SSL when setting up an exchange account. I had it on, but was continually getting this same error after upgrading to 4.2.1. I just tried turning SSL off as suggested here (thanks Bruno), and I am no longer getting the error. Is my email going to be less secure now?
Thanks.
