PHP 4.3.3 with_imap as opposed to 4.2.x

I just updated PHP to 4.3.3 from 4.2.2 . I use IMAP functionality for webmail, a client I wrote myself.
I noticed that I had to update {127.0.0.1:443}INBOX to {127.0.0.1:443/novalidate-cert}INBOX
(mind you, without putting it on 994/ssl), otherwise it would fail.
I know the cert is self-signed, but why check it on port 443???

Anyone got any ideas? It was just annoying to fix it in 6 different php scripts.

Thanks, as usual.
