Mail 2.1.3 Port Connection error after security update.

Question

I have 6 active email accounts that are normally checked by Apple Mail. After installing the most recent security update yesterday, 4 of the 6 accounts stopped connecting to their respective ports. Two of them are POP accounts (both gmail accounts on port 995), two are IMAP (ports 993 and 143), all four use SSL in the advanced settings. Of the two accounts that still work, one is an IMAP account (port 143), the other is a POP account (port 110), both without SSL. Firewall is on.
I get the error:
"There may be a problem with the mail server or network. Check the settings for account "account name" or try again.
The server error encountered was: The connection to the server "correct server" on port 995 timed out."
The error is the same for all four accounts, with their respective ports.
I have checked my server settings and verified that they are all correct. I can login to webmail for all of these accounts and read my mail without problems.
Mail Connection Doctor says:
"Could not connect to this POP server. Check your network connection and that you entered the correct information in the Accounts preferences. Also verify that the server supports SSL. If it does not, uncheck the "Use SSL" checkbox in the advanced tab of Account preferences."
All four accounts require use of SSL.
I have tested their connections on two different wireless modems and an ethernet connection to the same network as one of the wireless setups. No change.
I have tried turning off my firewall. No change.
I tried setting up one of my gmail accounts as an IMAP account instead of POP. This did not work either.
I have tried adding a Firewall Port connection for ports 995, 993, and 143 as both TCP and UDP numbers (independently and together). No change.
I have tried following these instructions from Mulder in response to another user's topic:
"1. Quit Mail if it's running.
2. Go to Home/Library/Caches/Mail and delete all the sub-folders within that one.
3. Go to Home/Library/Mail and delete this file:
• LSMap2
4. Restart Mail and see if it works."
No change.
Any other suggestions?

I did get some suggestions from this

thread, but still no email from those four accounts. Does anybody else have any suggestions?
I really do not want to have to resort to webmail and/or my iphone for my email needs.
