[Evolution] POP3 over SSL, error messages

[David Kvarnberg <evolution mellow net>]

Hi,
I've been using Evolution for quite some time now. I fetch mail via
pop3s (POP3 over SSL). Every once in a while I get the error message:

Error while 'Fetching Mail':
Could not connect to <my mail server> (port 995): Resource temporary
unavailable

Is there anything I can do to get rid of this message? It's quite
annoying, esp. since it grabs focus while I'm working on other stuff.
If I try fetching mail immediately after this error message, I usually
succeed. 

Outlook clients on my network fetch mail in the same way, but without
any warnings/error-messages ;)
