I've had this problem for a while, maybe 6 months or so. It occurred now and then to begin with but now it's a permanent feature of my e-mail set up. With Apple Mail, I'd get the small warning triangle alongside 'Inbox' in the sidebar. Clicking on it would bring a dialog box offering the choice to take all accounts online. Again, to begin with, that did the trick, but now trying to take accounts online results in an alert box springs up with the message:
There may be a problem with the mail server or network. Verify the settings for account “zen.co.uk” or try again.
The server returned the error: Mail was unable to connect to server “mailhost.zen.co.uk” using SSL on port 995. Verify that this server supports SSL and that your account settings are correct.
I've been in touch with my ISP three times. They've had me check account settings (nothing wrong) and had me tinker with some of the advanced options (I can't now remember the details). The last time I was on the phone for 75 minutes and during that exchange they had me download Thunderbird. It seemed to do the trick, inasmuch as a load of emails appeared. Now, however, even Thunderbird just sits there 'Connecting to mailhost.zen.co.uk…'
Seemingly randomly, when returning to the machine at some later time emails have got through. The 'Get Mail'/'Get Messages' buttons don't work at all on Mail or Thunderbird.
I'm wondering whether there's a hitch with the modem. Could that prevent outgoing calls to the server? I'd like some new ideas before I try another phone call.
Where are the 'ports', as in port 995?
Anyone able to shed some light on possible causes for this? A possession requiring an exorcism perhaps?
