Currently Being ModeratedJun 20, 2009 5:33 PM (in response to PeteBell)Can anyone else reach any service (mail or web) on that machine in question? If no: don't believe that support guy.
If yes: is there any filtering or blocking software (e.g. firewall on your Mac or your router device) running?iMac C2D 20", 2.4 GHz, 2 GB, Mac OS X (10.5.7), MacBook Pro 13" / iMac G5 20" / original iPhone 8GB
Currently Being ModeratedJun 21, 2009 12:03 AM (in response to m.bode)Well, I can access them all fine through my iPhone.
No filtering or firewall blocking things my end.
I believe him, and he stayed up for hours into this morning trying to fix things for me!

Try also "telnet www.yourservernamehere.com 143". Are you able to connect?iMac C2D 20", 2.4 GHz, 2 GB, Mac OS X (10.5.7), MacBook Pro 13" / iMac G5 20" / original iPhone 8GB

I have several email accounts set up in Mail, and these include 3 or 4 POP ones and about 10 IMAP ones. Everything has been working well until today.
The POP ones still work well.
My mac.com address (IMAP / MobileMe) still works well.
But ALL my other IMAP accounts won't come online. They are stuck offline.
The support chap on my mail server assures me everything is working right that that end, but I cannot connect to my remote mailboxes.
I can’t vouch for the access problems where your website is concerned, but the multiple IMAP account issue is painfully familiar. For some odd reason, Mac Mail opens and “pings away” at the server with multiple connections per IMAP account-—even when you’re not actively checking for new mail. In my case, between two companies I run, there are 12 IMAP accounts. The second I launch Mail, those 12 accounts generated more than 75 access attempts in under ten seconds.
Needless to say, all the accounts fell off pretty fast.
My host company’s been a dream to work with, but is honest in telling me their servers aren’t set for this many multiple connection attempts from a single IP address (nor should they be). In trolling the threads here, I see this is a problem that’s existed in Mail since 2007, with no solution.
As much as it will turn my work process on its head, I’ve concluded the only solution is to revert back to POP accounts on everything, setting preferences up to keep things on the server for 30 days. Is this a pain? Oh yeah. But not having access to email at all while my poor host techs deal with my IP carpet bombing their servers is the lesser of two evils.

Currently Being ModeratedJun 26, 2009 2:38 PM (in response to PeteBell)Try going to another computer, preferable on another network (IE friends house), library. Or if you have a notebook Pete's coffee, and see if you can connect to your web service.
It seems very strange (Unless you changed something before this broke) that all your other services work fine, IE POP, and IMAP for .Mac, but the services provided by one service provider all stopped working at the same time.
What position was the chap that you spoke with? Was he Tier I, II, or Networking support. Seen it happen all the time where networking makes a change, Tier I, and II do not know about it.

Currently Being ModeratedJun 27, 2009 6:04 AM (in response to paperqueen)Thanks. The problem did indeed turn out to be the maximum number of concurrent connections allowed on the mail server. My host has upped the number and all seems well again at the moment. Thanks to everyone for their input.

Happy to help. Maybe we’ll get lucky and find this fixed in Snow Leopard (she says, hopefully).MacBook Pro, G4 PowerBook, G4 tower, iPod Touch, Mac OS X (10.5.7), Mac user since 1984
Currently Being ModeratedJul 11, 2009 10:12 AM (in response to paperqueen)A common problem as it seams, from some version of mac mail the mail client opens up several imap sessions when it connects to a server. Mozilla Thunderburd has a solution where one can limit the client to 1 session per imap folder, as far as I can see that sees both the server side and the client side, mac mail uses on my desktop these connections:
tcp4 0 0 172.17.3.9.57255 172.17.3.1.143 ESTABLISHED
tcp4 0 0 172.17.3.9.57253 172.17.3.1.143 ESTABLISHED

8 open and two more trying to open. My server had deafult courier-imap configured to 4 sessions per IP, increasing it to 11 made my client work with 2 imap folders.
Ask your supplier to increase this value in imapd.conf:
# Maximum number of connections to accept from the same IP address
I suggest the apple development team to make similar solution as Mozilla Thunderbird and make the client configurable according the concurrent sessions opened.mac mail and courier-imap, Mac OS X (10.5.7)
Currently Being ModeratedSep 23, 2009 7:49 AM (in response to PeteBell)Does anyone know if this was fixed in Snow Leopard?
I'm running into this problem as well. I had to have my hosting company increase concurrent connections to 35 to get 9 IMAP mail accounts to work. I've had to ping them every time it gets set back to some default, now they will only set it up to 20, can't blame them, but now I'm back to mail problems.
If SL fixes this, it may be time for an upgrade.MacBook, Mac OS X (10.5.8), Mail Version 3.6 (936)
Currently Being ModeratedOct 12, 2009 4:40 AM (in response to Richard Clem)I still have the problem in SL.
I've just stumbled across this discussion after having the problem in Leopard, and the problem remains in SL.
I only have a few email accounts so think contacting my service provider to increase my imap connections will help (something i was unaware of until I read this discussion)Macbook Pro, Mac OS X (10.6.1)
Currently Being ModeratedDec 6, 2009 5:10 AM (in response to globalgibbo)Hi there, I am running into the same problem here. Operating three IMAP accounts within Mail, one is my .me-Account, two are mailboxes with the same provider. They are not able or willing to increase my IMAP connections (can't blame them). Is anybody aware of another fix in Mail?MacBook 2.16GHz (white), Mac OS X (10.5.7)
