Why do my Mail accounts keeping going offline since I switched to comcast?

I recently switched to Comcast. The ougoing mail for my new comcast accounts goies on and offline constantly all the time. It doesn't happen for my .mac account. I've tried changing the port to 465 or 587 but that doesn't make any difference. any ideas?

You will need to call Comcast and ask them exactly what settings they require; I've had multiple problems with them which were finally resolved when he told me to start using port 25 (but mentioned that that is not available everywhere and/or not widely used or something like that). I used to have to delete the Mail .plist and set up Mail again and again to the point that I made screenshots of all settings windows so I could just copy them if needed. Here is a screenshot of my outgoing (smtp) settings:
Again, this was at the direction of Comcast tech support. I believe they also now have a web page with instructions for Mac.

Mail accounts keep going offline and then back on again

I am using Mail 4.4 on OS 10.6.6. I have 9 different email accounts in my inbox from 4 different domains. All the domains are hosted on a reseller account so they are all on the same server. Mail is scheduled to check mail every 5 minutes and each time alternating accounts go either on or offline. This behaviour also happens on my iphone 4 with IOS6 and ipad 2 with IOS5.
I am using the same setup and OS as I have been for the past year or so and it has been absolutely fine up until a few months ago. My ISP is being helpful and they have replicated the problem on one of their Macs but it doesn't happen on a PC. They are puzzled also.
I read somewhere that the mail app has a short time out where it takes the account offline if there is no response and that having all email accounts on the same server might cause this problem. Not sure if this is correct advice however.
I have turned off some of the accounts so that only 2 are in the inbox, its still happening but not as often. Anybody have any suggestions as its driving me mad.

My brother and mother are having the same problem. We all three are on SBC Yahoo! DSL and all share GoDaddy-based email addresses. I'm clearly on a different part of the SBC Network - as I have rarely had problems with mail accounts kicking me offline, whereas they have the same problem you do - accounts are random and inconsistent when they kick offline.
I've tried to research whether it's a GoDaddy, SBC or Mail issue. Thanks in advance!

My AOL account keeps going offline since I installed Yosemite

What setting may I alter, please, to get my AOL mail account back online. In my AOL Account settings, under outgoing mail servers, it states in parenthesis I am offline next to AOL.
Under Mailbox in the menu, there are only two options to take iCloud or AOL offline, but that doesn't make sense to me.
Thank you for your help.

TS3276 mail smtp accounts keep going offline

My mail sending accounts keep going offline. I am receiving mail ok but cannot send. I have double checked all the settings and all are OK. I have ensured that my OS (Lion) is updated but I cannot resolve this. Is there a simple fix out there? Many thanks

Try posting this in the 10.7 Mail forum. You'll get more help there.

Mail accounts keep going off line since Mountain Lion upgrade

My iCloud accounts keep going off line after a while. When Mail asks me if I want to take my accounts online (after pressing the exclamation triangle) nothing happens. The only way to get my accounts back online is to close and reopen Mail. Any thoughts?

It might be worth pointing out I get the error message "The server returned the error: The server “p04-imap.mail.me.com” cannot be contacted on port 993.".
I've tried having Use SSL checked and unchecked but it doesn't seem to help. The only thing that solves it is closing and reopening Mail.
Finally it would now appear that it only happens after the mac has been woken from sleep.

HT1515 why does my airport express keep going offline?

i use airport for air play but it keeps going into flashing amber light about every week. why?

I found on some non-Apple tech sites some interesting info. One guy was having the same exact issues and wrote a script to see what was going on between the Airport base station and the Airport Expresses. It appears that the two devices were having security verification issues and that is why the Airport Expresses get getting knocked offline. In other words, when they talk with each other they fail the security verification and the Airport Expresses go haywire.
So the solution is to turn off the security on both the Airport base station and the Airport Expresses through the Airport Utility. Then, on the Airport base station you check the option to create a closed network. In other words, your wi-fi network is now unprotected but it is not broadcasting to anyone that it is there. From then on, you will have to choose "other" on your laptops/iPads/iPhones/etc and type in your wi-fi network's name rather than just choosing your wi-fi network from a list of options.
I did this a few weeks back and I have had zero issues since the very moment I did the above steps. The network is 100% reliable and faster. No more rebooting. Is it a tad bit unprotected? Yes, but no one knows the network is there. If someone is smart enough to be looking for non-broadcasting wi-fi networks and finding yours, then they are sophisticated enough to defeat your normal security protocols anyway. Maybe if Apple ever decides to fix this problem, which appears they might not be interested in doing, then you could go back to normal security protocols. But until then, this works wonderfully. Give it a try and see.

All of my mail accounts keep going and staying offline

Any ideas. I've talked to two others who this is also happening...

I have been having the same problem for about the past 2 months using mail 4.4 on OS 10.6.6. Its been working fine for a couple of years without a hitch until now. I have about 10 different email addresses all hosted on the same reseller server. Each time there is a timed 'get mail' various accounts go offline and then come back online later, sometimes after a minute or so, some after an hour.
A similar thing is also happening on my iphone4 and ipad2 - 'mail server....... not responding'. This also seems to randomly alternate between various accounts.
My ISP has looked into it and cant find a problem but I think that this is because they cant replicate the problem. They suggested it might be a router/network issue but the problem still happens regardless of wifi being switched off. I have tried a Telnet test and all seems Ok.
Very frustrating as I sometimes have to wait for over an hour for an email to come in that is urgent.

Mac OS X Leopard Mail SMTP server keeps going offline and won't come on

My SMTP in mail on my email accounts keeps going offline and I can't work out how to get it working again. My internet connection is fine. I am receiving emails. I was able to send earlier on my business email account but now my .mac account has gone offline and then my business on went on me.
I only started using my business email account in mail today and loaded the account into mail. Does anyone have any answers for this as I can see there have been some other people who might have had a similar problem but I can't see any fixes?
I have deleted and reloaded both my .mac and work account a couple of times now and restarted my computer but still no good.
Can anyone help?

I have that offline mail smtp server when I try to send emails from work with my macbook. I've always been able to send emails away from home using the login and password in the smtp configurations. It's a real pain since I use one email account for work and personal business. I can receive email but cannot send any. Everytime I have to answer an email while I'm working, I have to go to the browser, go to my provider's mail page, login and send from there my emails.
Do we have the same problem?

Mail keeps going offline on MobileMe and my ISP's POP

Hi,
Just in the past 2 days my accounts keep going offline, If I bring them back online they instantly go offline again.
I opened the connection doctor and it says I am connected to the internet however in the details below it says it could not connect to his mobileme imap server or my 3 other pop servers.
I can get mail on my iPhone using the same Internet connection as my Mac.
This happens with wired and wireless connection.
A fix which works for 30 minutes or so is to disable all of my accounts in preferences and then save and then press enable again.
I spoke to Apple Care and they weren't much help.
Is there any other suggestions anybody can suggest? I am thinking of creating a temp account and importing my MBox's I don't know if this is a good idea though.
My MobileMe account is sitting at 670mb and all of my pop mail gets deleted and goes to 0mb as I run rules to transfer it to my MobileMe folders.
Please help!!

I have a similar though not identical issue with Mail - I have Comcast and Mail goes offline constantly - I reboot - reenter the port #'s and it may or may cure it - I sometimes wait and it fixes itself - When I go to Comcast web mail it's all there. It's just the Mail application - it's not a Comcast issue -
I will also receive prompts saying that the pop a/c is asking for a different port # than I've been told to use 110 for incoming and 587 for outgoing - no ssl checked - sometimes it almost seems like the numbers change on their own - I doubt that is happening and nobody will cooberate that but still it goes offline constantly - very frusrating - I am sure it has to do with Apple's security precautions in Mail -

Mail keeps going offline for no reason

During the course of a day Mail keeps going "Offline" and coming up with a dialogue box asking for me to re-enter my password. I've checked in my "account" and the information is still there so I manually have to click to go back "Online". But it repeats about every 15 minutes. Restarting the computer does not fix it and it's been happening for about 2 weeks now. Sometimes when I click to go back "Online" it doesn't happen straight away and I have to wait a few minutes. Very frustrating!!!. Sending mail is fine, it just affects receiving mail.

If Mail keeps asking for your password when retrieving mail, then it may very likely be that the password you entered has become corrupted in the Keychain. You should try this:
Open Keychain Access>Passwords and scroll through the list to find that specific entry and delete it; quit Keychain Access.
Restart Mail and enter your password again when it asks, and check the box to save it in the Keychain. If things work as expected, it will not ask you again unless your Keychain or an entry in it becomes corrupted again.

AIM account on Messages keep going offline

Hello,
I recently installed Mountain Lion on my iMac (iMac10,1) and added my AIM account to Messages.
When I am using Messages, my AIM account frequently goes offline by itself (and sometimes reconnects again).
I was wondering if this has happened to anyone else and if there is a fix.
Thank you,

Ive had this problem as well. I have four accounts two of which are yahoo accounts, 1 gmail, and 1 icloud. I have found that when you go to system preferences and then mail,contacts... and you click on details and retype your password it usually works. If that doesn't work though go to your email providers page and log in there and make sure your proxy settings are correct. Step two solved my issue. Hope this works for ya!

TS3276 All accounts keep going off line, quitting Mail fixes the issue

All accounts keep going off line, quitting Mail fixes the issue.
I have 3 Gmail, 1 hotmail and a yahoo. Al go off line with a little alert symbol next to them.
If I select take all accounts on line nothing happens.
Email delivery stops.
To fix this, I quit Mail and re launch it. That fixes it.
It's realy annoying.
Any ideas?

I have the same problem - it started when I upgraded to OS X 10.8
I thought subsequent releases may help, but I'm now on 10.8.2 and no joy.

The messages app in Mountain Lion keeps going offline

Hi, I am using ML on a 2010 MBP (13inch).
The message app has been configured with my Yahoo, Google Talk and iMessages accounts. The problem is that it keeps going offline. Oddly though, even when offline, I can get iMessages sent to me and it comes back online, however, my Gtalk and Yahoo friends don't see me when it auto goes offline. I tried enabling/disabling SSL in gtalk settings - did not help. I am sure its not my internet connection - I am now parallely using adium (after it kept going offline) and adium is always on for Google and Yahoo but the messages app keeps showing offline automatically (including message bar indication)

HI,
The other post I read seemed to indicate that the app "Closed" in the background when you were doing something in the foreground.
Crashed = the system tells you an App Unexpectedly Quit or there is a Crash log.
Crash Logs can be seen in Console then ~/Library/Logs/CrashReporter
Uploaded with Skitch!
You can of course navigate to your Home Folder/Library/Logs/CrashReporter and find the last Crash if there is one and it will launch Console when you try to open it.
At present I have not tried closing all the Messages windows and then letting the computer get to Sleep.
What do you have set in this spot ?
Uploaded with Skitch!
I am wondering if this is a normal function of the App so that anyone who has access to your computer can't instantly access your Messages partly as iMessages show so much "history" when a chat is reopened.
