Cannot send email- Possible firewall issue

Hi all,
I have recently downloaded firefox, which was meant to replace safari on my macbook. Since doing this I have been having issues in sending emails from my aol accounts on mail.
Does anyone know how to rectify this so that I can send emails again as I need it for my business.
Thank you in advance.
Laura

I too am having trouble sending emails on my mac but can receive ok.
Sometimes I can send mail but most times it just times out. I have spoken to my service provider but they insist that it is something to do at my end.
I have recently installed a Apple Base station with modem attached. This has been a problem since I added this device. Before I used a D-link route which was ok for years until it died.
I have read several discussing that talk about changing the MTU settings on the mac using terminal. Surely this can not be the way? And to have to do it every time you log in sounds mad.
I set the MTU on the modem to 1431 when speaking with my service provider but this didn't make any changes.
Any ideas what I can do?

I talked with a tech today and he said I cloud is having problems which should be resolved shortly.
In the mean time I used the .me smtp server settings which allowed me to send mail.

I cannot send emails, only receive, after upgrade to Yosemite today, Apple should resolve this issue. Any help more than welcome. Thanks

BTW. I have seen posts suggesting age of Mac has an affect. Mine is MacBook Pro (Retina, Mid 2012)
The mail I am having problems send is Exchange and google mail. The google client I re-installed and this had no affect.

I have contacted three more people that made the upgrade and they have the same problem. My advise is not to upgrade until Apple solves the serious issue, I would hate to have to re-install Outlook...

I can send e-mails just fine with apple mail on yosemite...
Might not be a generic problem but rather a personal problem..
You should try find a fix rather than waiting on apple.
Hopefully somebody can help you out.
More than happy to help with your settings/preference pain... And compare mine with yours...
If you send some screenshots... I can send you my equivalent... So maybe you can figure it out.
Is it a gmail or icloud email acount? Can be of more help if it is.

Cannot send email via ActiveSync when user connect from Internet (Exchange 2010 SP3 RU5)

Hi All.
This is the first time I encounter this kind of issue, whenever user connect from the internet they cannot send email from their Phone or Windows Mail App, but they can retrieve email
But when they connect from Internal Network they can send email. I already test ActiveSync from internet using www.testexchangeconnectivity.com and it pass all tests.
I also check the Firewall and all the necessary ports already opened (we even open all ports) , the default TTL on the firewall 3600 second.
From what I read ActiveSync use some kind of HTTP POST or in MS terminology "PING" command, but still have no idea what kind of configuration that should be made to the Firewall so it can pass this "PING" command. Because from what I
see in Android Logcat the problem always related to this PING command
10-07 08:12:38.714 I/Exchange(31971): Interrupt with reason 1
10-07 08:12:38.714 I/Exchange(31971): Ping task ending with status: -1

Hi ronaldosy,
How about the work flow of Outlook or OWA on PC internally/externally?
If only phone has this issue, I suggest ask ActiveSync Forum for help so that you can get more professional suggestions. For your convenience:

Cannot send emails - connection to SMTP server timeout

I cannot send emails from my Thunderbird. Every time I try, an error message shows up saying that the connection to SMTP server has timed out:
"Sending of message failed.
The message could not be sent because the connection to SMTP server smtp.lineone.net timed out. Try again or contact your network administrator."
I have looked at many different possible solutions and tried them, but nothing seems to be working. I have tried several different ports, failed to send in Safe Mode with Networking and Thunderbird safe mode without add-ons and tried many different settings. I have ensured that the my settings on Thunderbird match the settings that my ISP recommends. My anti-virus software is not affecting it either. Maybe there is something I am missing but I would really appreciate any suggestions!
Here is some general info:
Mail provider: lineone
ISP: BT
Anti-virus software: AVG
OS: Windows Vista
Thunderbird version: 31.5.0

Hello @shredo,
Firstly, I would suggest reading this support article: https://support.mozilla.org/en-US/kb/cannot-send-messages
If that doesn't help, try some of these things (not sorted in any particular order):
*Test your connection in another network. There might just be some blocked ports in your router or conflict of some sort.
* Test your smtp settings in another email client (to ensure that they actually work). If it doesn't work, there might be some missmatch with the settings (even though you have ensured that they match), or some restriction by your router or something.
* Apparently, compacting your thunderbird folders might help with this issue (something to do with too many "deleted", that are still there) - http://kb.mozillazine.org/Thunderbird_:_Tips_:_Compacting_Folders
I hope this helps.

Cannot send emails on Yahoo mail. It works okay with Safari. I set default to Yahoo but still cannot send

Use MAC. Cannot send emails through Yahoo mail through Firefox but can send through Safari.
Also issue with Facebook. Using Firefox cannot sign out of account. Can sign out when using Safari.

Which security software (firewall, anti-virus) do you have?
Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps.
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe Mode start window or otherwise make changes.

Cannot Send Email From iMac

I cannot send email from any of my accounts via any of the asssociated servers, however I can receive mail through any of my accounts and servers. I haven't touched any of the preference setttings for any of the accounts so am really in the dark as to where to start to look for problems. I am using OS X 10.8.3.

Cannot send email from new iPad 2 or new iPhone 4s

I have a new ipad2 and a new iPhone 4s. I cannot send email from either. I had an iPad and an android before with no email issues. Phone is Sprint and ipad is Verizon. I have tried using my wifi and have tried turning wifi off. Nothing works. Please help.

I agree, unplug and replug your router, then reset your iPad by holding down the sleep and home buttons, ignore the red power down slider, and wait til you see the silver apple. let it reboot and then try your connection.
Chances are rebooting the router will help. You may also need to talk to cox. They may need to reset something on their end.

I cannot send email - error message as follows : 'The sender address (my email address) was rejected by the server smtp.tiscali.co.uk.' I can send email from other apple devices, and the email settings are identical. Any ideas?

For some reason I cannot send email - all was working fine, but now I get the following error message when I try to send email:
'The sender address (my email address) was rejected by the server smtp.tiscali.co.uk'
I can receive incoming mail ok and I can send email from other Apple devices. The problem seems confined to my Mac Book Pro.
Ant ideas?

Cannot send email user name or password is incorrect

I have an iPhone 3Gs with 6.1.6 iOS software and gmail. Until last week I could receive and send emails on my phone. Last week I tried to email a photo from my iPhone and received the following message "Cannot send email the user name or password is incorrect". About 30 minutes later I received an email message from google accounts with a sign-in attempt blocked message. Since then I have not been able to send an email from my phone. Every time I try to send an email I get the "User name or Password for Gmail is incorrect" - message. I changed passwords but that didn't help. I can receive emails on my phone but I can't send them. The only way I can send email is by clicking on the less secure apps button on the google accounts settings page.. Why do I get this message now and how can I get gmail working on my phone like it used to? If I delete my gmail account does it just remove it from the phone where the same account can be reinstalled or is it completely gone for good?

I can receive AOL mail on my iPhone but I cannot send email.

I can receive email for my AOL account on my iPhone but I cannot send email from the iPhone. I can send email OK from a computer. I have AT&T service.

razmee209 (and others in this community)... HELP!
I have the same issue - I can receive email on my iPhone, but cannot send messages.   Keep getting error message: (Cannot Send Mail - The user name or password for "SMTP:[email protected]" is incorrect
This issue occurred when I changed my AOL password.   I also updated my password on my iPhone.   After exploring this issue more deeply, it appears that my iPhone did not update my password for outgoing mail (as that are more "dots" in the password field for my outgoing server account, than for the incoming server passward that was just updated.
I am unable to change ANY of the information or settings in any of the outgoing mail server accounts - except only to toggle each account ON or OFF.   All other information is "greyed" out, and unavailable and inaccessible.
I know that if I could just change (or somehow sync) the outgoing password to match the new incoming password.
PLEASE HELP!!

Cannot send email just get a 'relaying' error messgae

Hi
Apologies if this has already been asked:-
i have an iphone 4 and have upgraded to the latest version of ios. But since then I cannot send emails from either my aol or hotmail account. I just get this error message:-
A copy has been placed in your Outbox. The recipient "*****@aol.com" was rejected by the server because it does not allow relaying.
Any ideas? Everything was fine before hand. I have tried deleting then reinstating my eamsil accounts both with wifi on and off and still no difference.
Please help its driving me MENTAL!!!!!!

re: not understanding instructions, it sounds like you have not enabled the Menu Bar.
In Thunderbird you will find life much easier when seeing all the toolbars.
Click on the menu icon - it has 3 bars.
Hover the mouse pointer over 'Options'
a new drop down appears, select 'Menu Bar'.
then you will see the Menu Bar above the tabs
It shows: 'File, Edit, View, Go, Message, Tools, Help.'
re: The mail server responded: 5.7.1 Missing or literal domains not allowed. Please verify that your email address is correct in your Mail preferences and try again.
Tools > Account Settings > Outgoing Server
you will only have the one verizon smtp
I looked at the information you provided in the other question.
Server name, port, authentication and connection security look ok.
What do you have in the 'User Name' ?
Do you have the full email address or just the first part before the @ ?
The other thing to check is the firewall settings in the Actiontec Router.
But this is not really a forum for dealing with your router.
you should find the model number somewhere on your Actiontec router.
There are different models, but sometimes the settings can be very similar.
you should be able to do a google search for your model.
I located this pdf for the GT701D model: see chapter 5.

Cannot send email with Mail app-..can't connect to AOL server anymore??

Up until today my MAIL app in my iMac let me use an email address that is from the AOL.com group (netscape.net)…I cannot send emails now because I can't get the computer to connect to the server. My iPad will….but not the desktop. I tried using a different server name; smtp.nestcape.net, which is the one I used in the iPad…but the iMac won't let me change it to that one..so back to the old smtp.aol.com……Still my MAIL app is not recognizing this or letting me connect!?!. I tried creating a new password at the wedpage of that email account.. successfully..but it has made no difference. I am stumped and have wasted half the day trying to deal with this. Anyone else have such an experience? HELP…PLEASE!

Thank you Eric for sending the links. Fortunately after I wrote this post…I don't know what happened but I filled in my mail preference settings for the umteenth time with my new email password and voila! It worked. For some reason however…now when I open the Mail App I do still get a prompt asking me if I want to use this server….and it is, of course, the one and only I have listed.!?!?! The thing that irritates me…is…that I had done NOTHING to cause a problem to begin with. I think my email account at aol (nestcape) may have been hacked and my password stolen or compromised in some way??...and perhaps that caused a glitch in my mail app??? I am no techy, but I should have started out with my intuition and changed the password first before going mental….When something like this happens it makes one feel so vulnerable.…I usually feel well secured with my lone iMac and now my new iPad…ANYWAY…thank tyou for addressing my issue and I have bookmarked those links…for future reference which I hope I never need. Hey..is that your kitty??? She is beeeooootiful!
Take care and again, thanx~ D
