Mac Mail 7.3 receives but won't send on iMac running OS X 10.9.5

My spouse has an  iMac (Intel) running OS X 10.9.5 and Mail 7.3 has suddenly stopped sending email. It receives just fine. I also have an iMac (slightly larger) running the same software and I can send just fine. We are both using comcast.net. I've repaired permissions. Reset the routers and everything, but it still won't work. We can both send from our iPads and iPhones.

  • TS3276 My Mac is able to receive but not to send email

    Anyone please help. My Mac is able to receive but not to sen emails. I have tried backing up my emails, deleting my account on outlook and creating a new one, but, I continue having the same problem.

    What were the results of taking the pertinent steps in the support article?

  • Imac mail receives, but won't send

    I can receive from my acounts, but none will send.
    When I use the exact same settings in Entourage it works fine...but imail should work, no?

    Perhaps you need to recheck your settings to make sure they're configured correctly. This site show the proceedure quite clearly (with screen pics) http://www.cit.cornell.edu/helpdesk/mac/email/osxmailapp.html

  • Mail receives but won't send. Why?

    Error message says something to do with outgoing mail server (SMTP) having a problem or being incorrect. I have made no changes to settings nor have I upgraded or changed my Apple Mail.
    Does this have anything to do with the discontinuation of MobileMe? My email address I'm using is [email protected] .
    This problem was intermittent, but now it seems to be steady and continuous.

    Hello Earnie, I believe it is MobileMe being discontinued.
    Do not delete the old account yet. sign up for an iCloud account if you haven't.
    I understand .mac mail will still come through. Do not delete the old account yet.
    You cannot use .mac or MobileMe as type of Account, you have to choose IMAP when setting up, otherwise Mail is hard coded to change imap.mail.me.com to mail.me.com & smtp.mail.me.com to smtp.me.com, no matter what you try to enter.
    iCloud Mail setup, do not choose .mac or MobileMe as type, but choose IMAP...
    On second step where it asks "Description", it has to be a unique name, but you can still use your email address.
    IMAP (Incoming Mail Server) information:
              •          Server name: imap.mail.me.com
              •          SSL Required: Yes
              •          Port: 993
              •          Username: [email protected] (use your @me.com address from your iCloud account)
              •          Password: Your iCloud password
    SMTP (outgoing mail server) information:
              •          Server name: smtp.mail.me.com
              •          SSL Required: Yes
              •          Port: 587
              •          SMTP Authentication Required: Yes
              •          Username: [email protected] (use your @me.com address from your iCloud account)
              •          Password: Your iCloud password
    Also, you must upgrade your password to meet the new criteria:  8 characters, including upper and lower case and numbers.  If you have an older password that does not meet these criteria, when you try to setup mail on your mac, using all of the IMAP criteria listed above, it will still give a server error message.  Go to   http://appleid.apple.com         then follow directions to change your password, then go back to setting up your mail using the IMAP instructions above.

  • Apple mail receives, but won't send

    This is my last resort.  I've double-checked with my provider and all is ok on their end.  I have deleted settings and set them up as per their recommendations several times to no avail.  I can receive emails, but will not send and consistently get warnings about various things such as  the password is invalid, there's an invalid certificate or just that it can't connect.  The strange thing is, it all works fine on both my iPad and iPhone.
    I've tried several searches on the community forum and noticed several problems that were similar.  I hope someone has an answer that relates to this problem in regard to Yosemite.
    Thanks (fingers crossed).

  • IPhone email (one acct dead, other receives but won't send)

    I usually use Entourage, so I set up email in Mac Mail since that's the program iPhone reads from, correct? I have two email addresses, both with same provider (our own website via Hostway) and I receive and send both accounts fine in MacMail. On the iPhone however, I'm getting email for only one of the two accounts. And for that one that i can receive email from, I can't send to.
    I am used to the SMTP settings, but if I change it on the phone won't it just override it the next time it syncs with MacMail, which works fine?
    I've tried to look through other threads but I didn't see anything for this specific problem.
    thanks

    The iPhone only reads settings from mail.app if that option is checked in iTunes under the info tab when the iPhone is connected. You can set up the email on the phone independent of what is on your computer. Are these pop accounts, and what type of error do you receive for the account that can't receive email? And for the account that can't send, what errors are you receiving? A common problem is that the outgoing mail server for most ISPs can only be used when on that ISPs network without authentication. If your ISPs smtp server does not allow authentication from other networks, you'll have to use another smtp server for the outgoing email.
    In my case, my cable internet provider's email is received fine, but I cannot send email from that account using their smtp server (either on the phone or my MBP). So I have that account set to use a gmail smtp server instead so it can send email from any network.

  • Will receive, but won't send pics...

    Hi everyone! I'm hoing someone can help me with this issue cause it is infuriating! I can receive MMS pic messages, but I cannot send them... whether I take the pic myself and try to send it or whether I receive a pic and try to forward it, it will not send either way! I've had the problem of not being able to send or receive MMS messages in the past, and I took out my battery without shutting my phone off and that seemed to do the trick, but I tried that this time and it didn't work! I'm getting extremly frustrated so if anyone has any ideas on how I can fix this I'd be so greatful to hear your input! Thanks in advance for your help! -Gina

    Hi and welcome to the forums!
    Well the battery pull is always a good first step.!
    Are you able to tell what size message is guaranteed to fail, or is it random?
    View the size of an MMS message before sending it
    1. In an MMS message, press the Menu key.
    2. Click Options.
    The Estimated Size field displays the size of the MMS message
    KB13667Unable to send photos in MMS message
    Make sure you have set your camera options so you can reduce the size of the picture.
    I would also make sure that you resend your service books.

  • Mac mail 7.3 receiving but not sending

    Hello everyone,
    I have been stuggling with this problem for three days now.  I set up a new e-mail account (for a new job) and the new account will receive fine but not send.  Here is the general set of steps that I followed:
    *  Used IMAP unsecured - smtp port 25.  Failed due to port blocking
    *  Used IMAP unsecured - smtp port 587.  Works on other servers but this one not.
    *  Used IMAP and smtp secured with SSL - smtp port 465.  Failed.
    The last one is what I believe I should be using.  I get the standard "Could not connect to this SMTP server..." message on connection doctor, and all I get from the log is:
    INITIATING CONNECTION Jun 10 11:04:13.633 host:vps2955.inmotionhosting.com -- port:465 -- socket:0x0 -- thread:0x608002468c00
    CONNECTED Jun 10 11:04:14.278 [kCFStreamSocketSecurityLevelNone] -- host:vps2955.inmotionhosting.com -- port:465 -- socket:0x600000ad8d40 -- thread:0x608002468c00
    With no "READ" or "WROTE" messages or anything else.  The "kCFStreamSocketSecurityLevelNone" seems odd, but I've seen that elsewhere.  I've also tried:
    * Turning off SSL and using 465 - failed
    * Deleting all related keychain items - no effect (after accepting the cert)
    * Running keychain first aid - no problems
    I contact inmotion hosting and they said my settings all look right.  They can probe further, but I need to coordinate with my boss to get permissions for them to do that (maybe later today).
    One additional thing - using network utility I am able to see port 465 on this server as expected.
    I'm at a loss.  I've set up many, many e-mail accounts in the past and this is the first time I have ever had these sorts of problems.  Help!!!

    Under no circumstances should you ever change the trust settings of any SSL certificate, unless you created it yourself. That's just about the most dangerous thing you can do with a computer.
    Back up all data, then take each of the following steps that you haven't already taken. Stop when the problem is resolved.
    Step 1
    From the menu bar, select
     ▹ System Preferences... ▹ Date & Time
    Select the Time Zone tab in the preference pane that opens and check that the time zone matches your location. Then select the Date & Time tab. Check that the data and time shown (including the year) are correct, and correct them if not.
    Check the box marked
    Set date and time automatically
    if it's not already checked, and select one of the Apple time servers from the menu next to it.
    Step 2
    Triple-click anywhere in the line below on this page to select it:
    /System/Library/Keychains/SystemCACertificates.keychain
    Right-click or control-click the highlighted line and select
    Services ▹ Show Info
    from the contextual menu.* An Info dialog should open. The dialog should show "You can only read" in the Sharing & Permissions section.
    Repeat with this line:
    /System/Library/Keychains/SystemRootCertificates.keychain
    If instead of the Info dialog, you get a message that either file can't be found, reinstall OS X.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. Open a TextEdit window and paste into it by pressing command-V. Select the line you just pasted and continue as above.
    Step 3
    Launch the Keychain Access application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
    In the upper left corner of the window, you should see a list headed Keychains. If not, click the button in the lower left corner that looks like a triangle inside a square.
    In the Keychains list, there should be items named System and System Roots. If not, select
    File ▹ Add Keychain
    from the menu bar and add the following items:
    /Library/Keychains/System.keychain
    /System/Library/Keychains/SystemRootCertificates.keychain
    From the Category list in the lower left corner of the window, select Certificates. Look carefully at the list of certificates in the right side of the window. If any of them has a a blue-and-white plus sign or a red "X" in the icon, double-click it. An inspection window will open. Click the disclosure triangle labeled Trust to disclose the trust settings for the certificate. From the menu at the top, select
    When using this certificate: Use System Defaults
    Close the inspection window. You'll be prompted for your administrator password to update the settings. Revert all the certificates with non-default trust settings.Never again change any of those settings.
    Step 4
    Select My Certificates from the Category list. From the list of certificates shown, delete any that are marked with a red X as expired or invalid.
    Export all remaining certificates, delete them from the keychain, and reimport. For instructions, select
    Help ▹ Keychain Access Help
    from the menu bar and search for the term "export" in the help window. Export each certificate as an individual file; don't combine them into one big file.
    Step 5
    From the menu bar, select
    Keychain Access ▹ Preferences... ▹ Certificates
    There are three menus in the window. Change the selection in the top two to Best attempt, and in the bottom one to  CRL.
    Step 6
    Triple-click anywhere in the line of text below on this page to select it:
    /var/db/crls
    Copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
    A folder named "crls" should open. Move all the files in that folder to the Trash. You’ll be prompted for your administrator login password.
    Step 7
    Restart the computer, empty the Trash, and test.

  • Mail receives but won't send. Upgrade to Lion hasn't helped

    Mail can send messages but is not receiving any.

    Hi, once you have all the correct outgoing server and incoming server settings check your router.
    I had the same issue and tried many times to change the settings in mail and still couldn't send.
    View the router settings and check the devices, if your Macbook is listed as Unknown xx-xx-xx change its name to a single word e.g Macbook.
    Go back to mail if it still doesn't work remove the account and add back.
    This worked first time for me

  • Entourage Receives But Won't Send Emails

    My Entourage had been working perfect for about a year until 2 weeks ago when it stopped sending emails. I can receive emails but when I attempt to send them the following message comes up:
    "An operation on the server timed out. The server may be down, overloaded, or there may be too myuch net traffic. "
    If that happened once I'd be understand, but I havent been able to send mail now for 2 weeks so I know its not the server. Can anyone help?

    Hi Joel.
    Couple of things.
    1) Have you talked to your mail provider to make sure that you have your settings correct, still? Or have you triple checked your settings?
    2) Any changes to firewall settings?
    3) Did you add/change any other software on the day that mail stopped sending?
    (Quit Entourage for the next steps)
    4) Repair Permissions?
    5) Do keychainAccess firstaid, or remove the password in Keychain for this server. Then restart the Mac. Then restart Entourage
    Someone else might have some ideas

  • My mail will only receive but will not send

    my mail will not send i get a message saying it can't send the message using server stmp......
    i can receive mail though
    HELP?

    Ok, several servers seem to have grown more restrictive about the From-addresses they accept and about demanding passwords. There are no open servers anymore that you can use when your own doesn't work. I'm currently busy adding passwords to the servers I'm using after reading advice on these pages. I'm somewhat annoyed that no server ever told me that they wanted passwords, only sending back blunt rejection messages. But my domain server seems to work now at least, hope it lasts. It's only the last week that the server has stopped working completely, and the web hotel never sent me any message that they had started demanding a password for the outgoing server. (The incoming server of course always demanded a password.)
    Another big source of annoyment is Gmail, whose outgoing server always works without asking passwords, but it automatically changes the From-address to my gmail-address. It caused me a lot of embarrassing trouble communicating with my clients recently before I discovered it through finding all their missing answers in the Gmail-folder...

  • Entourage receives but won't send

    my entourage suddenly no longer manages to connect to my service provider's smtp server. it's still connecting to the pop server and receiving e-mails. but when i try to send it just times out. none of the account settings have changed.
    this seems to have coincided with a software update i downloaded for time capsule.
    any ideas on how i might fix this?
    thanks

    Welcome to the discussions!
    I've experienced this was well with Entourage. Powering down the entire system for a few minutes, then starting the modem first and letting it run for 4-5 minutes, then the router for a few minutes and finally the computers has corrected this issue. It's worth a try.
    If you continue to experience problems, contact your ISP to have them test the connection.

  • Server receives, but won't send

    Hi,
    I have setup my 10.4.11 server to send email through mail relay 172.17.3.247, but logging at the logs it is trying to send email to the clients directly. I have put the ip address in, relay outgoing email through host in the gui, but it seems to be ignoring that setting.
    Anyone know why this doesn't work?
    Best wishes
    Michael

    Hi Alex,
    I finally got it sorted out. The relay section at the bottom of main.cf was blank. When I did a search in the file I found a section for relay, but it wasn't that part that needed the relay server. It was the part at the bottom.
    Thanks for your help. It was indeed that command that helped me find it.
    Best wishes
    Michael

  • My new iphone 4 receives mail but won't send it

    my new iphone 4 receves mail but won't send it..

    Depending on what account your using, you may need to enter a password for your outgoing mail server, same password as your incoming mail server - go back into the mail account and check.
