Unable to send mail, but only at my office (!)

This one is really strange. Lots of information gathered over the last 10 days or so, on which I can't send mail through two of my accounts.
I got this new MacBook Pro with Snow Leopard factory-installed. This is not an upgrade problem.
I imported my user account from a Time Machine backup, but did not import any apps or system files. I had to install all my 3rd party apps, configure networking for my two locations (Home and Office), etc.
The problems started on 10.6.0. Mail couldn't send messages through any of my accounts. Receiving has always been OK. Updated to 10.6.1 and problems went away.
Since the 10.6.2 update, I can't send mail again, but in very special circumstances:
- Only two of my mail accounts, hosted at my hosting provider, have this problem. Gmail works flawlessly, though I feel a little lag before actual mail is sent, specially at my office;
- Only when I am at my office, where we use public IP addresses on the LAN. Everything works perfectly at home or other places (public hotspots, other networks, etc.) where private IP addresses are used on the LAN!
All other Macs at the office, which use Leopard (10.5), work fine and dandy. We don't use DHCP. All computers are configured manually and connect to the same wireless network. I already checked my firewall and both the ISP and hosting provider.
I already did everything mentioned in other threads here: repair permissions, rebuild mailboxes, everything! I even created another user account on my Mac and configured everything from scratch. I didn't re-install Mac OS X, though.
Any ideas?

Barry,
I did that. I also tried deleting that plist and reconfiguring all my mail accounts, but that didn't work.
Then I thought I could get the problem solved by creating a new user account on my Mac -- a clean home folder should eliminate the culprit --, but it didn't work either.
I decided to give up on that, now that I can send mail anyway. I will let this question as unanswered so people can suggest possible fixes.
Thanks for caring and trying to help!
One more piece of info that can help:
- Connection Doctor showed me a red bubble for these accounts, telling me to check the username and password.
- Looking at the details (log drawer of Connection Doctor), I saw that my mail server was responding with a 250 code, but Mail waited 30 seconds to send the EHLO command. By that time, the server had timed out.
- Mail would then try again, but this time it would send a HELO command, which my mail server does not accept.

  • Can't send mail; but only some times

    Since I updated my computers to Tiger I have the same problem on all of them.
    Mail doesn't send mail, I have to quit and try again and again until it does. Read all articles about similar problems but non of them helped. As far I understand there is something going on with the port 25, but then, why some times it works some times doesn't?
    Maybe I just switch to Thunderbird, but that's also a pain because Mail doesn't let one simply import to another mail program.

    What does “Mail doesn't send mail” mean? What’s the problem exactly? What error messages do you get, if any? Are this mail account and the associated outgoing (SMTP) server provided by your ISP or by someone else? More info, please.

  • Unable to send emails but only retrieve from friends wifi.

    Staying with friends for the month and can only retrieve emails but not send. Help!

    If you are using your ISPs email settings you should check with them for the SMTP settings needed when connected to a remote network (your friend's ISP). Nost ISPs require authentication or different SMTP ports to send when you are not connected to their network.

  • Mail uses wrong identity when sending mail but only in a very specific case

    Hey there we have a very strange thing happening here. There are two accounts in apple mail. user 1 is set as the default account and when user 1 replies to email sent to him it works as it should. When email is sent to user 2 and he replies it works correctly as well. But when an email comes addressed to both user 1 and user 2 and user 1 replies it is being sent as user 2 not user 1. Any ideas on what is causing this?
    Thanks for your help

    When both addresses in the To header are setup in Mail, Mail defaults to choose the first address listed in the distribution. You have to manually change that, or have separate User Accounts on this Mac for each user, and in that case each user would only setup his/her account.

  • HT1277 i can receive mail but unable to send mail

    i can receive mail but unable to send mail

    I'm yet another person who upgraded to Maverick OSX. I'm now thinking, "BIG mistake". Mail was working perfectly. Then, last night, Mail stopped sending.
    I've checked everything. Comcast servers are set up correctly. Mail works fine on my ipad, but will not send. It gives me a SMPT error of "Cannot send message using the server comcast.net--authentication rejected" Comcast.net (Offline). I can not get it back online. I've also tried the fixes here, but there is no info.plist by those names in my library!
    Anyone have any other ideas how to get this working again? Apple's OS's have been pretty decently stable in the past. I had no thought that the upgrade would be so problematic. Live and Learn.
    Thanks for any suggestions.

    Your outgoing server settings are probably incorrect. Check them.

  • Unable to send Mail from POP account

    I have an Iphone 4 and have upgraded the IOS from 5-1 to 6.1.3. Since then I have been receiving all my mails but i have been unable to send mails from my POP account. the notification "Cannot Send Mail. A copy has been placed in your Outbox. The receipient, "xxyyzz @ gmail . com " was rejected by the server" displayed. Please Help. the same thing happens when I configure my POP account on my Son's Iphone4, and there is no problem in receiving and sending mails from my Outlook. Please Help!!!!!
    Can i revert back to IOS5.1.1?????

    Contact your email provider and get the correct settings to use for the outgoing mail server (SMTP) on a mobile device. If it's email provided by your ISP, they have likely blocked email from outside their network from relaying to prevent spam.

  • Unable to SEND mail using Activesync in Exchange 2010 server on iPhone or Windows Mobile 6.1

    Hi All,
    We've been setting up a new SBS 2011 server for a client this week. Everything is working, except the staff have 4 x iPhones to connect with Exchange ActiveSync.
    There are 2 x iPhone 4's and 2 x iPhone 3Gs's. We can setup the Exchange accounts on each of the phones and they are all able to sync mail and calender etc with the server.
    The problem we have is when any of them try to send mail from the phone, it gives an error : "Cannot Send Mail - An error occurred while delivering this message" and it sits in the outbox on the phone.
    The newsgroups and forums are littered with people having issues with IOS4 and Exchange 2010 but most of these are from June-August 2010 when IOS4 version was around 4.00 or 4.01
    A lot of these people had iPhone 3 handsets running with IOS 3.1.3 which worked with Exchange 2010 but when they upgraded to IOS 4, they had this problem sending mail.
    It seems that for most of them, the fix came in the form of IOS version 4.1 which fixed the send issue for them.
    We have a variety of Hansets and IOS versions (including an iPhone 3Gs running IOS 3.1.3) but are unable to send mail from any of them:
    iPhone 3Gs    IOS 3.1.3
    iPhone 3Gs    IOS 4.3.3
    iPhone 4       IOS 4.3.3
    iPhone 4       IOS 4.3.5
    I was surprised that the iPhone 3Gs running 3.1.3 was unable to send either as nearly all the forums etc I read with this issue said the iPhone 3's worked with that IOS version.
    Today we used a test iPhone 4 handset from our office to connect to an almost identical Small Business Server 2011 we setup two weeks ago for another client.
    The test iPhone 4 was able to connect, Sync and Send email on that server but when set it to connect to this SBS 2011 server, it gets the "Cannot Send Mail" message the same as the others. So clearly the handset is working (on the other server at least),
    it must be something misconfigured in this Exchange server right?
    We ran the Exchange Remote Connectivity Analyser on the Exchange server and got green ticks across the board.
    Outlook Web App and Outlook Anywhere both work normally. Everything we can test on the Exchange server works except sending from any iPhone.
    Having said all that, I just setup a Windows Mobile 6.1 handset to sync with the Exchange 2010 server as a test, and it appears to have the same issue.
    It will connect & Sync Mail, Contacts and Calendar but if trying to send an email from the phone, it will just sit in the outbox.
    Does anyone have some insight into what the problem may be?

    Further to this .. I found the solution on a MS Exchange 2010 support forum.
    It was not a certificate or firewall issue, looks as thought the “Accepted Domains” in Exchange Mgmt Console –
    Org Config – Hub Transport cannot have any spaces in the name field.
    I had some spaces and the emails were not downloading fully and able to send. Once I removed the spaces from the Name field and
    restarting the Exchange and IIS services emails were now being sent and received ok.

    Here is what I did to resolve the problem:
    In Mail/preferences/accounts/account information/ and at the bottom of the box there is a toggle arrow up and down to edit the outgoing mail server, check the box "use only this server" and  hit this toggle button and select "edit SMTP Server List" at the very bottom of the email names.
    Select Advanced tab.  Correct and/or add usernames and passwords as needed for each email account.  Be sure to select OK each time to get the passwords to hold!  Some changes don't seem to hold unless you click OK before you move on.
    To test:       Window/activity (a little windows will pop up showing activity bars)   and then "get mail" button.  This should show any problems
    Another test:  window/connection doctor
    This shouldl fix both pop and imap.  so far it worked on yahoo, mobile me, gmail, hotmail, and others.  Of course, you will need to know the incoming and outgoing mail server info, user name, and passwords.
    Too bad we have to go though hoops to use an email program that used to work well.  Worse yet, many may not know for days that their email isn't working.
    This is easy method of setting up your email accounts but may not allow enough detail to make the mail accounts function properly in Mail 5.0:
    system preferences/internet and wireless/mail, contacts, calendars/ add account

    Hello,
    Actually i checked the mail ID for WF-BATCH  using su01 .But i didnt find any mail ID for WF-BATCH then i added the email address of the user.Then we tried sending mail it was successfull.
    But later i removed the email address what i entered in WF-BATCH user .Even after removing the email address also iam able to send the mails through workflow.

  • "Unable to send mail" using Verizon email account

    No matter what I try, my Incredible will not send an email using my Verizon email account. I receive emails but cannot send. I've verified the account settings numerous times and the verifications always work. But I still get the "Unable to send mail" message. Initially I thought it was the port but I've tried both 25 and 587. Neither work. I know I've sent messages before but it's been a while. Anyone have any ideas?

    I tried SSL with 25 and 587 (Verizon recommendation). Still no go.
    BTW, there isn't any way to save the Mail size limit and Download options is there. Every time I go thru this I have to go back and set these up again.
    Thanks again for your help.

  • Unable to send mails from Azure SharePoint 2010 VM

    Hello All,

    But i am able to send mails from my on premise VMs to external domains.

    Hey There,
    Azure does not support smtp relay, you may want to use SendGrid (which working with Microsoft Azure).
    After registration you get 400 E-mail per day free of charge.
    From technical aspects youll get SMTP server, Username & Password which you can fill in your application.
    Hope it helps.

  • Can't send mail but connection doctor says server is ok

    I changed my MS Exchange username from [email protected] to [email protected] but my email address remains [email protected] So I changed my account settings (I have the exchange account set up as IMAP. I can receive messages but I cannot send. I have checked the settings a thousand times, they are correct. The funny thing is the connection doctor says my outgoing mail server connection is good "Connection and login to server succeeded", but when I try to send send a mail I get "Unable to send mail, check x y z" I don't remember the error exactly because now the send button is just grayed out when I try to send from that account.

    I installed Eudora and imported my mail settings from Apple Mail. I did NO entry of the server settings, it came directly from Apple Mail. I can send from Eudora but I cannot send from Apple Mail. Go figure.

  • Mail app won't send mail, but it will receive mail

    The mail app on my macbook pro and iphone will not send mail, but they can recieve mail.  I deleted both accounts and reloaded them and they still won't work.  After that I ran repair permissions and it found nothing wrong.  Has anyone experienced this problem and how can I fix this?

    I had same problem with my MBA and Mac Desktop (don't have iPhone)...could receive but not send emails after Lion upgrade.  I only experienced it at home versus at work (inconsistently on both on my macbook air and my desktop mac).
    For me the solution was when you compose an email there are two dropdown listboxes next to From:  ...in the second one select smtp.me.com:yourusername   Until Apple makes a change you might need to do that each time you send or reply to a message.
    I think it has something to do with if you don't do that then port 25 might get used which can be blocked by a lot of ISPs.
    Apple support helped me solve this problem and said it was a known issue they are working on.
    Hope this helps with your issue!
