hi
i keep receiving 2 messages straight after receipt of the original which is readable..
1st message: mail delivery fail
2nd message: undeliverable
i have no problem reading the original message

This is a problem with your recipients ISP not delivering the email, or with Comcast in not sending it once it reaches their mail servers. You should check with your recipients to find out if they use the same ISP, and have them check with the ISP to ask why mail sent from a Comcast account is not being delivered.
If this affects all your recipients (assuming there are many more than just the two you mentioned), then its a Comcast issue and you should call them and insist they make any necessary changes so everyone can receive email from you. If it only affects those two recipients, they would need to call their ISP and have them make the necessary changes.

  • I can no longer send e-mail in TB but still receive it.

    Recently TB quit allowing me to send e-mail messages. I still receive mail, but when I try to send messages, I am prompted for a password. It does not accept the correct password. I can send messages from my iphone and a web-based e-mail app, so it is not a problem within the account, just with TB. How to I correct this problem?

    Get a list of SMTP server settings from your email provider and check those against what you have in Thunderbird. Maybe one of the SMTP server settings needs updating.
    If you need help looking at your server settings, go to the Help Menu and select Troubleshooting Information. Clear the box to include Account Names. Press the button labeled Copy All to Clipboard and then come back here and paste that info to a reply box.

  • Cannot send mails via IMAP but can receive mails

    HI All
    Having Exchange 2010 SP2 on standalone box on W2K8R2-std sp1
    We enabled IMAP and POP3 for our user base who do not have Outlook or are facing issues with active sync. 
    mailbox gets configured however none of mails are sent via IMAP  they remain stuck in user outbox only.
    They can receive mails but can't send. we tried configuring same users on Outlook and activesync and it worked. 
    We were surprised with some mis-configuration at IMAP end but could't get to root of it. Any idea what could be an issue????
    for imap testing we tried Zimbra 7.2.3 on windows 7 pro, Windows Mail app in windows 8.1. IMAP in windows phone 8
    Have enabled IMAP and pop3 logging but couldn't interpret it.
    Cheers VP

    Hi vp89,
    Based on my knowledge, POP3 and IMAP cannot be used to send messages.
    E-mail applications that use POP3 and IMAP4 to send messages rely on the SMTP protocol to send messages.
    The connector for receiving e-mail submissions from client applications that use POP3 or IMAP4 is created automatically on every Hub Transport server.
    We need a Send Connector.
    More details in the following articles:

  • Yosemite mac mail drowning in mail delivery failed messages I didn't send!

    babs bellNov 14, 2014 7:03 PM
    Since upgrading to Yosemite, I am getting hundreds (tens of thousands this week!) emails that read:
    From: Mail Delivery System
    Subject: Mail delivery failed: returning message to sender
    But I didn't send any of the emails! I've spent this entire week deleting them, working on phone with my server who claims to have fixed it (NOT!), and 5 hours on phone support with Apple today. Still happening. There must be a setting that is screwed up in Yosemite, eh? Who can help me? Using Mac Mail on Mac Book Pro. I'm drowning here! GLUG. Thanks!
    Edit

    Did all of that with Apple and they nor my server thought this was the problem, nor did they get it resolved. I'm wondering if there's a rule in Mail preferences that I accidentally deleted that could be the cause. There were two rules and neither made any sense to me but as soon as I deleted the first one, I realized I probably shouldn't have. And there's been a huge problem since...not sure that's why but I must find the resolution. I did have genieo somehow installed so Apple got it uninstalled and did tons of things to my system to clean this and that. BUT the problem remains. If you use mac mail and Yosemite, can you check the two rules that automatically were in the mail preferences window to tell me what rule I deleted? Thank you so very much!

  • Mail delivery failer Command rejected 550 5.7.1

    Product: Officejet 6500A
    OS: Windows XP
    First time installation
    All indications show that the printer connected to ePrintCenter, but still I get an mail delivery failer Command rejected 550 5.7.1
    I tried everything that appears on the forum.
    Please help

    same by me ... no EPRINT is working

  • Mail delivery failed

    eprint center shows computr connected email address is allowed to send email to printer but when i send email get mail delivery failed  this is a permanent error 550 5.7.1 command

    For those who are experiencing ongoing issues with their web services, you can attempt to try the following steps that may help resolve your problems.
    1.) Completely shut down your printer and restart it
    2.) If you have prints that have not printed, log into ePrint Center (or create an account if you do not have one) and then look for your printer status. If printer status is green but you still have pending jobs, delete the pending jobs one at a time (Starting with the oldest first). There may be a print job stuck in the queue that further restricts other jobs from completing.
    a. If option 1 or 2 above still doesn’t work, removing web services and re-adding web services will cause the printer to reattach to the cloud.
    b. Please note that if you attempt option 3, you will get a new eprint email address (and lose your custom one with no ability to get it back) furthermore, you will need to re-add your printer back to your ePC account.

  • 1000's of mail delivery...notices received ? pls help

    Hello, since few days, I receive 1000's of failed mail delivery....notices
    mails are sent using new e-mail adresses from my domaine...it's becoming crazy and the guys at our hosting can't seem to fix it.
    thanks for any advise ))

    That means that a spammer somewhere in the world has spoofed your e-mail address as From. There's nothing you can do about it. Just wait it out and they'll move on to someone else's address.

  • Cannot send but can receive mails

    Hello. I have a MacBook with Mac OS X 10.4.11. I use a “.wanadoo.fr” account with an internet access through a Free internet box. So I used a pop.wanadoo and a smtp.free for the mail account. All this worked fine till 10 days ago. Now, I cannot send any mail (via the smtp.free) whereas I still receive mails (through the pop.wanadoo) and I always can surf the internet. For info : a pc which is connected to the same freebox can send mails with the same mail account. Other mistery : I ping successfully any internet address (from my Mac) but not my freebox, 2 feet away !?! And when I ping my Mac from my pc, nothing is found. As if the Mac was out of the local network. Any idea ?

    Check with your ISP, many have changed the outgoing Mail port without telling anybody!

  • "Mail Delivery Failed:returning message to sender" recipients not familiar

    I am getting a "Mail Delivery Failed" message. The address' that failed are to recipients I am not familiar with and have not tried to email. Has my email been hijacked?

    I'm getting the same problem ... only it happens to anyone who sends a message TO me. This only happens on my .mac address --- not other email addresses that I use. It's as if the .mac smtp code is ADDING a bcc to any message sent to me! All the comments to date have been less than encouraging - surely SOMETHING can be done about this! No?

  • Upgraded to Tiger; Mail can Send, but not receive... help!

    Hi there,
    I've come across lots of issues people have had importing all their mailboxes when they've upgraded from Panther to Tiger, but my wife's problem is different - - Mail can Send, but not receive. 'Get Mail' hasn't worked since the upgrade. I've been on the phone with my POP server provider, and all my Mail Account settings are correct. I can send mail, as I say, and sure enough, there it is in her Hotmail web page, along with all the other messages people have sent her in the last two weeks...
    So why can't Mail 'get' these messages, if all the settings are correct?
    Any advice would be appreciated.
    Malcolm

    You’re welcome.
    If you deleted a POP account, then all the messages stored in that account’s mailboxes has certainly been wiped out, not just moved somewhere, and you were warned that this would happen by the following alert:
    Remove Account
    Are you sure you want to remove the <AccountType> account "<AccountName>"?
    This will permanently delete the account setup information, mailboxes, and messages from your computer. Messages stored on the mail server will not be affected.
    To prevent that from happening, you should have moved those messages to custom “On My Mac” mailboxes instead of leaving them in the account’s mailboxes. Actually, using Inbox and Sent for archiving purposes is a bad idea regardless.
    If the messages are not on the server and you don’t have a backup (which you should have made before doing something like that), you may try to salvage as many deleted *.emlx files as possible with a data recovery tool such as Data Rescue II, TechTool Pro, or FileSalvage (the files to be recovered would be different in the case of Mail 1.x). Of these, the only one I know for sure that can currently recover deleted *.emlx files is FileSalvage. Stop using your computer right now if you want to try that, as anything you do with the computer may cause the deleted files to be overwritten.

  • Thunderbird Issue. Thousands of inbound e-mails from "Mail Delivery Failed" from people to whom I've never attempted to send an e-mail.

    All inbound e-mails are going directly to "TRASH" how do I fix this? I also have has thousands of inbound e-mails from "MAIL DELIVERY FAILED" involving people to whom I have never attempted to send an e-mail. Whats the cure? I have to use Time Warner as an internet connection and there is a duplicate of about half of what I'm getting in inbound traffic on Thunderbird.

    The inbound is Backscatter see http://en.wikipedia.org/wiki/Backscatter_%28email%29
    The trash issue is most likely the SPAM tool that comes with your anti virus program. Try disabling the tool in the anti virus suite and see how you get on.

  • Mail 3.6 stuck, wont receive mail

    I am stuck. I open up mail and it begins to receive mail, but then resorts to receiving x out of 1021 emails until it gets to around 35 out of 1021, sometimes more sometimes less, and then the receiving rate gradually goes down to 0kb/s and then just sits there for hours, and maybe ticks over to the next email sometimes.
    I have logged onto the webmail and deleted any large emails around the last email received from the server..
    HELP!

    Hello and welcome to the Discussions.
    Is this a POP or IMAP account?
