Mackbook pro receives packets but won't send

hi. I'm trying to migrate some data from my old Mackbook pro to my new imac using Migration Assistant, or from Finder/Shared.
I am having problems. Using Network Utility i discovered that the imac is sending and receiving packets, but the Mackbook is ONLY receiving , NOT sending. Any ideas?

resolved.

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.

IPhone 5 receives emails but won't send them

-- now sorted thanks to Judian35's reply (Jan '13) to a previous query. Worked a treat, but the email sending should've worked first time surely? Seemed a strange sort of fix to me. Diesels and hydraulics more my bag....

You will need to go to your email settings - SMTP outgoing mail server and make sure the password is correct.

Mail receives emails but won't send

I receive emails from my hotmail account, but I am unable to send. Have tried deleting account and reentering it. Have deleted my outbox and the circle is still spinning around next the the 'sent'. This is annoying Apple - sort it out!!!

Hi emibarwell
I am in the UK and eventually found the problem was due to my BT Home Hub Router.
I found this fix below on https://discussions.apple.com/thread/4604180?start=15&tstart=0
It worked for me. If you can't link to the URL, here is the body of the text
There's an issue related to the BT homehub that is providing a hostname that is "syntactically incorrect" for several smtp server.
Here's how you can fix it.
Using your internet browser, go to the address "192.168.1.254
- Follow instructions to reset your password if asked.
- Then go to "Settings", then "Advanced Settings" and "home network"
You will see there all the devices that are connected or that has been connected before. It's gonna be easyer if yout computer is the only one connected.
Your computer should have a name like "unknown-xx:xx:xx:xx:xx ...
Click on this name, chose another name without any special characters, like "macbook" for exemple.
And then click on "apply"
- restart your computer.
That should fix the issue.
Credit goes to vincentfromcork for providing me with the solution.

Palm TX receives email but won't send message

My Palm TX works great receiving messages with both my work and personal email through VersaMail.
It acts like it is letting me respond to the messages, but they are never received.
Can anyone tell me what's going on, and how to fix it?
Thanks. Hank
Post relates to: Palm TX

the reason for that is, your outgoing mail server that you have is block by your internet provider.
try using an alternate outgoing mail server like the outgoing mail server of gmail.
Outgoing Server Settings:
smtp.gmail.com
Port Number: 587
Use Secure Connection (SSL): No
Use authentication (ESMTP): Yes. Requires username for ESMTP.

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
enzo

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.

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).

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts Tap on the Account, then on the red button that says Remove Account.

Email handler receives email but won't transmit emails:VIDCHAT/ICHAT OPTION

Email handler receives email but won't transmit emails:VIDCHAT/ICHAT OPTION is non-functional...
After three decades of Windows I decided to find my spouse a birthday/Christmas IMAC but if I don't do something soon about this learning curve we may part company after 44 years...
Is there someone out there that can assist me with these issues?
:>/

Okay, now that I'm in the right forum I see that this seems to be an ongoing problem. I checked the antivirus and that didn't do anything.
I did change the port from 25 to 587 and that seems to have opened up the outgoing emails. They've seemed to been sent since they're no longer in the outbox.
BUT...now I can't seem to receive emails. Ugh......
I ran the Verizon email fix app and it says it couldn't send an email now and I should call the 800 #. What the heck is going on here when everything was working perfectly before?!

I can receive emails, but I cannot send emails. This just started happening. I have an iPhone and I can send emails from my phone fine. It's just not working on my Macbook. Every time I try to send an email it goes straight to my outbox. Can anyone help?

Thank you for heading me in the right direction. I reset my Mail account for Outgoing Mail Server to outbound.att.net:(customer ID)@att.net (instead of smtp.att.yahoo.com, per Apple's online troubleshooting information). I'm not sure what "(Offline)" means when it appears at the end of my Outgoing Mail Server (SMTP)?? In the Advanced box I clicked on "Use custom port: 465" and checked "Use Secure Sockets Layer." Authentication: Password; I have correct User Name and Password put in. After doing all this, when I try to send emails again today, they go directly to the Outbox and sit there.
What's curious is that my first sent email this morning did go out using the Outgoing Mail Server, smtp.att.yahoo.com: (customer ID)@att.net(Offline) but subsequent emails I tried to send with this server were rejected with the message: "Cannot send message using the server smtp.att.yahoo.com (etc.). The SMTP server doesn't support TLS(SSL) on port 587. Verify your account settings and try again." That's when I tried resetting my Outgoing Mail Server to outbound.att.net (etc.), as mentioned above, and was unsuccessful in sending out any further emails. I guess my next step is to contact my email service provider, AT&T, and see if they can help me. Thanks, again, for taking the time to respond and for giving me your input! Much appreciated!

Problem: Cannot send mail unless Password is transmitted insecurely & Port is set to 587.. Can receive mail but can't send..

Problem: Cannot send mail unless Password is transmitted insecurely & Port is set to 587.. Can receive mail but can't send Code 501..
Need help with T-bird.. My OS is Win XP-64..Have been using Mozilla for about 10 years with little or no problems.. This happened when I upgraded to 3.17.. Spent hours on T-Bird diagnostics web site.. Called Comcast & talked to a net tech.. he ran some tests on his end & had me log into my Comcast e-mail account & all worked well,, so he concluded the problem was in T-Bird.. He had me change my port to 587 & disable connection security & authentication to none & I was able to send mail.. That was all he could do.. Comcast was working.. the problem is in T-Bird.. Can any one help with this problem.. I don't want to send mail with my password transmitted insecurely..
Thanks
Richard

It was not intended to be "snide". You said two separate things that at face value would be out of the ordinary.
I considered if it might be a typo for 31.7. Since 31.5 is the current formal release, I would have to thank you for volunteering to test a pre-release beta version. If it was truly 3.1.7 then it would appear that you have chosen, or have become stuck with a somewhat ancient version. In either case it's harder to reach out to you with any meaningful comments or advice. However I do watch various other sites and newsgroups and I don't see a clamour of distressed users, so it seems fair to suppose that this feature isn't actually broken in 31.7.
And you said XP 64. XP is obsolete and no longer supported and if there is a 64-bit version, then again you have set yourself apart from the mainstream.
I had a look at the comcast site and found some puzzling recommendations. Some users come here asking how to set up a secured connection in Thunderbird when it isn't offered by the server. Comcast are different, in that they mention the ports 143 and 587, and also 993 and 465. So far so good, in that security is actually on offer, but they also suggest that you enable SSL, regardless of which port is being used. It would be unusual and unconventional to offer TLS or SSL on ports 143 and 587. STARTTLS would be more credible on these ports.
Have you tried IMAP on 993 and SMTP on 465? SMTP on 587 with SSL, or TLS, is not impossible, but is improbable.

Exchange Server 2007 OWA users can receive email but can't send

Hi,
I have an Exchange server 2007 in an SBS 2008 environment with POP3 connector configured and working fine , smtp send mail connector configured.
Now users can connect to OWA, receive email but cant not send.
smtp connector works fine from Outlook client. Tried to track the emails from exchange server management console and I get the
SEND DELIVER SUBMIT TRANSFER.
The emails go to the sent items folder, but it never reach the recipients.
Have been troubleshooting for a while without succes. Any help will be most appreciated.
Regards
Faisal

POP3 is a single mailbox client mail retrieval protocol, not a mail transport protocol.
Any attempt to use it as a mail transport protocol is a great big kludge.
Exchange is designed to connect to the Internet using SMTP.
No version of Exchange has a POP3 connector.
I recommend that you post this in the SBS Forum: http://social.technet.microsoft.com/Forums/en/smallbusinessserver/threads

Mail receives OK but will not send for smtp account. Exchange server receives/sends OK

mail receives OK but will not send for smtp account. Exchange server receives/sends OK I'm away from home, using a family-member's wireless network that has always worked OK in the past. Today, the same problem occured while waiting in a hospital waiting lounge. Any ideas?

The outgoing mail server may be rejecting mail from your network address. Typically that happens when your mail service provider is also your ISP, and you connect to it from another network. The SMTP server will allow connections without a password from anywhere, but it will only relay mail from within the ISP's network. It could also be that your account on the server has expired or been suspended.
If you need to send mail from outside your ISP's network, use an independent mail service provider. I don't have a specific recommendation.
