Mail won't send in Leopard-Mail

Hello, I know this subject has been up for a while, but can someone help me step by step to get my mail to send in Leopard? It's a POP account, and never worked in Mail Tiger, but I got it working in Entourage. Now in Leopard, Entourage won't send either. My sending options in Mail always end up in "(account name) - Offline". How can I get that active?
I tried port 110, port 587, but maybe I have confusion in SMTP yes or no, port number,authentication yes or no ...
Thanks for any help!

Dear M.Bode, thanks so much for you advice. It didn't work in Mail, but it did work in Entourage!
In outgoing I did not check the boxes for SSL, I wrote port 25, and no authentication (password).
It sent my test mail. I did the same thing on Mac Mail, and it wouldn't work. Too bad, I'd like to use Mail, and hope the problem will be addressed and the usage made simple again. Thanks again!

Mail won't send attached e-mail.

Greetings,
I'm a new Mac user, and I'm having this problem with my mail account. When I try to send an e-mail that has attachments to it, it takes a long time to send (that is, if it sends). The little blue bar that says "Outgoing messages" is completely full, and it does not send. And it doesn't matter the size of the e-mail nor the size of the attachment, it still does not send.
Please help.
Att.

I don't use Hotmail (I'm allergic to any Microsoft product ), but I'd check both your ISP's and Hotmail's maximum allowed email/attachments file size. I have a Yahoo account and they do have not only a maximum on the number of attachments, but also the file size. Are you sending it to a large number of recipients? That could be another problem - some ISP's limit the number of recipients to discourage spammers.

TS3276 Mac Mail won't send emails with signatures

My Mac Mail won't send emails with signatures. I get the "whoosh" sound and they show in sent mail, but the recipient doesn't receive them until I take off the signature and resend the email. Without a signature, it is received. It never used to be a problem, but started this past month. Please advise!

Did Earthlink have you try using their authenticated SMTP server?
If not, try changing Earthlink's SMTP server settings to the following:
SMTP Server: smtpauth.earthlink.net
Server Port: 25 or 587. Assuming Earthlink is your ISP, 25 should work.
Use Secure Sockets Layer (SSL): Off or not selected.
Authentication Type: MD5 Challenge-Response. Not sure if this authentication type is available with 10.2 and if not, select Password.
User Name: Your entire Earthlink email address.
Password: The password for your Earthlink email account - the same password used to check the incoming mail server for new messages.

Mac Mail won't send .mac mail

All of a sudden Mac Mail won't send mail from my .mac account through it's mail server even though the MobileMe sends mail just fine.
Anyone know what may be up?
I hate using the mobile me mail.

I experienced the same problem--unable to SEND mail using MobileMe server. Changed to port 587, now seems to work (cross fingers).
I also noticed that I cannot change the incoming mail server name from "mail.mac.com" to "mail.me.com." When I try to change then save, it reverts to "mail.mac.com."
By the way, under the "Advanced" menu, can anyone explain "IMAP Path Prefix"? It's blank by default, I gather. Why might someone use a prefix here? Also the default port is 143 and the "Use SSL" block is unchecked.
Merely curious.

See if this helps. I recieved this from Comcast back in November 2012, but may have something to do with it.

Apple Mail won't send invitations when initially closed

I just started using iCal to send invitations for appointments through Apple Mail. When Apple Mail is opened already when I create the appointment and click Send in iCal, it works fine. The mail is sent and delivered to the appropriate address.
But if Apple Mail is closed initially, the application starts and the invitation is queued up in the Outbox but is never sent. I can manually open up each invitation in Mail and send them individually, but why is the behavior different? Whether Mail is opened or closed when I send an invitation, it ought to deliver the invitation automatically. By not being sent, I may not realize the invitation hasn't been delivered, making the process very error-prone. Is there a way to guarantee the invitation actually gets sent without having to check the Outbox every time?
Is this an iCal bug or an Apple Mail bug? I saw no settings in Apple Mail for sending messages at shutdown or any other setting like this. Instead, these invitations may end up being buried in my Outbox for a very long time before I notice and by then, it may be too late.

Since I bought a new modem/router (Netgear n600), my Apple mail won't send e-mails. It will receive. My ISP is AT&T & the email accounts are via yahoo. I have a Macbook Pro with a recent OSX.
The most recent OS is currently OS 10.8.3. Your system profile confirms you are still using Mac OS X (10.7.5). If this is incorrect, please correct your profile so that you will get the correct troubleshooting suggestions/solutions.
Also, post in the OS/Mail forum of whichever OS is currently installed on your MBP. It's where the OS/Mail expert helpers hang out at.

Mail won't send mail when in wireless mode but works fine when wired

Ok, this happens all the time. I have several pop email accounts, all of which work fine when I am hooked in to an ethernet cable, but Apple Mail won't send any of my outgoing mail form any of my accounts when i'm am working wirelessly.
I always get a message like:
Cannot send message using server smtp.name.net
I try to switch servers and I cycle through all of them, getting them same message, followed by things like:
The server response was: 5.1.2 Bad or missing RCPT domain k39sm5757680wah
Any advice.

Go to Apple Menu > System Preferences > Network, choose Network Port Configurations from the Show popup menu, and make sure that the configuration used to connect to Internet appears at the top of the list. Leave checked (enabled) only the port configuration needed to connect to Internet and Built-in Ethernet (in that order if not the same), uncheck (disable) the rest of network port configurations and see whether that helps — if it doesn’t, turn ON again the ones you want enabled.
You may use “network locations” to more easily switch between network settings if necessary, as described here:

Hello Bill,
Who is your eMail provider, the part after the @ sign?
In Mail's Window Menu, choose Connection Doctor, any red dots for status, if so what is the message?
Then click the Show Details button & Check again.

Mail won't send without Connection Doctor having to be launched.

Mail won't send without Connection Doctor having to be launched. After running Connection Doctor, it will send, so settings all must be ok. But 15 minutes later, I need to "check again" to send mail. I read previous posts on this from a few years ago, but my laptop is running Lion.

Try just watching the "Activity" window to learn what is happening to your mail - I have found it to be most enlightening.

Mail won't send but Connection Doctor says smtp account OK.

Mail won't send but Connection Doctor says smtp account OK.
I can receive mail but can't send it from Mail 3.5. Same problem on a wired G5 and on a wi-fi MacBook (using the same account), so not hardware related. Worked fine 'till today - I didn't change anything in between times. Incoming mail no problem. Tried mail rebuild, keychain first aid, deleting the account, repair disk permission - doesn't help.
Mail's connection doctor says "smpt.xxxxxx - connection to server succeeded, no login required."
Anybody any ideas? Thanks, N

Been having the same problem for a few weeks now. This has been working just fine, and all of a sudden - nothing. The update to 10.5.6 didn't do anything to fix this either.
I've spent numerous hours on the phone with the Apple support. Seeing as the two other accounts that I have configured work with no problem, they say that this is a problem with the provider which is also the ISP. I then called the support line for the ISP and informed them of this and they say that it's a problem with the software.
Interestingly, if I send a message to somone with the same ISP, the message will go. But I can't send a message outside of the provider. Does anyone else have this problem?
Also, from another forum, they suggested rebuilding the LaunchServices database. The Apple support didn't see what that would do. But I tried it anyway and the problem still exists.
Another intesting thing is certificates. It's only happened twice, but I've received the message saying that Mail can't verify the certificate XXXXX which validates the identity of the smtp. Anyone else get this? I thought perhaps I could delete the certificate and it would magically reappear. But when I go into KeyChain, the certificate is listed only under System Root and I can't delete it.
ideas?
