Who is the email account provider for this email account and outgoing mail server? Is it your internet service provider or other?

Are you using the Mail application and have you ever been able to send messages with this account?

You can receive messages with your .Mac account but not send?

Are you also accessing an email account and SMTP server that is provided by your internet service provider with the Mail.app and if so, are you able to send messages with this account?

Who is your internet service provider?

Alan, I am able to receive messages. I have another email account through road runner and went there and sent an email to my .mac email address.

I'm not sure on your other questions. ISP is through a shared office.

This problem started right after I tried to send an email to a group of my clients etc.

Thanks

This problem started right after I tried to send an email
to a group of my clients etc.

Was this group email successfully sent by your .Mac account?

How many recipients were included with this group mailing?

Do you send a number of messages to a large number of recipients on a daily basis with your .Mac account?

As with most other email accounts, .Mac has a sending limit on the total number of recipients per message and the total number of recipients for all messages sent in a 24 hour period.

You ISP at home is RoadRunner but you use a different ISP at the shared office?

If you are also accessing your RR email account with the Mail.app and RR is not your ISP at the shared office, are you able to send messages with your RR email account and SMTP server when connected to the internet at the shared office?

Just hitting all angles in an attempt to eliminate possible causes of this problem.

Was this group email successfully sent by your .Mac
account?

No; that was the first time I received the error message.

How many recipients were included with this group
mailing?

30+

Do you send a number of messages to a large number of
recipients on a daily basis with your .Mac account?

No; I do periodically, maybe 3-4 times a year to announce major changes with firm. Emails have worked in the past but possible I did them from my road runner account.

As with most other email accounts, .Mac has a sending
limit on the total number of recipients per message
and the total number of recipients for all messages
sent in a 24 hour period.

You ISP at home is RoadRunner but you use a different
ISP at the shared office?

Yes; trying to find out who it is.

If you are also accessing your RR email account with
the Mail.app and RR is not your ISP at the shared
office, are you able to send messages with your RR
email account and SMTP server when connected to the
internet at the shared office?

I access the RR email via the RR website, not via the Mail App.

Just hitting all angles in an attempt to eliminate
possible causes of this problem.

Based on your response, you don't use the Mail.app often to send messages with your .Mac account when connected to the internet at the shared office and you aren't sure if you have successfully sent messages with your .Mac account using the Mail.app when at the office.

Go to Mail > Preferences > Accounts and under the Account Information tab for your .Mac account preferences at the SMTP server selection, select the Server Settings button below for the .Mac SMTP server.

The settings should be as follows:

Outgoing Mail Server: smtp.mac.com

Server Port: If 25 is entered, enter 587 in place of 25.

Use Secure Sockets Layer (SSL): Can be selected or not selected. I have it selected.

Authentication: Password.

User Name: The portion of your .Mac email address in front of the @ sign only.

Password: The password for the account - the same password used to check the incoming mail server for new messages.

If any changes are made, select OK to save the changed setting.

Based on your response, you don't use the Mail.app
often to send messages with your .Mac account when
connected to the internet at the shared office and
you aren't sure if you have successfully sent
messages with your .Mac account using the Mail.app
when at the office.

I DO USE THE MAIL APP OFTEN AT WORK AND HAVE SUCESSFULLY SENT MESSAGES IN THE PAST.

Go to Mail > Preferences > Accounts and under the
Account Information tab for your .Mac account
preferences at the SMTP server selection, select the
Server Settings button below for the .Mac SMTP
server.

The settings should be as follows:

Outgoing Mail Server: smtp.mac.com

Server Port: If 25 is entered, enter 587 in place of
25.

Use Secure Sockets Layer (SSL): Can be selected or
not selected. I have it selected.

Authentication: Password.

User Name: The portion of your .Mac email address in
front of the @ sign only.

Password: The password for the account - the same
password used to check the incoming mail server for
new messages.

If any changes are made, select OK to save the
changed setting.

I TRIED THIS; ONLY THING THAT WAS DIFFERENT WAS MINE WAS ON 25; I CHANGED IT TO 587 BUT NO LUCK, STILL NOT WORKING.

I appreciate your efforst thus far. It's a mystery.

The error box I get states "The sender address ....was rejected by the server".

Sorry that I misread your reply to my previous question regarding using your .Mac account and SMTP server with the Mail.app to send messages when at the office which IS NO REASON TO SHOUT AT ME.

As a test, it would be good to create your RR email account and SMTP server with the Mail.app and test if you can send messages with your RR account when connected to the internet at the office.

If the ISP you are using at the shared office is not RR and they made a recent change in regards to using SMTP servers that are outside of their network, you shouldn't be able to send messages with your RR account and SMTP server either.

As another test, try selecting None for the .Mac SMTP server authentication.

I will try that; please accept my apology. I was not intending to shout. I used caps to differentiate your text with mine. I should have used bold or italics or something like that. I wasn't shouting. I forgot that some people consider caps as shouting. You are the only one that has been trying to help me. If you were a mac employee, I might be shouting right now. 🙂 LOL

I will try your other suggestions.

That's OK and apology accepted. 🙂

I know problems like this can be time consuming and frustrating but if you don't mind, I'd like to offer you some advice for future reference here.

The Apple Discussions contains a wealth of knowledge that comes from some very knowledgeable folks that choose to participate here. I learn some new things here on a regular basis but if you post here again with a problem or question, be sure to include as much relevant information as possible in your original post which avoids a number of additional question and answer posts in an effort to determine the cause of the problem and provide a resolution.

One more thing, if you create your RR email account and SMTP server with the Mail.app and are able to send a message with the account when at the office, you should be able to select/use RR's SMTP server to send messages with your .Mac account in the interim while determining the cause of the problem.

RR is my ISP also and I use RR's SMTP server to send messages with my .Mac account when connected to the internet at home.

Thanks; will keep that in mind if I return here. I'll try using the RR account here to see if that works. Not sure why Mac doesn't have a number you can call for .mac issues; that is frustrating.
