New email settings with MS Outlook for Mac Heather657483030 10 months ago I updated the settings as per all the instruction received - yes i've gone to the page where you check off what email client you're using and yes, i've gone to 'Other' but there is no specific guidance on how to change for MS Outlook - for Mac.
Junior Member Yes, it was working prior to November 20, 2007. I had not tried to use Outlook Express except as a test for Outlook. Since both failed I was thinking there must be some common feature that is used to send mail outbound. I don't have any issues receiving. Yes, I have worked thru all the proper setups, I think, for Outlook and it appears to be configured properly. Running Outlook 2003.

This is stated as server not as port. Maybe I'm not looking in the right place. This is under email accounts and more settings. Anyway I think according to COMCAST I have the correct settings. Bill Eyler 'F.

SMTP was checked with COMCAST as 25. This is stated as server not as port. Maybe I'm not looking in the right place. This is under email accounts and more settings. Anyway I think according to COMCAST I have the correct settings. Ok, how about this. That last URL I gave you.
Can you set up Outlook using the steps in that URL and try to send mail?

This is getting a little more interesting. I don't have Outlook open and running yet I'm getting these send error messages anyway.
How can the system be attempting to send messages when I don't have Outlook open? Because either something kept it open, or you have it set to minimize to the systray. If you open up Task Manager, is Outlook.exe listed on the Processes list? Is the Outlook icon in the system tray at the lower right? How did you close Outlook? Junior Member Tried 587 instead of 25. Task manager does not show Outlook open and it's not in the system tray.
The sending I was getting was because I put my PDA on to charge and apparently that causes it to check for or try to send messages. Bill Eyler 'F.

This is not checked and shouldn't be. A radio button 'Log on using.'

I can recieve messages but I can't send them. This problem just occured. I had the 'computer guy' re-install microsoft 2003 and that is when this problem occured.
I've been through many websites checking how to solve and can find no solution. Will someone PLEASE write back to tell me how to solve this disgruntling issue?? Just respond to this post and I will check it frequently.yellowslugbuggy 'William Eyler' wrote: I am on COMCAST.NET and using Outlook or Outlook express I receive and ERROR message 550 5.1.0 Authentication required.

The Problem: All email that you send get’s bounced back with the following message: Subject Line: Delivery Status Notification (Failure) Message: Delivery to the following recipient failed permanently: [email protected] Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 #5.1.0 Address rejected [email protected] (state 14). The Cause: There is no “mail.domain.com” in the dns system.
In my case I was sending the mail via an alias (it was a notification email from the web server). The receiving mail server sees the email as forged and bounces it. The Solution: Go to the dns system and create a mail.domain.com and point your MX records to that. It’s a bit silly, but it has to be done that way.
Credit: This post originally appeared on the – with the absorption of Stronico into Digital Tool Factory this post has been moved to the Digital Tool Factory blog. We’ve just had the same thing occur – but in our case our mail service was added under an ‘asiapacific’ region rather than U.S.
There is also a ‘Europe’ smtp service. So we had to add new MX records (under Total DNS link from Domain manager) as: MX @ smtp.asia.secureserver.net (set to 0) MX @ mailstore1.asia.secureserver.net (set to 0) waited 1 hour and all ok. (if europre then its smtp.asia.secureserver.net) You can see the region for your mail account on the right side of the page in Account manager Manage email accounts. Hi All, I had the same problem with one of my hosted domains.
I created a few user on that hosting account and they were unable to receive emails from outside domains. I have an email form running on the website that uses gmail smtp to send out emails. The emails use different return path. Some emails get rejected returning the following error message: Delivery to the following recipient failed permanently: Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 #5.1.0 Address rejected (state 14).
Does anyone know how to fix this issue? Hi The recipient’s email address is valid. I just cannot send out via my google mail. Please teach me how to fix this. Message: Delivery to the following recipient failed permanently:. Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain.
We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 5.0.0 Reject spam mail (state 13).
Okay so i email my resume (attached) from my email address to several potential employers daily. I don’t have this problem with all of them just once in awhile. These are great companies to work for. Is it the attachment or the links in my email that sets them off? I am not using outlook yet, i direct mail from gmail. To their directs mails ([email protected]). I do not own the google domain and do not have sub email accounts.
So what say you now? Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 #5.1.0 Address rejected.
