Sounds like your personal email address is using the gmail work server to send emails.

Please post this information:

Hi Toad-Hall, thanks for making a suggestion. I hope this is what you are looking for below. I've done it for 'address 1' as I described it above. I assume this is what you want? Or maybe for both addresses?

Hi Toad-Hall, thanks for making a suggestion. I hope this is what you are looking for below. I've done it for 'address 1' as I described it above. I assume this is what you want? Or maybe for both addresses?

Address1 ? Both addresses? Third? Do you have any other setup then this with three Gmail and one Local folders?

• Account 1: imap.googlemail.com (Account-name not showing)
• Account 2: Local Folders
• Account 3: imap.googlemail.com (Account-name not showing)
• Account 4: imap.googlemail.com (Account-name not showing)

I have three addresses, I was trying to keep things simple by talking about the two I've observed to be an issue. They are a gmail account with 3 addresses, which I generally use through Thunderbird.

Sorry, was just wondering if you had another profile/setup beside this. This I don't want you to publish in here: Ones again open 'Troubleshooting information' but this time mark Include account names Make a note for yourself what account belong to what account - number. Any irregularities?

We need to check that each gmail mail account is using the correct smtp server.

'Tools' > 'Account Settings' or right click on mail account name in the Folder Pane and select 'Settings'.

Bottom left click on 'Outgoing server (SMTP)' In 'Outgoing Server (SMTP) Settings': You should have 3 Outgoing servers listed; one for each gmail mail account. Q: How many outgoing servers are listed?

Check each outgoing server:

'Description' - this can be anything you choose to help identify which account is using this server. eg: Personal, Business, Work etc

Each outgoing server should have a 'UserName' = email address/mail account that is using that server.

Use the 'Edit' button to modify anything, such as Description. Use 'Add' button if you need to add another outgoing server.

Example: if the top default outgoing server says the 'Username' / email address is the 'Personal' email address, select that outgoing server and click on 'Edit'. Type 'Personal' in the Description field and click on OK.

Then you need to check that your personal email address mail account is actually using that outgoing server. In left pane select the Personal email address mail account look on the right side near the bottom for the 'Outgoing server' it is using. Make sure it selects 'Personal' gmail outgoing server.

Repeat the same steps for the 'Work' email address/mail account. Look in the outgoing server list. select the Outgoing server that shows the 'Username' = the gmail work email address. click on 'Edit' and modify the Description to say 'Work' and click on OK. then check that the work mail account is using the Work outgoing server.

As you have three gmail addresses - I would repeat those instructions and enter a suitable 'Description', then make sure that third gmail acount is using that third smtp server.

When you are certain that all three gmail email addresses/mail accounts are using their own smtp server. Click on OK to save account settings.

Please test sending an email using the Personal email address.

Toad-Hall, Thank you! Problem solved, for some reason my personal address was using the wrong outgoing server.
