Can't Send Mail - Netscape | Mozilla | SeaMonkey

A few workarounds to try:

First: Back up your Profiles Folder

With the browser closed:
Delete the XUL.mfl file
This file is located in your *.slt Folder located here: Profiles Folder Location
Delete the Sent.MSF file. DO NOT delete the Sent file with no MSF extension, as it contains the mail
This file is located in your Mail Account folder

If this doesn't help, then move your Sent Mail files to a temporary folder, then exit the browser, open Windows Explorer. Navigate to the Mail Account folder. Delete both the Sent, and Sent.msf files. Restart Netscape... Did this work, can you send now?

If not:

Check the SMTP server settings for each Mail Account, found under:
Edit | Mail & Newsgroups Account Settings | Outgoing Server (SMTP Settings) | Advanced
Ensure there is no blank space that highlights, if you click on the blank space above the SMTP server names, or below the SMTP server names. Remove any duplicate server entries.
See Screen Shot

Highlight each Mail Account name in the left panel of your Mail window
In the right panel select: "View settings for this Account"
Click the Advanced button. Ensure that the setting is: "Always use Default server"
For Mozilla 1.6, 1.7, and 1.8, highlight "Server Settings" to access the Advanced button.
See this Screen Shot

Also check your preferences in about:config

Clear the Location Bar field
Type this text in the blank field: about:config
Using Netscape 7.1, scroll down to this setting: mail.smtpservers

Using Netscape 7.2, Mozilla, or SeaMonkey
In the blank "filter" field type this text: mail.smtpservers
Highlight the setting, and right click
If there are duplicate SMTP servers, then select: "Modify"
Remove the duplicates and close the window
Exit the browser
This edit will now appear in the prefs.js file
Always back up the prefs.js file before editing.


Check your "prefs.js" file. Do your entries look similiar to this:

user_pref("mail.smtpservers", "smtp1,smtp1,smtp1,smtp2");
Remove the duplicates in the "smtp1,smtp1,smtp1,smtp2" string so it will look like this:
user_pref("mail.smtpservers", "smtp1,smtp2");
Close the browser and Quick Launch before editing the "prefs.js" file. Back up the file before editing.

You might also try this:

Add a fake SMTP server and make it the default. This will allow you to delete the problematic SMTP Server. Remove them all, and re-start Netscape. Then re-enter the real server data, and make the "real server" the default, then remove your fake server.
