Follow the steps detailed below to use Eudora to send/receive mails.
1. Start Eudora and on the Tools menu, click Options.
2. Under the Getting Started section, type the name that you want others to see when you send a message, in the Real name field. In Email address, type in your email address which should be of type user@yourdomainname.com. You need to mention the Mail Server (Incoming) as pop.yourdomainname.com or imap.yourdomainname.com depending upon the type of account (POP or IMAP) you wish to set up. Mention your complete email address in the User Name field. The SMTP Server (Outgoing) address in any case will be entered as smtp.yourdomainname.com. Check the Allow authentication checkbox.
3. Select POP or IMAP under the Incoming Mail section according to the server you have specified in the previous section. Then click OK.
4. Under the File menu, click on Check Mail and provide the password for your email account to download the messages.
Usually, the port used for the Outgoing Mail Server/SMTP Service is 25. However, there might be a situation where your ISP might be blocking the use of port 25 for SMTP service. Many ISPs block port 25 in order to minimize the amount of spam sent using their network. If you are facing issues sending mails using the default port 25, you can confirm with your ISP whether port 25 is indeed blocked by them.
To circumvent this, Dinsol.Co.In allows you to use an alternate port 2525 for sending mails if port 25 is blocked -
a. Close the Eudora client.
b. Locate the directory in your computer where Eudora is installed. The directory path would be something like C:\Program Files\Qualcomm\Eudora.
c. This directory has a folder named extrastuff, which has a file esoteric.epi.
d. Drag this file into the main Eudora directory.
e. Start Eudora and on the Tools menu, click Options.
f. Under the Ports option, enter the alternate port number 2525 in the field provided for SMTP Port.
g. Click OK to save the changes.
