IMPORTANT
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, ResellerClub allows you to use an alternate port 2525 for sending mails if port 25 is blocked -a. In Mozilla Thunderbird, on the Tools menu, click Account Settings.
b. In the Account Settings view, the email account configured is listed. Click on Outgoing Server (SMTP).
c. In the Outgoing mail (SMTP) Settings section as seen in the above image, replace the default port number 25 with the alternate port number 2525.
