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, Whois.com Pte Ltd
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. Click on Outgoing Server (SMTP).
In the Outgoing Server (SMTP)
Settings section as seen in the below image, select entry for your
domain name and click Edit.
c. Replace the default port number
25 with the alternate port number 2525.
d. Click OK in the SMTP Server
and Account Settings windows to save the changes.
