Email sending issue on port 25




Email sending issue on port 25


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, you can use an alternate port 26 for sending mails if port 25 is blocked. Here's how:

In Outlook 2003

a) In Microsoft Outlook 2003, on the Tools menu, click E-mail Accounts.
b) Select View or change existing email accounts and click Next.
c) Select the email account you wish to modify and click Change
d) In the Internet E-mail Settings section, click More Settings
e) Under the Advanced tab, replace the default port number 25 with the alternate port number 26 in the field provided for Outgoing server (SMTP)
f) Click OK, Next and then Finish to save the changes.

 

In Outlook 2007

a) In the Tools menu select Options -> Mail Setup and click Email Accounts
b) Select your account and click Change above the list of accounts
c) Click More Settings and then the Advanced tab
d) In the Outgoing server(SMTP) field replace the default port number 25 with the alternate port number 587
e) Click Ok -> Next -> Finish -> Close and then Ok to save the changes

 

In Mozilla Thunderbird

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 26
d) Click OK in the SMTP Server and Account Settings windows to save the changes.
