Sometimes an outgoing mail server can conflict with the computer’s protection systems.

Gmail provides free webmail accounts and POP, IMAP and SMTP servers. Here’s a list of all the SMTP error codes to get your bearings and remember again that using a professional outgoing server this won’t happen again. This article was written for Thunderbird but also applies to Mozilla Suite / SeaMonkey (though some menu sequences may differ). Now this is trickier: even if your SMTP details are correct, the server itself can be down or not functioning for some reason. Another small mistake that happens usually, so doublecheck your login details. Once you click next it will verify the details are correct and add the account. Then click ‘Add Account’ > click ‘Other’ from this list > click ‘Add Mail Account’. To find out yours, please refer to our list of the most common ones or ask directly your provider.

If you can’t send your emails, the problem is very likely (but not exclusively) related to your SMTP server – the server taking care of the whole email delivery process. You open your favorite mail client or software (Mozilla Thunderbird, Outlook Express, SendBlaster…), write a few lines, insert the recipients’ addresses, click “Send” and… An error is returned. Sometimes it happens: you simply cannot send emails.
