Sometimes it happens: you simply cannot send emails. 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. Why?
There are several things which could be affecting your email:
Check your internet connection. Yup. It happens. So first of all, be sure that you’re connected to the internet!
Your email account is full. Log in to your online email access. Then try deleting any emails you don’t need – particularly those with large attachments.
An issue with your email software or device. Verify all usernames and passwords.
A large email is being sent
Large email attachments can cause your mailbox to lock, but it will unlock itself within 20 minutes. If the problem keeps happening, try deleting any emails over 3MB.
Check your SMTP server details. This is an extremely common mistake: you have set up your mail client with the wrong SMTP parameters.
Check your SMTP server connection. Now this is trickier: even if your SMTP details are correct, the server itself can be down or not functioning for some reason. 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.
Control your antivirus or firewall settings. Sometimes an outgoing mail server can conflict with the computer’s protection systems. So verify that your firewall or antivirus are not blocking it, setting up a proper exception rule.
