Home Support FAQ Incoming Email

Why can't I receive email to Outlook Express, Eudora, etc?

There could be a couple of reasons for this:

  • Make sure you are using the correct ports and settings. For POP3, you should be using port 995 or port 110 with SSL enabled, and for IMAP port 993 with SSL enabled. For POP3 without SSL encryption, you can use port 112. 

  • You could be trying to log in to the wrong servers. If your account was originally on the US servers, you won't be able to log in to the Swiss servers, and vice versa. The (formerly) US servers are at neomailbox.com while the Swiss servers are at neomailbox.net. Make sure you're using the correct server name in your mail program's configuration.

  • Your account may have expired or been disabled. If you can't send mail or log in to the Control Panel either, it's likely that your account has been disabled. If this is the case, contact support for more details.

If you're able to send mail and access the Control Panel, but unable to retrieve your mail, contact support and we'll look into it asap.


I can log in to my account but I'm not receiving any new mail. What's up?

Your account is most likely over its mailbox disk quota. You can check your disk usage in the Control Panel for your account, which can be accessed from the Control Panel Login box here.

You should have received a warning email when you were getting close to your mailbox disk limit. Note however that fake messages about mailbox disk space limits are a common phishing tactic, and you should never click on any links in any such message. The legitimate disk quota warning message will not ask you to click on any links.

If you're able to log in to your account, but aren't receiving new mail, check your disk usage first. If your usage is over quota, new messages cannot be delivered to your account. To ensure that messages can be delivered to your account, you will need to either remove some messages from your mailbox to free up space, purchase additional disk space, or upgrade to a plan that includes more disk space.


Why did I receive spam from a Neomailbox address?

To prevent the abuse of our service by spammers, we limit how many mails our customers can send out per hour and per day. The default limits we impose are more than enough for most regular email users, but nowhere near enough to be of any use to spammers. Because of this, it's very unlikely that one of our customers would be sending you spam.

What's much more likely is that the headers of the mail you received have been forged to make it look like the message came from a Neomailbox account. But if you look closely at the complete headers of the mail, you will notice that the mail did not originate from or pass through our servers.

If you receive any spam that appears to be from a Neomailbox account, please do forward it to This e-mail address is being protected from spambots. You need JavaScript enabled to view it (with complete headers intact). We may be able to glean some information about the real spammers from such messages.


How can headers be forged?

It's trivially easy to forge a "From:" or "Reply-To:" header, as most email programs allow users to specify these headers themselves. The ability to specify any "From:" header can be quite useful, enabling you to, for example, use our secure SMTP server to send mail with the From: address set to your home or work email address.

Other headers that are harder to forge include the "Received:" headers. While these can be quite misleading as well, they are still normally quite useful in identifying the real source of an email message.


I have a huge mail in my account that I want to delete and not download by POP3. How can I do that?

Using our webmail system, you can delete big emails from your mailbox to ensure your POP3 mail client doesn't try to fetch such mails. You could also move them to a different folder using the webmail system, which will also prevent them from being downloaded by your email program.

Many email programs also allow you to set the maximum attachment size to download when retrieving messages using POP3. With a reasonable limit set for this parameter, you should be able to avoid downloading large attachments.
