Frequently Asked Questions

What is the capacity of my mailbox?

Theoretically it is unlimited: so far, we have trusted our users common sense, and we expect a certain degree of self-management and responsibility by our users, who should know that our project is totally managed on a volunteering basis and is only supported by our users donations.

Are there any limits for attachment sending?

Yes: about 10Mb incoming and outgoing.

I’ve received this error message:

4.7.1 : End-of-data rejected: Recipient limit exceeded. Please check the message and try again. what does it mean ?

It means that you sent too many messages, so your account is temporary blocked. Limits are:

100 recipients in a day


10 messages sent in an hour

If you are using your mailbox to send mails to a lot of recipients maybe you should ask us of a newsletter or a mailing list service.

What mail client do you recommend for windows?

The tools we advice are all licensed as FOSS, usually under a GNU/GPL license The mail client we most recommend is Mozilla Thunderbird.

How shall I configure a mail client to receive and send mail?

You can find the connection parameters here. For details about configuration, see out mail howtos.

I’m receiving a lot of spam. What’s happening?

We do use some anti-spam filters, but they are never exact. Apart from being patient, you could use the spam filters available with several mail clients, for instance with Thunderbird. And be sure that you have a filter that move the spam into the spam folder (see filters)

Valid messages are marked as spam, why ?

Send us (write to the complete headers of the message, hidden headers X-Spam-Status and X-Spam-Report explain why a message is tagged as spam.

How come do I only manage to send messages to and/or mail addresses?

If you’re using a mail client, probably you aren’t using SSL correctly to connect to our SMTP server, probably you are using port 25 for smtp server, which is wrong.

Check your client configuration with our mail howtos.

I’d like to open a mailbox on A/I’s servers. What should I do?

Go to the dedicated web page and sign in.

Will you send me spam and/or marketing messages?

No, we won’t. Despite our antispam filters, you’ll receive spam anyway. The only thing we can assure is that we won’t give away (either for free or for commercial purposes) your mail address. But, as usual, we recommend you to be cautious yourself, when giving your address around.

May I use my mailbox for commercial purposes?

If you use your private mailbox for your work, we have no problems (also because we never control the content of e-mails); but if you want a free mail address for your job and you’ve bumped into this project by chance, then our answer is No.

For further information, read our policy and our manifesto.

Is my mailbox content safe, if I leave it in the server?

No, it isn’t. As any other server, also our servers can run into accidents that could undermine its security.

Besides, unlike other servers, our servers are potentially more under control. For instance, the content of your mailbox is encrypted automatically with a personal key related to your user, that makes your mail unreadable even to us.

We do our best to protect our users' privacy, but this could be insufficient.

We therefore always invite everyone to download their mail and every other data and/or to encrypt their archives.

I can’t login in the webmail, I got an error about wrong user or password.

Be sure that the username you are using is your complete mail address.

If you forgot your password, try using the recovery password that we recommended you to set up.

If you don’t have any of those, there is no way we can help you (we never asked you your name or telephone number so it is practically impossible for us to know if you are actually the owner of a certain mailbox).

Verify that:

Probably it has been deactivated, send a mail to and ask for re-activation (remember to use a different email address in the request).

Are you sure you have not download them with a client ?

Or maybe your mailbox has been moved to another server, and mail are syncing, check our blog for news

Anyway, remember that we do not keep backup of your emails, so if your emails are so important, download them with a client.

Probably you are using a password longer than 63 characters, or strange characters. Choose a shorter password and avoid weird characters.

I’ve forgotten the password of the mailbox.

We do not keep track of who request a service, so we can’t know if you are the legitimate owner of the mailbox. If you haven’t set or don’t remember the recovery question we can’t help you.

No, but you can create an alias in your user panel and set it as default identity in the webmail/client.
