Mail client setup

To connect your local mail client with your AltMail.se account, you need your primary account email, your secret password, and the information below. (Certain clients, such as Thunderbird, are smart enough to auto-detect the mail server configuration by requesting and parsing a standard service descriptor as well as SRV service labels from DNS. Other clients require manual setup.)

We provide standard IMAP and SMTP access over secure (encrypted) channels. The below configuration information is applicable to all email clients that lend themselves for usage with such a (standard) email account. You will need to locate the account configuration dialog, config file, or similar mechanism specific to your email client application that lets you enter this information. Please consult the relevant software manual, documentation, or your local guru for help with your specific email client.

There are two standard protocols involved in connecting to any email account, and AltMail.se is no exception: IMAP is for accessing the mailbox (navigating folders, downloading, moving or deleting emails) and SMTP is for sending outbound email. Both must be correctly configured before your email client is able to access your account.

Please note that we do not provide any support for the POP3 protocol. If this is a problem for you, please consider upgrading your email client.

IMAP

• Server: imap.altmail.se
• Port: 993
• Transport security: SSL/TLS
• Auth method: PLAIN (normal password)
• Login: youremail@altmail.se
• Password: your secret password

SMTP

• Server: smtp.altmail.se
• Port: 587
• Transport security: STARTTLS (mandatory)
• Auth method: PLAIN (normal password)
• Login: youremail@altmail.se (*)
• Password: your secret password

(*) Note that the email address to use for SMTP authentication is always your primary account address, even if you are sending out email from an alias address. The email headers prepended by our mail exchanger will not give away your primary address. Technically speaking, the Authentication-Results header fields will include smtp.mailfrom (showing your alias address), but not smtp.auth (which would contain your primary address you authenticated with).

To manage your collection of server-side Sieve filters, direct your Sieve client to our ManageSieve service as specified below. See Server-side filtering for some tips on client programs to use.
