SpamSieve works with macOS 10.13 and later, as well as pre-release
versions of macOS. For older versions of macOS, previous versions of
SpamSieve are
available.
Supported Mac Mail Programs
SpamSieve is designed to work with the following e-mail programs that are
currently under development:
- Apple Mail from macOS 10.13 and later.
- Airmail 1.3.1 (223) and later. Versions
3.6.3 through 3.6.41 are not compatible with SpamSieve on macOS 10.14,
but version 3.6.42 and later are.
- GyazMail 1.2.0 (1.5.8 or later recommended).
- MailMate 1.1.2 and later from Freron
Software.
- Mailsmith 2.3.1 and later from Stickshift Software. (By applying
this workaround
you can use SpamSieve with Mailsmith 2.1.5.)
- Outlook from Microsoft
Office 2011 (14.x) and later, including Outlook 15.x and 16.x from
Office 365. Outlook needs to be running with “New Outlook” turned off,
which it does not allow when running in free mode.
Outlook Live and other browser-based mail are not supported, except
via the Mac clients listed here.
- Postbox 2.0 through 5.x from Postbox, Inc.
Postbox 6 and 7 are not currently compatible.
Postbox Express and the (discontinued) Mac App Store version of Postbox
are not compatible.
- PowerMail 5.0 and later (6.x recommended) from CTM Development.
PowerMail only supports SpamSieve with POP accounts.
iOS Mail and Web Mail
SpamSieve does not run on iOS, but you can use it together with your Mac to
filter mail on your iPhone, iPad, or iPod touch. This is described in the
iPhone Spam Filtering section.
SpamSieve works with Web mail providers via Apple Mail. Please see the Setting
up Gmail, iCloud, Yahoo, AOL, or Other Web Mail section.
Supported Legacy Mac Mail Programs
SpamSieve also works with these legacy e-mail programs:
- Entourage v.X (2001) and later (Entourage 2004 or 2008
recommended) from Microsoft.
- MailForge 2.0.4 and later from Macsimize
Software (formerly from Infinity Data Systems).
Multiple Accounts/Addresses
SpamSieve filters all of your mail accounts. There is no extra charge for
additional addresses.
Multiple Mail Programs
You can freely switch between mail programs or even use multiple mail programs
at once. SpamSieve will share its training data and statistics among them.
Unsupported Mac Mail Programs
SpamSieve does not have direct integration with the following mail programs. You
can, however, still use them with SpamSieve as described in the Setting Up
Other Mail Clients section.
- Canary Mail is not sufficiently extensible
for us to connect it with SpamSieve. We have offered to help the
developers add support for SpamSieve, and they have expressed interest.
Sending them feedback (click the
blue-and-white icon at the bottom-right) will help them prioritize this
feature.
- MailPlane is not sufficiently extensible
for us to connect it with SpamSieve. Please contact the developers and tell them that
you would like to use SpamSieve with it.
- Mail Pilot is not sufficiently extensible
for us to connect it with SpamSieve. We have offered to help the Mail
Pilot developers add support for SpamSieve, and it’s on their to-do list.
Sending them feedback will help them prioritize this feature.
- Newton is not sufficiently extensible
for us to connect it with SpamSieve. Please contact the developers and tell them that you would
like to use SpamSieve with it.
- Spark is not sufficiently extensible for
us to connect it with SpamSieve. We have offered to help the Spark
developers add support for SpamSieve, and they have expressed interest.
Sending them feedback will help them
prioritize this feature.
- Sparrow is not sufficiently extensible
for us to connect it with SpamSieve. The Sparrow developers were
interested in adding support for SpamSieve, but the product has since
been acquired by Google and seems to no longer be under development.
- Thunderbird. Current
versions of Thunderbird have removed support for compiled plug-ins. However,
SpamSieve does work with Postbox, which
is an enhanced version of Thunderbird.
- Unibox is not sufficiently extensible for
us to connect it with SpamSieve. We have offered to help the Unibox
developers add support for SpamSieve. Sending them feedback will help
them prioritize this feature.
