Nope, no thanks. Besides the fact that it is apparently lacking some style (of programming) it just did not work. I tried it with IMAPs and SMTP/TLS. Nada.

Did not work after six tries and three different names.

It worked for me fine for my Gmail accounts. However, lacks some useful features. But for a such a small email client, it is okay.

Has never worked and now it appears here. It started to work then died. I've been trying to get the authors attention but it falls on deaf ears.

Koma-Mail works, is small (less than 2 Mb after UPX compression), is SSL (Gmail) and HTML capable, includes an RSS reader and has many useful features, but I just could not get used to the ergonomics of the program.

Looks: standard windows, but there is just something that makes it look uglier than normal windows. Windows: pops up at the wrong time, in the wrong place -- just a bit bothersome. Finally, there is something buggy about the display. Most of the times, when I drag a message from the message window to a folder, everthing works fine. About 30% of the time, the display encounters problems and leaves remnants of the cursor everywhere...

In summary, it works, but is "unrefined".

Koma-Mail worked great for me, a little slow but worked great, really nice spam filter, and easy to use interface that works just fine with my email provider (www.gawab.com) FYI: Yahoo is not a pop3 Email unless you pay for the premium.

Great little Email client once you get used to it.

Oly ting missin is spell checkin...

Aaron 2007-11-24 09:39

hey Zera, check out YPOPs! (not portable ?) if you want to grab Yahoo email into email client ... though it's not always smooth with installed Outlook Express. Assuming it'll work with Koma-Mail, never tried ?

No version of Koma mail has worked for me since v 3.59
I do like it however. Installing the newer versions in the original directory caused apparent loss of data. When the original was re-installed to the same directory, the data re-appeared. Keep your originals, and install updates to a new directory for testing.

I can't understand all these negative comments. I tried Koma-mail after a lot of other software (foxmail, thunderbird, eudora and so on) and I think it's very easy and confortable to parametrize and use.
It's not heavy, not annoying, not hard to use (have you never seen Mulberrymail ?). When I needed a personalization I wrote in the forum and the author was very kind to find a solution and to send me a beta compilation to test it.
I decided to install it on all my pc (Xp and W98), not only on pendrive, and with all my mailboxes (I work with 37 different mailbox accounts). Now we are trying to add or modify many other features and our dialog is very nice.

If I read the popularity score it is the higher after (the heavy) Thunderbird, and if I read abuot your comments they are all negative and absolutely contrary at my test and opinion. I thing it's strange . . .

I think KOMA developed much from the 1st comments from 2006. I have tried it and loved it (Gmail - IMAP). Most of all is free & portable.

Jay 2008-09-11 22:46

This email client is working faster than thunderbird usb. It is nice but needs soem enhancements for example in speed. For such a small client, faster performance is expected like Mini mail.

I don't know if you can call these bugs but they are more like annoyances of trying to break the application.I found that I had to delete the Default folder in the locales folder because it was automatically using Default and not English

John 2010-02-28 21:13

I use this as my desktop client at home. Not super advanced, but seems fast enough compared to thunderbird.

Kea 2013-02-02 15:16

A tip in Koma-Mail says: "When using Koma-Mail in offline mode (can be selected in the main window), you can prevent mails having access to web contents (webbugs)."
Do anyone know how to select that?

I downloaded Koma-Mail to run on my pendrive. I've had a couple of minor irritations which I sorted out. My problem(s) are:
When importing eMail address's from a CSV file it isn't comma separated it's more semicolon separated. When the import is done I found that, when composing an eMail, if I start typing the name of the recipient it starts to anticipate name but it puts in the name and then the eMail address, so you have to clear part of the entry or it fails to send. You can open the address book and tick the boxes then it works.


Technomancer 2014-12-07 20:28

I've been using Koma-Mail for a week or so now and I found that its one of the best FREE Portable eMail Clients that I've tried. It's a little quirky, for example importing email addresses from a CSV file. You have to open the CSV file in a text editor and change ALL the Commas to Semi-Colons and that's it.
The authors web page seems to have been 'unavailable' for some time and I've tried to send feedback as well.

I haven't had any 'Donate' messages but if I do get one I'll gladly make a donation.

I've written a couple of little menu utilities but I haven't had any donations yet. If I find a good little program that I like I usually make a donation because the author should get something for their work.

Hi Kea, I just took a look at Koma-Mail v3.83 and I can't find ANY obvious way to switch the ONLINE mode on or off. I downloaded the user manual, (web pages), and can find 2 references to it but no means of doing it. I also sent an email 'Koma-Code' but haven't had a reply as yet.

Still, it seems to be working anyway.


Technomancer 2015-01-26 20:44

OK. I'm still using KomaMail and I still like it. I've set the 'Check Mail' time to 5 Minutes but it does't seem to automatically check at all.
If anyone CAN contact the author I think Komamail is well worth continuing to develop it and with the feedback from this forum it could be excellent.


Technomancer 2015-01-26 20:55

I forgot. It's a shame that KomaMail isn't Open Source then someone could 'debug' and develop it. The athors web page doesn't seem to have been updated since 2004
