mutt, IMAP, and Exchange (patch)

kant1 · 2008-11-22 16:43:56

Just wanted to let anyone interested know that I was able to get mutt working with an Exchange server over IMAP.

You can find out more here: http://mychael.gotdns.com/blog/2008/11/ … -exchange/

I've already put the package for libntlm out on AUR. Here is the patch to the mutt package (ie. extract the mutt tarball and apply this patch):

This looks very promising; i would love to get my work and google mail all though mutt.

one comment though:

on your site, under your Gmail settings you have

set record='+[Gmail]/Sent Mail'

i've see this same setting in every single mutt/gmail sample config on the internet.

google's smtp server automatically saves a copy to "Sent Mail"; with this setting you'd end up with duplicate copies all through your "Sent Mail" folder (i did). to prevent this behavior i use this setting in stead:

unset record

kant1 · 2008-11-25 20:42:33

Thanks for your constructive comment!

I just checked, and strangely, I don't have duplicates in my Sent Mail folder. I wonder why the difference?...

brisbin33 · 2008-11-25 21:33:48

interesting indeed:

from http://mail.google.com/support/bin/answ … opic=12920

Google Help wrote:

Sending:
* Do NOT save sent messages on the server. If your client is sending mail through Gmail's SMTP server, your sent messages will be automatically copied to the [Gmail]/Sent Mail folder.

as well as my own experience i can't imagine why you (and all the other tuturial writers out there) aren't having the same problem.

oh well, more to the point; i'm excited for exchange support !

Good point. If you want to make a comment posting at the site above, that would be great. If not, no sweat. But it looks like you do have a very valid point, and the documentation to back it!

I'd be interested if the instructions help you or if anything is unclear.

My current set up is really slick, and much better than the fetchmail+mutt solution I've had for the past couple years. I hope you'll like it too!

brisbin33 · 2008-11-25 22:50:05

yeah, i definitely plan on looking into it shortly; i've never patched a program before but i hear it's not hard. i need to check with IT and see if our exchange server supports IMAP; my last job did not.

i've bookmarked you're site and i'll comment if i can get it going. thanks again for the info.

EDIT: my company blocks external IMAP connections too

}

+ uploaded libntlm 1.0 (stable) to AUR

cant test it cause it seems like our company has IMAP disabled on our exchange

kant1: can you add " provides=('libntlm') " to your libntlm-git PKGBUILD?
