DockerHub

[FireFtw]

Any interest/plans to maintain a docker image on DockerHub?

[the-djmaze]

I'm no docker user.
Maybe you or someone else wants to do that?

[FWest98]

I will be able to do so. @the-djmaze if you could send me an email I could arrange automatic docker builds for you as well.

Yes i hate Microsoft. Keeps blocking every few months.

Hotmail/Outlook's antispam is really, really picky indeed.

Make sure your HELO matches your dns setup, MX, and if possible reverse/PTR record.

And if you use SPF, include a plain A record IP there (in addition of, or in place of MX/include records).

@the-djmaze Now I'm wondering, did you ever receive my reply to your email?

[dawid-woitaschek]

@the-djmaze @FWest98 So, what's up with DockerHub?

[the-djmaze]

@the-djmaze Now I'm wondering, did you ever receive my reply to your email?

Yes, but i totally forgot to reply.
Sorry for that.

Any plans to release a docker image of SnappyMail ?

[r3pek]

I took the liberty of using their own Dockerfile and setup a build and upload the image to Docker Hub. Feel free to use and/or report sugestions/bugs

https://hub.docker.com/r/r3pek/snappymail

I don't know why people use buster as base 😞
I have one running on alpine (https://hub.docker.com/repository/docker/combro2k/alpine-nginx-snappymail/)
It's still a work in progress tho, source is https://github.com/combro2k/dockerfiles/tree/master/alpine-nginx-snappymail-php8
It misses some 'extras' but base image is 82.79 MB vs 228.17 MB from buster ;-)

[combro2k]

@the-djmaze I think your provider doesn't follow the guidelines,
It isn't microsoft's strictness :-P also you can add your IP from the provider (I would hide tho in the message)
to a whitelist :-)

Awesome!

OFF TOPIC:

It isn't microsoft's strictness :-P

@combro2k nope, it's Microsoft at fault.
There is a big rant discussion here in the Netherlands that only Microsoft is blocking IP's for no apparent reason.
A lot of hosting companies (small and big) have to unblock mail-server IP's every month.
Also there are cases where Microsoft servers respond with "mail accepted" but the receiver never received the e-mail (not even in spam folder).

Currently we all report this to the local and European Commission in the hopes that Microsoft will change their system to be compatible with SPF, DKIM and DMARC.

@the-djmaze I know you're from the NL as I am (based on the IP you shared) ;-)
I've worked at an ISP for some years, but yeah it's an fight we all have to go.
The most effective is indeed DMARC reporting, SPF & DKIM combination.
We had an cluster of (own hosted) spamexperts running which made that part a little bit complicated;
It was always an issue with them meh. But anyway back on the TOPIC :-P

Edit: I think the most issues are starting when you have multiple senders on the IP (different user/domains)

I've built the latest version on aarch64 using the Dockerfile in the repo without hiccups on a OCI VPS.
I haven't looked into the Alpine version but I'll try when I get some time.
If anybody is interested, the latest image is located here: https://hub.docker.com/r/fffrantz/snappymail

When I get around the Alpine version, I'll try to setup automated builds for both on aarch64.

Would also like to see this on dockerhub, @r3pek in the meantime do you plan to keep your image updated from time to time?
Thank you!
