so after lots of struggling with the #ssh configuration @lkh and me managed to establish #usenet peering between his machine and mine, over #uucp

now we need to get someone to actually deliver news from the wider #usenet to us.

@lkh as I said, the idea is simple, getting it working isn't. there are a lot of small working parts that need to be configured right.
like the passwd file needs to have a tab between username and password, where everywhere else a space is enough.
and of course the documentation is spread over at least 20 year old files all over the net.
it's not like many people are enthusiastic about this particular technology (because lets face it, for is superior, for email it's )

Current status: cup of tea in the garden. Reading a 2007 book I bought in 2012, about some software first released in 1995 handling a 1981 protocol that I'm going to use as the cornerstone of my teeny tiny SaaS in 2024.

May we all have such a long-term effect on the world!

If you use forwarding actively, HEADS UP.

is now enforcing policy and as of midnight last night is bouncing email from ACM.ORG addresses that did not come through the ACM Relay service.

You need to change your email configuration to use the ACM SMTP Relay service immediately.

Here is a link for how to configure your mail service (including GMAIL) for the Mailroute SMTP Relay.

Anybody knows where to get good Internet traffic statistics these days? I'm interested in the protocol mix seen in the backbone, not absolute numbers.

What percentage of the traffi is #HTTP, #HTTPS, #DNS, #SMTP, #IMAP, #FTP, #SIP, #RTP, … these days?

#Caida had some traces, but the latest I know are from 2012, which is not helpful.

Oh what joy. Seems like #Mail.app on #iOS no longer allows sending uncompressed 2.2 MB JPEGs.
My #SMTP server advertises 250-SIZE 157286400 (accepts messages up to 150 MB) and base64-encoded 2.2 MB binary would weigh roughly ~2.86 MB.

What non-3rd party options are there to transfer pics from #iPhone to #FreeBSD laptop nowadays?

Every so often, I need to chase down some aspect of email validation (#SPF, #DMKIM, #DMARC, ...). This involves a number of #DNS records and queries, but I may forget just which ones. So here's a quick #SMTP/DNS cheatsheet:

Solved e-mail not working in luckyBackup app with smtp-cli app

In principle, I support the use of #OAuth2 for #IMAP/#SMTP authentication; I just wish it didn't make it so much harder to use my preferred mail clients for corporate #email accounts because each client's OAuth2 app key needs to be approved by the sysadmin.

Currently cranky that I can't use Mutt with a couple of O365 accounts, and wondering if I can do something sneaky like rip OAuth2 keys out of Thunderbird or something.

Apas: ActivityPub via email

https://apubtest2.srcbeat.com/apas.html

The overarching goal is an experimental system to make ActivityPub federation stuff clearer for devs, sysadmins and advanced users.

The documentation is incomplete and the code is really not OK! But they always say it's better to get stuff out the door for others to look at sooner. Maybe it inspires others to think about the Fediverse/ActivityPub in weird new ways!

PS thanks @emersion for your SMTP work!

Timo Longin @login introduces SMTP smuggling, a novel technique to spoof fully SPF-validated emails from various popular domains including @microsoft.com.

Wow. It's incredible nobody found this before. It's the first of its kind. Probably not the last...!

OK folks, I'm in need of a tech assist: Please Boost!

Any Mastodon Postfix and/or ISPConfig wizards out there? I am trying to figure out a problem with the smtp not sending, possibly due to a bad milter/rspamd communication.

Trying to avoid a reinstall.

Thanks!

An experimental and interface.
I feel like interface would be more appropriate.
But gotta start somewhere!
Threading and replies work ok too (so far!).

After this week's Spring Break, we return in my #SysAdmin class to dive into #SMTP.

We start with an overview of the ecosystem consisting of MUAs, MTAs, MDAs, Access Agents, and tcpdump a simple manual SMTP session over telnet. We then talk about STARTTLS, MTA-STS and #DANE, before diving into #spam defenses, including #SPF, #DKIM, and #DMARC, all with practical examples, tracking lookups and traffic on the sender and receiver.

I've been doing more research on email servers and email hosting.

It would be great to talk with a Sys Admin who handles email for multiple domains and clients.

I am working with a company who has been doing web design and hosting for their web design clients since the '90s.

They hosted their email starting way back when and have been using the same email server pretty much ever since. It needs to be replaced soon.

The question is what to replace it with.

Host our own? And all the complications that come with that.

Manage the email but host somewhere else with a company that specializes in email? Such as MXroute:

https://mxroute.com

Host our own email IMAP accounts, but use a separate service for sending mail so we don't have to worry about deliver-ability?

Let me know if you have experience with a similar situation.
