it was a bomb.

Google does seem to be using artificial intelligence a lot. Your posts
on the thread mentioned 0.45 calibre bullets as examples of the quantity
of stored energy you were dealing with. It's not one I've ever seen
any other electronic professional use. It might have been enough to
trigger its anxieties.
Somebody else suggested that a pitched baseball was in the same
ballpark. A much less threatening example

Just don't use Google for anything serious, especially
email. Assume disposable resource that could go down at
an time. They also don't like compressed, or binary

A man at Dublin-City University posted to a DIY-explosives USENET
newsgroup decades ago complaining that persons who contribute to that newsgroup are dangerous because e.g. the Irish Republican Army could
study that newsgroup to learn to make bombs. A consequence is
Dublin-City University disabled USENET accesses between the USENET and
most persons in this fake university.
"PC Format" (a magazine by Future Publishing) in the United Kingdom of
Great Britain and Northern Ireland called programmers for an American Internet-service provider idiots because this ISP blocked emails about Scunthorpe (a place in the U.K.) because a substring of "Scunthorpe"
is a word which they do not want clients to read.
A fool got 110/110 (i.e. 100%) in a degree in physics. He sent myself
an email via GMail. He requested me to not publish it. Even though I
had never logged into GMail, I had responded to him indicating that
Google advertising might be based on scanning this email. It is poetic
that physicist rhymes with fool.

I just paid the IEEE $US44 to maintain my IEEE e-mail address. It used to be covered by my membership which has been free since I
became a life member. I've got my own e-mail address tied to my web-site, but it doesn't go back as far.

I don't use gmail unless I want an address in public.
Since email started I have preferred to run my own email server.
For the type of email you're sending I'd probably use this: https://www.emclient.com/email-encryptionThere are several free mail services that offer end-to-end encryption. Personally, I find the use of an intermediate store more useful
nslookup -type=MX ieee.orgMany organizations have outsourced their email to google.

Still with Thunderbird, well, since it was originally
Netscape mail. Use Fasthosts (UK), for the domain name
and mailboxes, for most of ten years now. The isp, with
fixed ip address, just provides the wire. Pretty good,
100% uptime, since dumping BT, trying to rip me off on

I haven't been able to contact anyone who uses gmail or google mail for
a couple of years now. Apparently they are demanding some
identification which my e-mailer doesn't give, so they just delete my
e-mail without explanation. I am not going to change my e-mailer to
suit them, expecially if it gives them information I have no control
over.
Currently i have to send e-mails to gmail users by firat posting them
to another computer and then forwarding them from there.

Are there any happy stories of AI moderators/filters? I don't write reviews on
Steampowered anymore because of the AI moderators and also that they don't state anything about their criteria for refusal. I don't use reddit except for
in what i consider have to or necessary cases where I absolutely need to make a
statement because of their AI interceptors. I'm more open to reddit because their AI moderators make a brief case for their exception to your posting, but
still reticent and reluctant to post there except in extreme need. I have yet
to hear a story about someone proud of their AI interceptor at an internet location or website. Maybe the people in charge? I don't know.

Presumably, you don't have problems contacting other MX's so its
not a local block on 25.
Have you tried TELNETing to the particular MX server to see if
the connection is blocked? Or, possibly, just "deferred"?
Is your hosting ISP "dubious" and possibly blacklisted (not for
YOUR actions but for the actions of others at that origin point)

Is your host's DNS configured properly (esp PTR records)?

Outlook adresses block my messages from Friday afternoons until Monday mornings (the timing varies a bit) some weekends.

ALL outgoing messages? Or, just gmail?

I don't know how to do that.
# nslookup -type=MX gmail.com
This asks "your" name server to tell you the MX (Mail eXchange) record associated with "gmail.com" (the messages you can't seem to send).
It will produce a list of one or more fully qualified host names that
will accept inbound connections for mail destined for "gmail.com".
Each will declare a "preference" as to its usage (the lower the
preference number, the more it wants to be contacted -- use higher
number preferences if the lower ones are busy, offline, etc.)
This isn't a "privileged" operation; you are asking YOUR name server to
get this information for you (it may tell you -- your "resolver" -- to contact ANOTHER name server for the actual details, but the data is
publicly accessible)
# telnet <name_of_mail_sever_from_above> 25
This tries to connect to the named host on port 25 (which is the "well
known" SMTP port). If this *fails*/refused, then that host doesn't want
to talk to you (*there*).
If a connection is established (usually a 220 reply), the remote server
will expect you to engage in a series of protocol steps (the 'P' in SMTP)
to present mail messages to users in the domains it handles (gmail.com).
HELO <your host name>
MAIL FROM:<you or someone else>
RCPT TO:<some email address>
DATA
<message being sent>
CRLF.CRLF

Your MUA does this automatically for you when you send a message.

No idea.
As a crude security check, the mail server may take the IP address
that you connected *from* (which it knows while the connection is established) and try to map that back to a host name. So, you can't
claim to be someone/something else.

There are *countless* ways of "hiding information", especially if the bandwidth (or, total amount of data) is unspecified.
