  If you are referring to my posts, what exactly is "a little irritating" about them?

  I think what they're trying to convey is when a company's name is attached, it's a little irritating. When it's a general question, e.g. : "I'm having trouble with my SMTP and Gmail" and then you mention your setup involves MXRoute I don't believe they would have found it "a little irritating" but when you said "Problems with attachments WITH MXROUTE" - that is basically obligating @jar to respond so he doesn't look like an ass to people who may be browsing.

  Does that make sense?

  One situation involves general input from anyone who cares to comment whereas the second situation is kinda putting @jar on the spot and would probably be more suited for a ticket that a forum topic.

  Yes it makes sense, thanks. That I can understand. I should have chosen a different title because my intention was not to imply that there was necessarily a problem with the MXRoute service itself. I will try to do better next time. Sorry to @jar if it sounded like that.

  So valid question.
  As for person, very good, great development for k8s in hetzner cloud.

  Thanks ❤️

  If your emails are successfully sent and received via Gmail without attachments but fail to deliver when you include a file, there could be several reasons for this issue:

  1. Attachment Size: Gmail has a size limit for attachments. If your total email size, including the file, exceeds 25 MB, Gmail will not send it. For larger files, consider using Google Drive or another cloud service and share the link in the email.

  2. File Type Restrictions: Gmail blocks certain types of files, especially executable files (like .exe) or files that it deems unsafe. Check if the file type you're trying to send is allowed.

  3. Spam Filters: Sometimes, including an attachment, especially from an unknown sender, might trigger spam filters. The recipient's email server might be marking your email as spam.

  4. Email Client Issues: If you are using an email client (like Outlook or Apple Mail) to send emails with attachments through Gmail, there might be issues with the email client itself.

  5. Network Restrictions: Some networks, especially corporate or public Wi-Fi, may have restrictions on sending large files or certain types of attachments.

  6. Server Issues: Rarely, there could be an issue with Gmail's servers, although this is less likely if other emails are going through fine.

  7. Incorrect Email Address: Double-check the recipient's email address for typos. An incorrect address can lead to failed delivery.

  To troubleshoot:

  • Try sending a different file type or a smaller file to check if the issue is with the specific file or size.
  • Check your "Sent" folder to see if the email appears there. If it's there, but the recipient didn't receive it, they should check their Spam or Junk folder.
  • If using a third-party email client, try sending directly from the Gmail web interface.
  • Review any error messages you might receive, as they can often provide more insight into the problem.

  If none of these steps resolve your issue, you may need to seek further assistance from Gmail Support.

  It's really weird because last night when I posted last time, it seemed to work even when sending via MXRoute, then I stopped receiving those emails in Gmail while I was sleeping. So I tried now again a couple of times, and it worked only when I sent the email via Gmail's SMTP service but not MXRoute, however emails sent via MXRoute reach other mailboxes just fine. The annoying thing is that Gmail doesn't even show the emails in spam if it's due to filtering.

  Yet, there is thread: "Looking for a small, cheap VPS just for Uptime Kuma. 1 core, a couple of GB of RAM"

  Seems logical one would use Hetzner and be done with it in 2 minutes, no ?

  Most of my stuff is on Hetzner (apart from some things in BeroHost at the moment). Do you usually have monitoring with the same provider as with the services you run? I definitely dom't.

  Why would you run your monitoring stack on the same provider you run prod on? That's just silly.

  Exactly.

  If you are sending to your own Gmail, it's best to connect to Gmail IMAP server and authenticate as yourself and then send to yourself.
  MXroute shall be used only after Google deadpools.

  I tried with Gmail's own SMTP and I see the emails in the inbox so it's progress, but I cannot download the attachment because it thinks it "contains a virus or blocked file", which doesn't make any sense. I even checked with VirusTotal out of curiosity and it comes clean. I'll see if there is some specific file extension or something that can trigger this.

  Is your gmail account new? Most gmail users would have ran into this attachment limitation a decade ago. I mean, you tell us gmail explicitly told you the problem and that you'd search that problem. So maybe people like amarc are wondering why your google search to resolve this yourself didn't run into something like this before (so it comes off like you're not trying before asking for help).

  Don't you have a bunch of self hosted methods to transfer files besides emails?

  Obviously I did search before posting and I also saw that page, and didn't post here right away without trying anything. Please stop assuming that. The archive I am attaching to the emails doesn't have any blocked extensions and doesn't contain any malware. I also checked with VirusTotal to see if there were false positives with some AV engine and there was nothing.

  Instead of using tar or gzip file extension use zip compression and let us know whether it works or not.
  I dont remember when but i also had problem with sending tar of gzip file. I used the zip compression instead and it worked fine.

  Try to do the following:
  1. Send this file from your own Gmail to your Gmail (same address to same address)
  2. Send from another Gmail to your Gmail (from different Gmail address)

  If you get delivery in 1, and bounce in 2 - then it is false positive. Life hack

  If not, then something with mxroute (maybe change this mail id).

  I tried, didn't seem to make any difference. At the moment it seems to be working again using Gmail's SMTP and it's not blocking the attachment again.

  I am a bit confused about the email id. Is it something I can change myself? Doesn't each email get a different id each time?

  If you face the problem again try using single compression. Compress the file once as zip and try sending it. May i know how much is the file size? If the file is too big sometime gmail causes problem. I dont think it has anything to do with MXroute.

  It's a directory of files zipped or tar-gzipped (depending on the test) once. I was wondering also about the size, but the archive is around 950Kb so not even 1MB. What I could find searching suggests that the limit is 25MB.

  if both work, then it is not related to your files. Files are good.

  I thought this was pretty clear:

  To protect your account from potential viruses and harmful software, Gmail doesn't allow you to attach:

  Certain types of files, including their compressed form (like .gz or .bz2 files) or when found within archives (like .zip or .tgz files)

  And you stated:

  Funny thing, a regular text file works. The attachment I am sending is a just a gzipped tar with some files.

  So I think other people would have made the connection sooner.

  I didn't digest all the minutiae here. Was a failure found at MXroute, Gmail, or somewhere in between? Did any resolution occur?
