Hi,
I use IONOS 1and1 for email.
This week, I haven't been able to send emails with attachments to gmail addresses.
I've had this problem once or twice before, then it went away after a few days.
Everything appears fine on my end, so I believe gmail is blocking these emails for some reason.
1. I don't get a bounce-back message that my send failed
2. The gmail users do not receive in the messages in their spam folder,
or any other indication the message was sent to them
3. This ONLY happens when the email has an attachment
4. I tried sending with my VPN disabled, but that didn't help
I read Google's advice about when sends to email users fail at
their webpage. But it did not help.
Any suggestions? Thank you.
