Postfix timeout after data MTU size question

We use postfix as a mail queue / sending service in one of our applications. This application generates emails with PDF attachments. Some of the emails with PDFs get sent fine, but others seem to cause a "timeout after DATA" error. Through reading online, I've seen answers such as adjusting the MT

That log entry says the message was successfully delivered to your relayhost, and is normal. From that point, it's the relayhost's responsibility to either deliver the message or return it if it's not deliverable. The next line in the log probably says queueid A710260D2F removed, which is also no

Thanks everyone. I removed domain.com and local.domain.com from mydestinations, and set relay_domains = domain.com. Suddenly, everything started to work! My logs say that outgoing emails have a status of 252.0.0, in case that's anything I should worry about? On Wed, Sep 21, 2016 at 10:02 AM, Noel

I use check_sender_access and DISCARD to throw away about 1500-4000 messages a day from .top domains (which is about the volume of my legit email). I looked into it and most of them are registered to namecheap.com, which appears to sell the names for for $.98 each. I did a little research into
