[Oberon] RFC 5322 and ETH Oberon SMTP.

[Joerg]

Peter

You said „some“. Do I understand correctly, that not ALL emails are bounced? In other words: is it a sporadic effect?

Did you investigate what is special with the bounced emails?
- are they longer than others?
- do they have one or more receipients?
- do they have long attachments?
- when you close and reopen A2 does the same email bounce again?
