I am not sure that k-9 has a specific limit. But I sent things over 4 MB, perhaps even close to 20 MB, fairly often, with no trouble. I've been reading the k-9 mail list for years, and have not seen similar reports of trouble. Keep in mind that a 3 MB file is a 4 MB attachment, more or less, with base64 encoding. Mail servers have a configured size limit, as David said. But it would seem odd, these days, for 4 MB to run afoul of that. > I could not email an attachment of over 4 MB via public wifi nor via my own > home wifi. To debug this, you need to look at the server logs, and see what the server recorded. Also, set up adb and see what k-9 logs. You say "could not", but that is not specific enough. For people to help you, you need to be describe more details, including the timeline from pressing send and the precise error you received. You say "could not" about "public wifi" and "home wifi", but do not mention cellular, or anything else. Do you mean "I tried those two things, and can't readily try anything else, and I have never seen it work"? You didn't explain if regular text mail works, and if you have tried successively smaller attachments to find a magic size. Or if your mail provider has a mail size limit. You also did not explain if you have set up another email provider and tried that, or a different client (thunderbird on desktop) to see if that has the same issue. > Strangely enough, those emails were removed from the Out map into the Send > map.

The message going from the Outbox to the Sent folder is not proof that they actually were sent, but evidence that k-9 thought they were accepted by the first-hop server. Overall, I suspect you will find a problem in the email service (or perhaps a network which only allows limited-size connections??), and not in k-9.
