Can't send email (but receiving OK)

[teocali]

Hi,

I can't send emails out... Clicking on Send moves them into the Draft folder, with a message saying: "Attachment /storage/emulated/0/android/data/org.kman.AquaMail/files/contentCopy/..........." with a long list of characters shown, ending with ".jpg is missing open the message and Send to tr" - and I can't see the rest of the message from there on.

When I go into the unsent message, there's a red exclamation mark next to 6 different jpg's I have on my signature.

Any idea what to do next?

Thanks!

It works without the signature, so one step further - thanks!

I wonder what could have gone wrong with the signature as I didn't change a thing and all was working perfectly fine before.

Do you use any "memory cleaning" apps?

There have been cases before of Clean Master removing those "cached" signature images.

There may be other apps of same kind (that "remove unused files" from your phone) which go too far with this "cleaning".
