Hi,
today I tested with Thunderbird at PC.
I found out:
1. Profimail has sent HTML and Plaintext (time to say good bye to ProfiMail Go ;-) )
2. Change to "deactivate mobile view" on my Xperia V with Android 4.1.2 corrected the links of other emails - Thank you!
3. An email from Thunderbird (real Plaintext!) looks in Aquamail like this sent from Aquamail, so www-adresses (without http...) and email-addresses are not linked. It would be a fine thing, if this could also be Links in an Plaintext-email.
