I have a problem with GMX and Alpine.
Error [Mail not sent: Bad sequence of commands]
In windows it works good, but in Linux when i try to send mail the error message [Mail not sent: Bad sequence of commands] appears.
The same configuration work s on windows, except that in linux version there is not user-id field in config menu but it available in windows, AND when i delete the user-id field in windows same error occures!
Thanks
i solved it.
alpine create header of mail with emtpy From Header.
So i edited .pinerc Customized Headers field:
Customized Headers = From: "fName lName" myaddress@gmx.com
It should be done automatically.
