attachement filename of outgoing e-mails is cryptic

[clemens.dorda]

Hi EspoCRM-Team,

since version 9.1.0, the attachment's filename of outgoing e-mails is cryptic.

Example: I've sent an e-mail with the following attachment (see filename's first letters in the red box):


Receiver receives the following (Outlook):


When I check my sent mail folder, then I recoginze that the filename is wrong already in the sent mail.

Error Log (nothing related, I suppose - the e-mail sending was at later time):
