According to the documentation of egroupware there is the possibility to add additional (external) email-adresses to a user-account via menu admin > user accounts > edit specific user > e-mail account. After adding the adresses and hitting the Save-Button the screen reloads and the adresses were not saved (fields are blank again).
Trying another way to add additional email-adresses to a user didn't work too. In felamimail under the menu item administration of email-accounts and identities i am able to add additional email-accounts / identities. But i can't uses these identities as sender-adresses in an email.
So does anyone have a clue how to solve this problem? Maybe it's just my lack of understanding how egroupware works... ;-)
Btw, i've several external email-accounts and i wan't to be able to use all email-adresses as sender-adresses. In roundcube it's not a problem, it works fine.
(P.S.: Sry for my bad english...)
