[Mailman-Users] genalises - no aliases for one od the ists

[Jutta Wrage]

Hello!

We are using Mailman 2.1.26

Now I discovered a problem:

genaliases creates 2 files and in one of them there is one mailing lists missing.

aliases has 11 lists
virtual-mailman has 10 lists

Is it possible to debug this somehow?
Exim does not accept mail for the missing list: 550 Unrouteable address

/usr/bin/python points to Python 2.7.17

I could add the missing lines in virtual-mailman manually, but once genaliases is run again the additional entries will be up and away again.

Any suggestions?
