Gents, After browsing the entire archive, i still get no answer to the following error: Use of uninitialized value in numeric eq (==) at /usr/share/perl5/Net/POP3.pm line 310, <PRODUCT> line 4. No messages (support@haringstad.com@localhost) Use of uninitialized value in numeric eq (==) at /usr/share/perl5/Net/POP3.pm line 316, <PRODUCT> line 4. Connection to localhost closed. When i use netcat localhost 110 to login, i use the username & password, and everything goes OK. Running here: Debian Unstable Dovecot as POP/IMAP server with virtual mailboxes, need to login with username@domain.tld Apache 2 The other mailboxes i use, both with windows and Linux clients, work like a charm. Only this not. Reproduced the error with: $OTRSHOME/bin/PostMasterPOP3.pl -d4 -s localhost -u support@domain.tld -p {fakeforthisemail} Anyone? -- Regards, J. van Koll
