Connecting Linux Desktop to NT network
...e been able to connect to our Exchange server for email and our proxy server for Web browsing, but need the file & print sharing to complete the puzzle. I can ping our NT servers by IP address, but not by server name. Is anyone aware of a good reference guide on how to do this? Thanks, Kurt Pritz CGAS Exploration, Inc. kurtp@cgasinc.com

Assertion failure with IMAP NOTIFY
Hi, For a few weeks I've been running a custom notification script[1] that uses IMAP NOTIFY. The script uses a single connection, sets up a NOTIFY watch on a couple of mailboxes + automatic FETCH for the selected mailbox. If a status update arrives for a different mailbox, it selects that box and fetches the mail. Today I got the following error in the log: > Aug 5 14:56:12 karif

segfault when using zlib module with glibc 2.22
Hi, I'm seeing the following segfault when I run `doveadm search mailbox inbox` with the zlib module enabled with dovecot 2.18 and glibc 2.22 on Arch Linux. It does not happen with glibc 2.21. I've noticed that when I remove "zlib" from the mail_plugins line at the beginning of the config file the segfault goes away. I've also tested hg tip and the problem does not appear

[BUG] imap-login segfault when running nmap -sV
Hi, I've noticed that nmap crashes my imap-login (also pop3-login) and narrowed it down to `nmap -sV -p 993 $host`. I've noticed that if I remove "ssl_protocols = !SSLv2 !SSLv3" from my config or enable SSLv3 rather than disabling it the segfault disappears. I'm running on Arch Linux with dovecot 2.2.16-1 and openssl 1.0.2.a-1. I've also attached a network capture, but

FTS lucene indexer-worker segfaulting
Hi, I've just set up fts-lucene and when I run searches on my inbox or when I run the indexer (`doveadm index INBOX`) I get the following segfault. I've run it multiple times and noticed that the data value is different each time so I guess it doesn't always crash at the same point. I'm running dovecot 2.2.13-1 with clucene 2.3.3.4-8 on Arch Linux. If you need any more

The issue is that sendmail/maildrop/postdrop uses setgid to change to the maildrop group (`stat $(which postdrop)`) and the NoNewPrivileges=true setting in the
