[Dovecot] CRAM-MD5 in Python
by Andre 16 Dec '09

16 Dec '09

Hi to all! I’m writing a python module (python+sqlalchemy) to manage user and domain configuration on my system (I hope to get a CLI tool, a Web app and even a native Mac app, via PyObjc, from my lib). I’m implementing password crypto, but I have some problem in generating CRAM-MD5 password, dovecot style. I’ve found an old discussion on this mailing list and a piece of Perl that works, but I need to implement it in Python; I’ve even read code (hmac-md5.c), but before start hard coding (hard from my POV at least, since I’ve never worked with crypto algorithms in a deep way), is there anyone that have had solved the problem or has any idea on how to approach it? TIA Andre

[Dovecot] vpopmail/mysql/quota
by Marty Diesburg 16 Dec '09

16 Dec '09

Hi All, I'm new to the list and have a quota question. I am building a new server with dovecot/qmail/vpopmail/mysql and emails are sending and recieving fine when the quota is set to NOQUOTA, but when the quota is changed qmail doesn't deliver any messages. I have read the docs and still need some help understanding the process for dovecot quotas relating to the vpopmail mysql database they are stored in. Thanks for your help.

[Dovecot] S=xxx missing in new messages
by Andre 16 Dec '09

16 Dec '09

Hi to all! I’m setting up dovecot 1.2.8 on my system to substitute an older IMAP server and I’m testing all features of Dovecot. Yesterday I was testing support for zlib, for compressed messages, to set up a new namespace for old mails and I read that it is safe to compress only mails that have the field “S=XXX” in their name (XXX being the original size of message) and to leave uncompressed the ones that don’t have S=XXX in their name. Testing and searching I discovered that only new mail, mail that used to arrive in mailbox via SMTP have S=XXX, mail copied from another mailbox loose S=XXX. Later I’ve found that this not work anymore, even directly delivered mail messages do not have S=XXX anymore. I use dovecot-lda as delivery program and postfix as SMTP server, but I’ve not touched postfix configuration since one month ago. What can it be? How can I have S=XXX again in my messages file name? TIA Andrea

[Dovecot] Kerberos Cross-Real username
by Nikolay Shopik 16 Dec '09

16 Dec '09

Hi List, Is anyone is running Dovecot with Kerberos and tried to authenticate user from different REALM and have same user principal with default domain. Currently Dovecot only logs user principal w/o REALM. So before I go in production maybe somebody already run into this using Dovecot? If not I just create virtual machines and see how it behaves.

[Dovecot] mail_max_userip_connections
by Richard Stockton 15 Dec '09

15 Dec '09

What is the appropriate setting for mail_max_userip_connections ? My POP3 connections seem to be mostly 1 at a time, but my IMAP connections are often 3 per user per IP. Is this appropriate? If I change the IMAP setting to mail_max_userip_connections=1 will it break things for the user? I am trying to improve this situation: > ps auxwww | grep "imap " | wc 237 3080 22400 TIA, - Richard
