[Dovecot] can Dovecot do VERP?
by Rick Graves 25 Mar '10

25 Mar '10

Hey, I have several thousand email addresses, the vast majority of which are definitely no good, and I want to figure out which are good. So I will send out an email to all the email addresses. By making a list of the ones that bounced, and comparing that list with the full list, I can determine which are still good. This is for a non-profit association -- I am not in the spam business. Knowing exactly which emails bounced would be much easier if I could set up an in box implementing VERP. http://en.wikipedia.org/wiki/Variable_envelope_return_path In other words, I want an in box accepting all mail where the email addresses match a wildcard pattern like this: mail_admin_??????(a)domain.org, where ?????? are 6 digits. The digits would be a scrambled contact ID. Since they will be digits only, here is the regular expression: mail_admin_\d{6}. (We will pick a wildcard pattern that does not conflict with any existing address on the server.) Sending the outgoing emails, each with a different "From" address matching the wildcard pattern, is not a problem -- I have a working python script for this. The challenge is getting one in box to accept emails with different "From" addresses (matching the wildcard pattern). We are running IMAP server Dovecot 1.0.7. How do I set this up in the IMAP server to accept emails to addresses matching the wildcard pattern? Thanks, Rick Graves

Re: [Dovecot] quota dict with mysql 4.0

(sorry, i only read the digest version of list and always create i new thread by "fake-Re") Hello, >> Perhaps you can implement some updating procedure that >> would only involve a percentage of your users at one time. no way, i want to fix this! but i need help because i have no idea of c-programming. i can read the code a little bit, but never lerned it. solution is to edit dovecot-1.2.11/src/lib-dict/dict-sql.c i can avoid using ON DUPLICATE KEY UPDATE by changing line 91 to: orig: dict->has_on_duplicate_key = strcmp(driver->name, "mysql") == 0; changed: dict->has_on_duplicate_key = strcmp(driver->name, "mysqlXXX") == 0; this works only 50%. if a user has no entry in quotatable, dovecot is updating his quota with 2 queries: INSERT INTO quota (bytes,username) VALUES ('2456','myuser') INSERT INTO quota (messages,username) VALUES ('2','myuser') The first query works, the second throws an error because username-field is uniqe. Duplicate entry 'myuser' for key 1 So i have to find a way to make this query in one step: INSERT INTO quota (bytes,messages, username) VALUES ('2456','2','myuser') or turn the second insert into an update update quota SET messages='2' where username='myuser' But iam afraid this is too much for my c-skills. I need help of an C-Crack or timo as developer. if timo could create a switch for mysql 4.0 would surely be the best. Thanks, Andre

Re: [Dovecot] quota dict with mysql 4.0

Hello, >> I am somewhat surprised that the older software is not compatible with >> the newer version of MySQL. Usually, it is the other way around. Have >> you checked to see if newer versions of the incompatible software >> exist? I would be willing to wager that they have been updated to >> accommodate the newer MySQL versions. Syntax changed a litte bit and also there are some new protected words which are used by older software in sql without backticks etc. I agree updating would be the better way but we talking about a big number of servers and customers still using it. this is not changed over night.... I looked into dovecot-1.2.11/src/lib-dict/dict-sql.c, there seems to be a check for "ON DUPLICATE KEY UPDATE" on line 588. I recompiled dovecot on mysql 4.0 machine and tried again but there was no change. SQL is successful when dataset in quotatable is existing. in this case dovecot triggers an update of the data. But if no line for user is existing in quotatable and an insert is needed there is still the error: sql dict: commit failed: You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near 'ON DUPLICATE KEY UPDATE bytes='12525'' at line why is the mysql 4.0-recompiled dovecot thinking my mysql is able to do "ON DUPLICATE KEY UPDATE"? How to avoid this? Thanks, Andre

[Dovecot] Question howto wiki.dovecot.org about quotas using dict
by Ricardo Barbosa 24 Mar '10

24 Mar '10

Hi, I am configuring a server with postfix and dovecot with virtual domains and using quota. To implement quota followed the documentation of the link http://wiki.dovecot.org/Quota/Dict, did not understand what you mean the field "where_field = path" would be the path on the filesystem of your mailbox? I would have to create the table that he says in the documentation or can I force a value with concat and using the AS (ie select '/var/vmail/domain/user' as path from table) ?

[Dovecot] Is it possible to prevent users from ever deleting anything?
by Snaky Love 24 Mar '10

24 Mar '10

Hi, dear dovecot-users, is it possible to make dovecot ignore the DELETE command for some accounts? Basically what I want to achieve is: users shall not be able to delete their emails - but they still should be able write emails. This is meant for a setup where different users are sending and receiving emails for a "support" account. I looked into IMAP virtual folders and ACL but I did not see a way of totally disabling the possibility to delete emails and share the whole account. I realize there may be race conditions with a setup like this and a web based ticket system might be a better solution, but it is only a very small team and we can always talk to each others to resolve conflicts - so using only one mail account for support seems practical and could keep the overhead small - but we do not want to delete anything from it (accidentaly). Of course, at one point in future somebody has to delete some mails from this accounts to get rid of old stuff - so I would like to implement a super-user that is able to do that kind of mailbox maintanance. How would I use ACL to setup such a scenario? Is it even possible? Or did I misunderstand IMAP shared folders completely??? Thank you very much for your attention! Have a nice day, Snaky

[Dovecot] Writing "sieve" script
by Jerry 24 Mar '10

24 Mar '10

This is probably not the best place to ask this question; however, I figured I had to start somewhere. I want to write a sieve script that can sort incoming mail into specific locations. EXAMPLE: require ["fileinto"]; if header :contains "X-Virus-Status" "Infected" {fileinto "SPAM"; stop;} elsif header :contains "X-SpamCop-Disposition" "Blocked" {fileinto "SPAM"; stop;} elsif address :contains "To" "user1(a)domain.com" {fileinto "INBOX.user1";} elsif address :contains "To" "user2(a)domain.com" {fileinto "INBOX.user2";} elsif address :contains "To" "user3(a)domain.com" {fileinto "INBOX.user3";} # The rest goes into INBOX # The default is "implicit keep", we do it here explicitly else {keep;} This works fine unless user1, user2 and or user3 are all included in the same e-mail address. It is rare; however, it does happen. In that case, a separate message for each recipient would be delivered to the first matching mailbox. The other recipients would not receive any traffic at all. I am new at writing sieve scripts, and have not come up with any way of preventing this from happening. If anyone has a suggestion, I would love to hear it. Even the examples I found by Googling were not really informative. -- Jerry Dovecot.user(a)seibercom.net Disclaimer: off-list followups get on-list replies or get ignored.

[Dovecot] Removing Duplicates
by Sabahattin Gucukoglu 23 Mar '10

23 Mar '10

Hi all, I am starting fresh with a local repository of mails, which almost certainly have duplicates in them. I am going to use maildirs, and ensure all mails are input with CRLFs. The question is: does anybody know how I can find and remove duplicates, either while injecting mail with IMAP, or afterward? I can use tools to find duplicate Message-IDs, but don't know of a way to remove duplicates in mailboxes that are already imported as opposed to incoming mail. Perhaps there is a way to use the IMAP protocol for this? Cheers, Sabahattin
