Sorry, but this patch didn't help. Not with the out of memory, but did it get rid of the double free or corruption error? Hmm. So I guess there's no memory corruption causing this, but I don't really see why it would try to allocate that much memory. 268435472 in hex is 0x1010, which is an interesting number but doesn't really help much either. 268435456 is 256M which is max mail_process_size config setting, maybe this values is in use ? I guess it's just exponentially increasing the buffer size then until it reaches mail_process_size. I recompile dovecot binaries with debug symbols, but seemed that gdb backtrace is broken. Yeah, it is. Hmm. Since the core isn't working, can you attach gdb to imap process while it's still running? So something like: - open the account so imap process starts - gdb -p imap process pid - gdb command: c - cause imap to crash - gdb should stop - gdb command: bt full One more note: version 1.2.4 also has this bug.

Note: I rechecked expire-tool behavior with version 1.2.4 and it's working the same way as 1.2.6, so my problem have more long history, than I thought.

I am quite new to Dovecot with a lot of questions, but I have setup a few email systems now with Dovecot / Exim under Ubuntu.

The patch helped with quotas, but it raises new error - segmentation error After some more tests, I find out that crash happens, while trying to proceed the third user, and the user's quota and other settings not important.
[Dovecot] Post login script issue with pop3 protocol
Hi, all.
I want to track user last login data (ip address, login date, etc)
with dovecot, followed dovecot tutorial[1], and it now works with
IMAP, but failed with POP3. i don't know why.
My script:
LDAP_URI='ldap://127.0.0.1:389'
LDAP_BASEDN='o=domains,dc=iredmail,dc=org'
BIND_DN='cn=vmailadmin,dc=iredmail,dc=org'
BIND_PW='plain_passwd'
if [ X${USER} != Xdump-capability ]; then
ldapmodify -c -x \
-H ${LDAP_URI} \
-D ${BIND_DN} \
-w ${BIND_PW} EOF
dn: mail=${USER},ou=Users,domainName=$(echo ${USER} | awk -F'@'
'{print $2}'),${LDAP_BASEDN}
changetype: modify
replace: lastLoginDate
lastLoginDate: $(date +%Y%m%d%H%M%SZ)
-
replace: lastLoginIP
lastLoginIP: ${IP}
-
replace: lastLoginProtocol
lastLoginProtocol: pop3
EOF
fi
It works with IMAP protocol, but failed with POP3 protocol.

[Dovecot] something similar to last login but for aliases
I'm using dovecot deliver with postfix. Is there a place to hook in a db update when an alias is hit? I'm wanting to delete aliases that haven't been used in x time. Thank you, Brad
