Hello,
I would like to ask you a question about the PHP imap_open call.
I have an issue with imap_open producing an unreasonable delay when
logging into the Cyrus IMAP server. The delay is exactly 5 seconds and
it is constant across different connections.
1 0.000000 TCP 40496 > imap [SYN] Seq=0 Win=5840 Len=0 MSS=1460
TSV=5166 TSER=0 WS=6
2 0.588600 TCP imap > 40496 [SYN, ACK] Seq=0 Ack=1 Win=5792 Len=0
MSS=1350 TSV=3543919597 TSER=5166 WS=6
3 0.588659 TCP 40496 > imap [ACK] Seq=1 Ack=1 Win=5888 Len=0

^^^^^^^^
7 5.750195 TCP imap > 40496 [ACK] Seq=127 Ack=35 Win=5824 Len=0
TSV=3543924696 TSER=5731
8 5.945506 IMAP Response: 00000000 OK ...
The Cyrus IMAP server is working fine and responds without delay to
non-PHP logins. On the other hand, when imap_open is called for
Courier IMAP server, there is no 5 seconds delay and PHP logins
proceed smoothly.
The code I am using for PHP imap_open is
<?php
$host = "{10.10.10.10:143/notls}";
imap_open($host.mb_convert_encoding("INBOX",
'UTF7-IMAP','UTF-8'),"username","password");
?>
I am new to PHP and would be much grateful to receive pointers for
debugging this issue.
Thank you!
Evgeniy
